== Introduction ==
The Share Family is committed to fostering cooperation among its member institutions and within the broader GLAM community to showcase the immense value of being part of an initiative developed and driven by libraries for libraries.


The Share Family’s collaborative approach to linked open data results in advanced technology applications for bibliographic descriptions and shared data management tools. Member institutions embrace the recent progress of LOD Platform technology and are empowered by the advantages of linked open data for knowledge sharing.


== Version 3.1.1 and LOD Platform developments ==
The version 3.0.0 of the [[ShareDoc:PublicDocumentation/LODPlatform|LOD Platform]] that was announced [https://bit.ly/SFBulletin_n9_Jul2024 in the latest issue of the Share Family Bulletin] has introduced substantial changes to the technology framework supporting the system. JCricket entity editor and shared cataloguing tool is the major enhancement of v.3.0.0, but the system has undertaken important optimisations in the [[ShareDoc:PublicDocumentation/Release notes|following software releases 3.1.0 and 3.1.1]], which are currently being tested by member institutions.


== Introduction ==
The LOD Platform technology is shared across all environments of the [https://www.share-family.org/ Share Family initiative], and software releases are rolled out to the various [[ShareFamily:Main Page#The%20Share%20Family%20branches%20(tenants)|tenants]] following a dedicated schedule.
The Share Family progress continues, with ongoing efforts dedicated to advancing the [https://wiki.share-vde.org/wiki/ShareDoc:PublicDocumentation/LODPlatform LOD Platform technology] into production workflows, enhancing system components, and transitioning to the new version 3 of our application.  


== Version 3.0.0 release and LOD Platform developments ==
=== Cluster Knowledge Base and data management ===
First of all, we're very excited to announce the major release of the 3.0.0 version of our software! You can find the release notes here: [[ShareDoc:PublicDocumentation/Release notes|https://wiki.share-vde.org/wiki/ShareDoc:PublicDocumentation/Release_notes]].   
'''<big>Entity model and Cluster Knowledge Base</big>'''


This is a major release that introduces many changes in the software and in data processing algorithms. The new version of the [[ShareDoc:PublicDocumentation/LODPlatform|Share Family LOD Platform technology]] framework will be installed in the various environments of [[ShareFamily:Main Page#The%20Share%20Family%20branches%20(tenants)|Share Family tenants]] over the next period.
The LOD Platform currently supports the latest version of the BIBFRAME ontology, and will upgrade the MARC-to-BIBFRAME mapping to the most up to date version. The use of BIBFRAME within the Share Family initiative has been extended to guarantee interoperability with IFLA LRM and with applications not based on BIBFRAME. The [https://zenodo.org/doi/10.5281/zenodo.8332350 SVDE Ontology] is the result of work that has been carried on since last year by the [https://wiki.share-vde.org/wiki/ShareFamily:NewsAndUpdates#Share_Family_Community_updates SEI - Sapientia Entity Identification Working Group], with the svde:Opus entity being the most prominent extension of the ontology.      


The release encompasses the following components of the LOD Platform: Cluster Management Module (which manages the clusters of entities that feed the CKB - Cluster Knowledge Base, also called Entity Knowledge Base), API layer, Front-end module, RDBMS (database), RDFizer (BIBFRAME / RDF conversion module). Being a major release, several important features and new components have been added to the system, ie. Delta processes, UNIMARC services and JCricket entity editor, the platform’s shared cataloguing tool. This release addresses both bug fixes as well as new developments and enhancements.
[[File:opus-work-model UpdateOpusTypes VersioneMia.drawio.png|none|thumb|735x735px]]


The software versions released over time are shared across all layers of [https://www.share-family.org/ Share Family initiative]’s technology. For an overview of the software versions installed on the different environments, see [https://docs.google.com/presentation/d/17rqBd5YPx4LlTs22d8-uMAeZca5sfZp1NARUASPIKEw/edit#slide=id.g213b29c3396_0_0 Share Family AWS environments summary]. 


The summary below describes some of the major and most relevant features, with a high-level mention. Further information on descriptive tasks corresponding to implementations can be found in the release notes.


=== JCricket Entity Editor ===
The output of the SEI Working Group is being incorporated in the LOD Platform components, e.g. the OpusType property is available in the test environment and can be used in the JCricket entity editor that is being tested.
JCricket is the tool for collaborative linked data entity management and shared cataloguing. It enables - according to the BIBFRAME ontology - the entity curation (e.g. creation of new entities, entity modification, the application of entity merge and split functions). The scope is to improve the quality of the Entity Knowledge Base, a source of living data produced through clustering and ongoing update processes. JCricket is a manual application that makes it possible to manage bibliographic data in the form of entities. It empowers professional librarians to enhance the quality of machine-generated data output of MARC to BIBFRAME transformation. Its optimal application is within a large data pool formed through contributions from multiple libraries, such as Share-VDE; therefore, it does not impact original data that reside in member libraries’ systems, unless libraries want to use ad hoc APIs for entity updates both in SVDE and in their local systems, which is also an option.


Initially, Share members are currently testing JCricket under controlled conditions. You can explore more of JCricket in the [[ShareDoc:PublicDocumentation|Public Documentation section]] of the Share Family wiki at [[ShareDoc:PublicDocumentation/LODPlatform/EntityEditor|https://wiki.share-vde.org/wiki/ShareDoc:PublicDocumentation/LODPlatform/EntityEditor]] and check out Tiziana Possemato’s demo of JCricket entity editor at the 2024 Share Family Workshop: https://www.youtube.com/live/8xBeGB3Npls.
A key aspect of LOD Platform data management is the ability to manage data at a very fine granularity level. The aim is to have the [[ShareDoc:PublicDocumentation/LODPlatform/ClusterKnowledgeBase|CKB - Cluster Knowledge Base]] (or Entity Knowledge Base) as a single source of truth for the LOD Platform and Share Family installations. This will improve:


=== Data management ===
* a “format-agnostic” CKB where all input formats converge into one conversion source (eg. MARC21, UNIMARC, native BIBFRAME/RDF eg. from LD4P Sinopia application profiles…);
'''<big>Fine-tuning of data update procedures</big>'''


Data update processes handle ongoing updates (“delta updates” in Share Family jargon), to enable periodic imports of MARC records for continuous update of system data. By “Delta” updates we mean the changes that occur to the library records that are periodically pushed to the LOD Platform, to be published on the discovery portal. The automation of the ingestion in the LOD Platform of updated library records has the purpose of regularly updating the data available through the discovery interface and the other endpoints of the workflow where the data are available. This means updating the data of the clustered entities and the related resources searchable on the discovery interface and in the triplestore, according to the frequency requested by the library.
* improved conversion from MARC to BIBFRAME and vice versa;
* single conversion pipeline from the CKB – removing the conversion pipeline based on MARC.


One of the main pipelines we’re following in this context is the management of attributes through controlled vocabularies instead of literals. This is being achieved by:


* defining each controlled vocabulary in collaboration with the Sapientia Entity Identification Working Group;
* enriching each vocabulary with external authoritative sources (RDA, Library of Congress, FINTO…);
* clustering of controlled vocabularies and assignment of a URI to each value.


<big>'''RDFizer'''</big>
After completing the work on these vocabularies, they will be made available on JCricket.


The RDFizer module that automates the entire process of converting and publishing data in RDF-based BIBFRAME descriptions has implemented conversion for additional MARC21 bibliographic tags and subfields to be compliant with the mapping and conversion rules published by the Library of Congress (version 2.4). As mentioned in [https://wiki.share-vde.org/wiki/ShareFamily:NewsAndUpdates/December2023#Granularization_of_the_Cluster_Knowledge_Base_and_new_conversion_model previous updates], the work is proceeding for creating a finer granularity level in the CKB: all MARC and UNIMARC fields and subfields have been mapped, which will also support the implementations related to Linked Data Fragments (see below).




'''<big>UNIMARC</big>'''


'''<big>Linked Data Fragments</big>'''
The direct management of UNIMARC records in clusterization and reconciliation processes without the “middle step conversion” from UNIMARC to MARC21 has been completed, and a Wikibase instance https://unimarc2bibframe.wikibase.cloud/ documents this work. An update has also been provided at the 6th IFLA UNIMARC Users Meeting in November 2024, with the presentation by Tiziana Possemato and Claudio Forziati [https://wiki.share-vde.org/w/images/c/c4/10_Possemato_Forziati.pdf ''UNIMARC-BIBFRAME Mapping: Evolving Interoperability in Data Modelling''] ([https://youtu.be/uNpQXHTS3pw?feature=shared&t=3561 recording available]).


We are experimenting with a new approach for publishing linked data descriptions in various serialization formats. In big data-driven environments, accessing, querying, and processing vast datasets efficiently is challenging. Linked Data Fragments (LDF) have emerged as a promising paradigm to address these challenges by providing a distributed and scalable approach for publishing and serving Linked Data. As part of this initial investigation, we developed a set of Web APIs that adopt Linked Data Fragments and provide the following benefits: real-time RDF generation and publication, on-demand ontology mapping, and multi-provenance management.  
The related developments had as a result the migration of the SHARE Catalogue platform to the new CKB infrastructure and enhanced entity discovery portal https://www.sharecatalogue-lod.org/ (see also the [https://wiki.share-vde.org/wiki/ShareFamily:NewsAndUpdates#Share_Family_Community_updates updates on Share Family tenants] below).


More will be shared as soon as the proof of concept will be available. In the meantime, access Andrea Gazzarini’s presentation about Linked Data Fragments titled ''Real-Time “RDFization” - How to provide instant Semantic Graphs without any RDF storage'' at the 2024 Share Family Workshop:

* recording: https://www.youtube.com/live/8xBeGB3Npls?t=4071s .


'''<big>UAT – User Acceptance Testing environment</big>'''
In the Share-VDE tenant, sets of real data from SVDE members institutions have been loaded to a UAT (User Acceptance Testing) environment that runs on the latest software version. The purpose is to test the most recent output of the clusterization of SVDE libraries’ data in a small-scale data pool. Members are validating the results of clusterization processes in the common CKB, ie. the quality of data processing, clustering, linked data conversion and entity display on the discovery portal. Input from the SVDE and Share Family community has always been the foundation of the initiative and an added value to developments.




'''<big>UNIMARC</big>'''


Numerous advancements were implemented based on direct mapping between UNIMARC and BIBFRAME. The UNIMARC services development stems from the SHARE Catalogue project and the Italian libraries affiliated to this platform, but it can benefit all institutions adopting UNIMARC. These libraries are involved in a specific project related to the direct management of UNIMARC records in clusterization and reconciliation processes without the “middle step conversion” from UNIMARC to MARC21. All related developments are finalized to allow the migration of the SHARE Catalogue platform to the new CKB infrastructure, according to the above-mentioned approach. This work will be shared with the linked data community through a Wikibase instance https://unimarc2bibframe.wikibase.cloud/ that will be enriched and documented.
'''<big>Data update procedures</big>'''


To learn more about this topic, you can check out ''The SHARE Catalogue: UNIMARC-BIBFRAME Mapping - An Evolving Path'', presented by Claudio Forziati at the 2024 Share Family Workshop.  
Incremental updates of data ingested from member institutions are managed through a dedicated module that has been continuously fine-tuned to streamline and automate the so-called “delta updates” imports. On the Natbib tenant, the institutional portal for the BNB - British National Bibliography currently supports a stable workflow of delta updates ingestion.


* slides: https://bit.ly/SVDE_Workshop2024_slides;
The delta updates workflow will be applied to all tenants as soon as massive data import and indexing will be stable.

=== JCricket Entity Editor ===
Upon the release of the LOD Platform v.3.0.0, JCricket was rolled out in a test environment dedicated to member institutions. The first round of tests has been done in the second half of 2024, and a new testing phase is ongoing. Feedback from testers will be incorporated in the application. You can explore more of JCricket in the [[ShareDoc:PublicDocumentation|Public Documentation section]] of the Share Family wiki at [[ShareDoc:PublicDocumentation/LODPlatform/EntityEditor|LOD Platform Entity Editor - JCricket]] and check out the demo of JCricket entity editor at the [https://youtu.be/sD3qYbx0n0Q BIBFRAME Workshop in Europe 2024] ([https://wiki.share-vde.org/w/images/6/6c/day1_004_SFamily_BFWE_2024.pdf slides] are also available).


JCricket operates on all layers of the LOD Platform entity model (ie. bf:Agent, svde:Opus, svde:Work, bf:Instance, Item). Also, JCricket users see multi-provenance data at individual attribute level. The tracking of the [[ShareDoc:PublicDocumentation/LODPlatform/EntityEditor#Provenance%20and%20Prism|Provenance]] has been implemented since the beginning as a pivotal element to enable entity data curation by cataloguers from different institutions in a shared space.


'''<big>Clusterization processes</big>'''
The evolution of JCricket over time illustrates the progress of the tool and future goals.


For further details on improvements on the Share Family’s clusterization processes, delve into this version’s release notes on the Share Family wiki at [[ShareDoc:PublicDocumentation/Release notes]].   
[[File:JCricket timeline.png|none|thumb|658x658px]]


=== Architecture and infrastructure ===
<big>'''Multi-tenant architecture'''</big>


Multi-tenancy is an infrastructure configuration that allows many clients to share a single instance of a software application and the related infrastructure resources. We have implemented and are rolling out this approach to reduce effort and machine resources needed to set-up and configure a new tenant or an institutional installation within it. This ensures that data is stored and managed in a unified way, optimizing security, scalability, and efficiency. While built for multi-tenancy, the architecture also seamlessly adapts to private deployments for those who require a dedicated installation.


'''<big>Third parties integration</big>'''                           
     
New data workflows are being analysed to support the use of the LOD Platform technology even outside of the Share Family environment, for the integration with ILS / LSP. We are considering several scenarios where the Share linked data system can simultaneously or alternatively operate on local library systems using libraries’ own tools, and share and cooperatively edit linked data resources across different environments using the JCricket entity editor.


The integration with environments and tools like FOLIO, Sinopia and WeCat is proceeding, and a use case for the integration of JCricket and FOLIO will be presented at future conferences this year. A first look at the integration between Share Family technologies and FOLIO was recently presented by Sebastian Hammer and Boaz Nadav Manes at the 2024 Share Family Workshop, in a session named ''FOLIO and Lehigh University Pilot''.

'''<big>New database</big>'''
* recording: https://www.youtube.com/live/8xBeGB3Npls?t=1369s.


=== Front-end enhancements ===
Because the scale of the Share Family environment has been growing at a big data level (particularly for the largest tenant Share-VDE), we are testing a new database solution that would rely on a NoSQL approach. This would ensure scalability and stable performance in massive data imports and incremental updates.
'''<big>Subjects and Concepts</big>'''


We have made improvements to the previous version of Subjects and Concepts display. The concept types implemented in the backend include: Date, Event, Family, Form, Format, Generic Concept, Genre, Language, Meeting, Opus, Organization, Person, Place, Topic. They are returned on the front-end with a basic set of data and relationships with the works connected with the subject.
=== Third parties integration ===
The evolution of the LOD Platform technology encompasses the ability to mutually integrate the data produced with external systems, notably with local ILS and Library Service Platforms and authority sources. This is being achieved through the integration of the LOD Platform tools with local ILS and LSP, or cataloguing modules:


The Subject tab in the Publication page shows the list of subject string and the concepts derived from it:
* Alma: connection to circulation processes have been established; exploration of CRUD APIs together with Alma libraries is in course, to push data from JCricket to Alma;
[[File:Subject tab.png|thumb|547x547px|none]]
* FOLIO: pilot integration in progress with Lehigh University (Share-VDE member and FOLIO adopter); initial tests are completed for the automated data flow from JCricket into FOLIO’s Inventory module. The FOLIO Instance is automatically updated starting from input data in JCricket as the “source of truth”. Further use cases of mutual integration are being analysed and tested.
* Sinopia LD4P BIBFRAME cataloguing module: connection to Sinopia and parsing of Sinopia-generated data has been completed; after the testing phase, Sinopia data will be included in the LOD Platform CKB - Cluster Knowledge Base and edited through JCricket.
[[File:Integrations 1729264956711.png|none|thumb|662x662px]]


By clicking on a subject string, users can see a list of works related to that subject, as well as how the subject string is connected to the concepts it comprises.
This work aims to facilitate a hybrid cataloging environment that retains support for existing MARC-based integrations while developing the flexibility and interconnectedness offered by Share Family-maintained entities. By automating this process, this integration project not only enhances the metadata management capabilities of libraries but also paves the way for seamless collaborative cataloging within the Share Family community.

=== Front-end enhancements ===
The majority of front-end enhancements has been devoted to improving JCricket, also as a consequence of users’ feedback and tests, as well as following the evolution of the tool. Ongoing optimisations include not only design revisions, but also data curation features. Just a few examples:


'''<big>Small revamping to look and feel</big>'''
* the Provision Activity block of information structures publication data by mirroring the corresponding RDF group of publication attributes, and ensures better identification and reconciliation of Publishers.
* The ability to edit svde:Work data (as mentioned above, JCricket operates on all layers of the LOD Platform entity model).
* A preview of RDF entity representation has been designed and will be implemented.


As part of the UX/UI working group's activities, it was decided to switch to sans-serif fonts for a modern look and feel. Additionally, elements on the homepage of https://www.natbib-lod.org/ have been resized to create a more harmonious and visually appealing design.
The presentation layer of the discovery portal is also being improved, especially as far as accessibility for visually impaired users is concerned. Work is ongoing to validate the accessibility features of the web portal to confirm compliance with international guidelines. Also, refinements are ongoing to the management of Arabic script on the user interface. This task complements the management of multilingualism of Share Family data, that is already handled in two fashions:


* Clusterization processes (automated processes): in this case, the variant forms in various languages and scripts retrieved from the available national and international data sources are used to enable the end user to perform searches on the discovery portal using different scripts and getting the same results.
* Using JCricket entity editor (manual process): in this case, cataloguers can enrich the entity cluster with variant forms in terms of both different languages and different scripts.


== Community work ==


'''<big>Portal switch mechanism</big>'''
=== New Open Metadata Policy ===
The Share Family strives to support and invest in open data to freely share information, and an updated [https://bit.ly/ShareFamily-Open-Metadata-Policy Open Metadata Policy] has been approved by its Advisory Council. The community is committed, wherever possible, to share data transformed by its series of Linked Open Data (LOD) processes. 


A new Switch site button has been added at the bottom of svde.org portal group and skin / institutional portals homepages internal pages ([[ShareDoc:PublicDocumentation/LODPlatform/DiscoveryInterface|see definitions of portal groups and skin portals]]). This button opens a menu where users can select through which portal they want to explore. The aim is to connect portal groups with the related skin portal, so that end users have an immediate overview of what individual skin portals are connected to a portal group.
The [https://bit.ly/SVDE-Open-Metadata-Policy previous version of the policy] was published in 2023 to encourage open access to data produced by Share Family processes.
[[File:Switch site.png|thumb|584x584px|none]]


Overall, the majority of fixes and enhancements extend to rectifying data retrieval errors and fine-tuning data retrieval errors, culminating in a more uniform and seamless user interaction with the system. Across the board, these efforts work cohesively to bolster the system's intuitiveness and reliability, facilitating smoother navigation and ensuring precise data representation.
=== Share Family Community updates ===
As usual, exchanges within the Share Family community steer the vision and the evolution of the initiative and the output of working groups nurtures technical developments:


== Share Family community work and cooperation ==
* The [[ShareVDE:Members/Share-VDE working groups#SVDE-AC%20Sapientia%20Entity%20Identification%20working%20group%20(SEI)|Sapientia Entity Identification Working Group]] is committed to the [https://zenodo.org/doi/10.5281/zenodo.8332350 SVDE Ontology] to define svde:Opus entity properties for different content types. RDA properties are also taken into account in framing the ontology, and this will ensure greater interoperability.
The Share Family is committed to fostering cooperation among its member institutions to showcase the immense value of being part of an initiative developed and driven by libraries for libraries.  
* The [[ShareVDE:Members/Share-VDE working groups#SVDE-AC%20User%20Experience.2FUser%20Interface%20working%20group%20.28UX-UI.29|User Experience – User Interface Working Group]] continues working jointly with the [[ShareVDE:Members/Share-VDE working groups#Share%20Family%20National%20Bibliographies%20working%20group%20.28Natbib.29|National Bibliographies Working Group]] on a design proposal for the Publication page of the entity discovery portal, focusing on the aggregation of svde:Work and bf:Instance data. The group has narrowed down the core metadata for each material type and is now deciding how to display additional metadata that is not core to publication identification, with the aim of improving navigation and optimizing how end-users interact with and utilize the data.  


Ongoing conversations with consortia representatives are underway to define the configurations of this innovative collaboration.  
On 19th September 2024 an informal Share Family meeting dedicated to members was held in Helsinki, at the National Library of Finland, after the two-day BIBFRAME Workshop in Europe. The engagement of the membership around key areas of development confirmed the added value of being part of an active and diverse community.


As an example of this effort, the [https://bit.ly/SF-Executive-Summary-Consortia Share Family Executive Summary for Consortia] offers additional insights into how the Share Family can assist consortia in transitioning to linked open data, providing valuable strategies and support. Approved by our Advisory Council, the document emphasizes Share Family’s pivotal role in aiding consortia in adopting linked data methodologies for enhanced collaboration. The Share Family aims to empower consortia with the tools and knowledge necessary to seamlessly integrate linked open data principles, fostering innovation and interoperability within consortia networks.
On behalf of the various [[ShareFamily:Main Page#The%20Share%20Family%20branches%20(tenants)|Share Family tenants]] we are happy to mention important advancements:


=== Share-VDE and Share Family Working Groups ===
* The Share Catalogue tenant has transitioned to the latest version of the LOD Platform, which includes the advanced entity discovery portal and JCricket. The new version is online at https://www.sharecatalogue-lod.org/ and will be enhanced in the next period as far as data quality and data curation functions.
Working Groups are the backbone of Share Family activities, which are driven by input from member institutions in a joint effort with Share Staff.
* The NLN - National Library of Norway joined the [https://natbib-lod.org National Bibliographies tenant]. Already a member of the SVDE tenant contributing its catalogue, the NLN will also provide the Norwegian national bibliography data and will be the second institution feeding this tenant along with the British Library.
* The beta British National Bibliography in linked data is stable in the institutional portal https://bl.natbib-lod.org, which is populated with regular updates.
* The Parsifal tenant https://parsifal.urbe.it/parsifal/ is effectively enabling the URBE network in the curation of a shared authority file originally created through the aggregation of the catalogues from participating libraries. We are working on a dashboard that orchestrates the workflow between the central authority file and the Cluster Knowledge Base, to facilitate individual libraries’ operations.


Important tasks are being carried on to support the complete shaping of the [https://zenodo.org/doi/10.5281/zenodo.8332350 SVDE Ontology] within the [[ShareVDE:Members/Share-VDE working groups#SVDE-AC%20Sapientia%20Entity%20Identification%20working%20group%20(SEI)|Sapientia Entity Identification group]]: at the time of writing, the definition of the Opus type individuals is being consolidated (ie. the addition to the ontology of the definitions of the various types of Opus, ie. abstract works and resources that the entity model can support). These additions will be reflected by both the general search and discovery portal, as well as in JCricket Entity Editor.
All members are welcome to contribute expertise, specific experience and bibliographic information for the enrichment of a collective catalogue and the entire Share community.


More on the work carried out on the Opus types was shared by Nancy Lorimer at the 2024 Share Family Workshop in her ''SVDE Ontology - Update July 2024''.
=== Collaborations with the library community ===
The Share Family team and member institutions continue to nurture the liaisons with the library information experts and linked data and BIBFRAME communities, to increase interoperability to the advantage of new bibliographic and linked data workflows and to enhance existing ones.

The [[ShareVDE:Members/Share-VDE working groups#SVDE-AC%20User%20Experience.2FUser%20Interface%20working%20group%20.28UX-UI.29|User Experience – User Interface Working Group]] cooperating with the [[ShareVDE:Members/Share-VDE working groups#Share%20Family%20National%20Bibliographies%20working%20group%20.28Natbib.29|National Bibliographies Working Group]] has analyzed the front-end layer of the entity discovery portals according to a set of evaluation criteria (including for example usability and accessibility, consistency of design and navigation, overall user friendliness, integration with SVDE features and local library discoveries etc.), and is now revising a new design proposal for the Publication page of the entity discovery portal, presenting the aggregation of Work and Instance data. Also the relationship between publication data and the connected item data are being reviewed by identifying user tasks for publication and item data discovery, to support better navigation and end user data consumption.


=== IFLA, Linked data and BIBFRAME communities ===
Share Family members continue to play an active role in the library information and linked data communities.


Tiziana Possemato takes on the role of Official liaison IFLA Bibliography Section / Share Family National Bibliographies group, formerly held by Maud Henry from KBR - Royal Library of Belgium. This will ensure the continuation of the collaboration with the IFLA Bibliography Section that Tiziana is already a member of. Related to IFLA activities, a presentation was given at IFLA Midterm meeting of the IFLA Section Preservation and Conservation (PRESCONS), on March 22 2024, by Tiziana Possemato, on the topic of [https://wiki.share-vde.org/w/images/b/ba/Share_Family_-_Vaticana_-_2024-Mar-22_WIKI-min.pdf The Share Family initiative to bring Linked Open Data into practice].
'''<big>RDA Steering Committee</big>'''


Share-VDE participation in the [https://wiki.lyrasis.org/pages/viewpage.action?pageId=249135298 BIG - BIBFRAME Interoperability Group] established to create guidelines for data exchange in BIBFRAME, continues successfully, This cooperation with organisations and projects in the BIBFRAME community will foster the extension of the methods and tools shared by linked data nodes for BIBFRAME interoperability.
A [https://www.rdatoolkit.org/sites/default/files/uploads/RSC_Chair_2025_9_BIBFRAME_protocol_ShareVDE_2025_0.pdf liaison protocol] has been signed to establish the relationship at the strategic level between the Share Family Advisory Council and the RSC - RDA Steering Committee.  


== Information resources ==
This step is considered particularly fruitful also in consideration of the activities that libraires from different countries and continents are bringing forward in the Share Family Working Groups with the scope of enhancing the practical implementations and the concrete interoperability of the emerging bibliographic ecosystem based on linked open data. The protocol has been published:
To facilitate the continuous exchange of ideas and principles that collectively define the vision, aims, and progress of Share Family environments and their tools, new materials and accompanying documents have been created to guide member institutions through this process. By utilizing shared materials and documents, member institutions can seamlessly integrate into the Share Family, actively participate in collaborative initiatives, and contribute to the ongoing development and success of the endeavor.

Introduction

The Share Family is committed to fostering cooperation among its member institutions and within the broader GLAM community to showcase the immense value of being part of an initiative developed and driven by libraries for libraries.

The Share Family’s collaborative approach to linked open data results in advanced technology applications for bibliographic descriptions and shared data management tools. Member institutions embrace the recent progress of LOD Platform technology and are empowered by the advantages of linked open data for knowledge sharing.

Version 3.1.1 and LOD Platform developments

The version 3.0.0 of the LOD Platform that was announced in the latest issue of the Share Family Bulletin has introduced substantial changes to the technology framework supporting the system. JCricket entity editor and shared cataloguing tool is the major enhancement of v.3.0.0, but the system has undertaken important optimisations in the following software releases 3.1.0 and 3.1.1, which are currently being tested by member institutions.

The LOD Platform technology is shared across all environments of the Share Family initiative, and software releases are rolled out to the various tenants following a dedicated schedule.

Cluster Knowledge Base and data management

Entity model and Cluster Knowledge Base

The LOD Platform currently supports the latest version of the BIBFRAME ontology, and will upgrade the MARC-to-BIBFRAME mapping to the most up to date version. The use of BIBFRAME within the Share Family initiative has been extended to guarantee interoperability with IFLA LRM and with applications not based on BIBFRAME. The SVDE Ontology is the result of work that has been carried on since last year by the SEI - Sapientia Entity Identification Working Group, with the svde:Opus entity being the most prominent extension of the ontology.

opus-work-model UpdateOpusTypes VersioneMia.drawio.png


The output of the SEI Working Group is being incorporated in the LOD Platform components, e.g. the OpusType property is available in the test environment and can be used in the JCricket entity editor that is being tested.

A key aspect of LOD Platform data management is the ability to manage data at a very fine granularity level. The aim is to have the CKB - Cluster Knowledge Base (or Entity Knowledge Base) as a single source of truth for the LOD Platform and Share Family installations. This will improve:

  • a “format-agnostic” CKB where all input formats converge into one conversion source (eg. MARC21, UNIMARC, native BIBFRAME/RDF eg. from LD4P Sinopia application profiles…);
  • improved conversion from MARC to BIBFRAME and vice versa;
  • single conversion pipeline from the CKB – removing the conversion pipeline based on MARC.

One of the main pipelines we’re following in this context is the management of attributes through controlled vocabularies instead of literals. This is being achieved by:

  • defining each controlled vocabulary in collaboration with the Sapientia Entity Identification Working Group;
  • enriching each vocabulary with external authoritative sources (RDA, Library of Congress, FINTO…);
  • clustering of controlled vocabularies and assignment of a URI to each value.

After completing the work on these vocabularies, they will be made available on JCricket.


UNIMARC

The direct management of UNIMARC records in clusterization and reconciliation processes without the “middle step conversion” from UNIMARC to MARC21 has been completed, and a Wikibase instance https://unimarc2bibframe.wikibase.cloud/ documents this work. An update has also been provided at the 6th IFLA UNIMARC Users Meeting in November 2024, with the presentation by Tiziana Possemato and Claudio Forziati UNIMARC-BIBFRAME Mapping: Evolving Interoperability in Data Modelling (recording available).

The related developments had as a result the migration of the SHARE Catalogue platform to the new CKB infrastructure and enhanced entity discovery portal https://www.sharecatalogue-lod.org/ (see also the updates on Share Family tenants below).


UAT – User Acceptance Testing environment

In the Share-VDE tenant, sets of real data from SVDE members institutions have been loaded to a UAT (User Acceptance Testing) environment that runs on the latest software version. The purpose is to test the most recent output of the clusterization of SVDE libraries’ data in a small-scale data pool. Members are validating the results of clusterization processes in the common CKB, ie. the quality of data processing, clustering, linked data conversion and entity display on the discovery portal. Input from the SVDE and Share Family community has always been the foundation of the initiative and an added value to developments.


Data update procedures

Incremental updates of data ingested from member institutions are managed through a dedicated module that has been continuously fine-tuned to streamline and automate the so-called “delta updates” imports. On the Natbib tenant, the institutional portal for the BNB - British National Bibliography currently supports a stable workflow of delta updates ingestion.

The delta updates workflow will be applied to all tenants as soon as massive data import and indexing will be stable.

JCricket Entity Editor

Upon the release of the LOD Platform v.3.0.0, JCricket was rolled out in a test environment dedicated to member institutions. The first round of tests has been done in the second half of 2024, and a new testing phase is ongoing. Feedback from testers will be incorporated in the application. You can explore more of JCricket in the Public Documentation section of the Share Family wiki at LOD Platform Entity Editor - JCricket and check out the demo of JCricket entity editor at the BIBFRAME Workshop in Europe 2024 (slides are also available).

JCricket operates on all layers of the LOD Platform entity model (ie. bf:Agent, svde:Opus, svde:Work, bf:Instance, Item). Also, JCricket users see multi-provenance data at individual attribute level. The tracking of the Provenance has been implemented since the beginning as a pivotal element to enable entity data curation by cataloguers from different institutions in a shared space.

The evolution of JCricket over time illustrates the progress of the tool and future goals.

Architecture and infrastructure

Multi-tenant architecture

Multi-tenancy is an infrastructure configuration that allows many clients to share a single instance of a software application and the related infrastructure resources. We have implemented and are rolling out this approach to reduce effort and machine resources needed to set-up and configure a new tenant or an institutional installation within it. This ensures that data is stored and managed in a unified way, optimizing security, scalability, and efficiency. While built for multi-tenancy, the architecture also seamlessly adapts to private deployments for those who require a dedicated installation.


New database

Because the scale of the Share Family environment has been growing at a big data level (particularly for the largest tenant Share-VDE), we are testing a new database solution that would rely on a NoSQL approach. This would ensure scalability and stable performance in massive data imports and incremental updates.

Third parties integration

The evolution of the LOD Platform technology encompasses the ability to mutually integrate the data produced with external systems, notably with local ILS and Library Service Platforms and authority sources. This is being achieved through the integration of the LOD Platform tools with local ILS and LSP, or cataloguing modules:

  • Alma: connection to circulation processes have been established; exploration of CRUD APIs together with Alma libraries is in course, to push data from JCricket to Alma;
  • FOLIO: pilot integration in progress with Lehigh University (Share-VDE member and FOLIO adopter); initial tests are completed for the automated data flow from JCricket into FOLIO’s Inventory module. The FOLIO Instance is automatically updated starting from input data in JCricket as the “source of truth”. Further use cases of mutual integration are being analysed and tested.
  • Sinopia LD4P BIBFRAME cataloguing module: connection to Sinopia and parsing of Sinopia-generated data has been completed; after the testing phase, Sinopia data will be included in the LOD Platform CKB - Cluster Knowledge Base and edited through JCricket.

This work aims to facilitate a hybrid cataloging environment that retains support for existing MARC-based integrations while developing the flexibility and interconnectedness offered by Share Family-maintained entities. By automating this process, this integration project not only enhances the metadata management capabilities of libraries but also paves the way for seamless collaborative cataloging within the Share Family community.

Lookup on authoritative sources such as Wikidata is also being developed to query and pull data while using JCricket. An endpoint has been set-up to query Wikidata Agents and Works via API and SPARQL. Currently, this implementation lives in the internal development environment.

Finally, efforts to integrate LOD Platform features in other applications are progressing steadily also on other fronts. Two conference presentations by Jim Hahn (University of Pennsylvania) have demonstrated some of the options for interoperability supported by JCricket and LOD Platform search APIs:

Front-end enhancements

The majority of front-end enhancements has been devoted to improving JCricket, also as a consequence of users’ feedback and tests, as well as following the evolution of the tool. Ongoing optimisations include not only design revisions, but also data curation features. Just a few examples:

  • the Provision Activity block of information structures publication data by mirroring the corresponding RDF group of publication attributes, and ensures better identification and reconciliation of Publishers.
  • The ability to edit svde:Work data (as mentioned above, JCricket operates on all layers of the LOD Platform entity model).
  • A preview of RDF entity representation has been designed and will be implemented.

The presentation layer of the discovery portal is also being improved, especially as far as accessibility for visually impaired users is concerned. Work is ongoing to validate the accessibility features of the web portal to confirm compliance with international guidelines. Also, refinements are ongoing to the management of Arabic script on the user interface. This task complements the management of multilingualism of Share Family data, that is already handled in two fashions:

  • Clusterization processes (automated processes): in this case, the variant forms in various languages and scripts retrieved from the available national and international data sources are used to enable the end user to perform searches on the discovery portal using different scripts and getting the same results.
  • Using JCricket entity editor (manual process): in this case, cataloguers can enrich the entity cluster with variant forms in terms of both different languages and different scripts.

Community work

New Open Metadata Policy

The Share Family strives to support and invest in open data to freely share information, and an updated Open Metadata Policy has been approved by its Advisory Council. The community is committed, wherever possible, to share data transformed by its series of Linked Open Data (LOD) processes.

The previous version of the policy was published in 2023 to encourage open access to data produced by Share Family processes.

Share Family Community updates

As usual, exchanges within the Share Family community steer the vision and the evolution of the initiative and the output of working groups nurtures technical developments:

  • The Sapientia Entity Identification Working Group is committed to the SVDE Ontology to define svde:Opus entity properties for different content types. RDA properties are also taken into account in framing the ontology, and this will ensure greater interoperability.
  • The User Experience – User Interface Working Group continues working jointly with the National Bibliographies Working Group on a design proposal for the Publication page of the entity discovery portal, focusing on the aggregation of svde:Work and bf:Instance data. The group has narrowed down the core metadata for each material type and is now deciding how to display additional metadata that is not core to publication identification, with the aim of improving navigation and optimizing how end-users interact with and utilize the data.

On 19th September 2024 an informal Share Family meeting dedicated to members was held in Helsinki, at the National Library of Finland, after the two-day BIBFRAME Workshop in Europe. The engagement of the membership around key areas of development confirmed the added value of being part of an active and diverse community.

On behalf of the various Share Family tenants we are happy to mention important advancements:

  • The Share Catalogue tenant has transitioned to the latest version of the LOD Platform, which includes the advanced entity discovery portal and JCricket. The new version is online at https://www.sharecatalogue-lod.org/ and will be enhanced in the next period as far as data quality and data curation functions.
  • The NLN - National Library of Norway joined the National Bibliographies tenant. Already a member of the SVDE tenant contributing its catalogue, the NLN will also provide the Norwegian national bibliography data and will be the second institution feeding this tenant along with the British Library.
  • The beta British National Bibliography in linked data is stable in the institutional portal https://bl.natbib-lod.org, which is populated with regular updates.
  • The Parsifal tenant https://parsifal.urbe.it/parsifal/ is effectively enabling the URBE network in the curation of a shared authority file originally created through the aggregation of the catalogues from participating libraries. We are working on a dashboard that orchestrates the workflow between the central authority file and the Cluster Knowledge Base, to facilitate individual libraries’ operations.

All members are welcome to contribute expertise, specific experience and bibliographic information for the enrichment of a collective catalogue and the entire Share community.

Collaborations with the library community

The Share Family team and member institutions continue to nurture the liaisons with the library information experts and linked data and BIBFRAME communities, to increase interoperability to the advantage of new bibliographic and linked data workflows and to enhance existing ones.

Moreover, participation in international working groups and networks is strategic to the Share Family community, and responds to its core principle of creating connections and increasing communication across initiatives and projects.


RDA Steering Committee

A liaison protocol has been signed to establish the relationship at the strategic level between the Share Family Advisory Council and the RSC - RDA Steering Committee.

This step is considered particularly fruitful also in consideration of the activities that libraires from different countries and continents are bringing forward in the Share Family Working Groups with the scope of enhancing the practical implementations and the concrete interoperability of the emerging bibliographic ecosystem based on linked open data. The protocol has been published:


IFLA

As a member of theIFLA Bibliography Section, Tiziana Possemato is also the official liaison IFLA Bibliography Section / Share Family National Bibliographies group.

Highlights from two IFLA events:


PCC - Program for Cooperative Cataloguing

Share Family representatives have been involved at various levels in PCC - Program for Cooperative Cataloguing activities including various stakeholders:


BIG - BIBFRAME Interoperability Group

The Share-VDE participation in the BIG - BIBFRAME Interoperability Group is strengthening cooperation among institutions adopting BIBFRAME internationally. Recently, Xiaoli Li, Tiziana Possemato and Kalli Mathios presented at the IFLA Advisory Committee on Standards Symposium in Athens, on March 19th, sharing insights from BIBFRAME Interoperability Group: Tackling Implementation Challenges Across Institutions.


Consortia

We are striving to share the benefits of the Share Family approach to consortia and networks of institutions working with shared practices. The LOD Platform entity identification and reconciliation processes are suitable to environments that are already designed to be shared spaces. The potential for consortia of applying Share Family principles and tools is being investigated in a cooperative effort with consortia representatives. The Share Family Executive Summary for Consortia sketches the outcomes envisioned when supporting consortia in adopting linked data methodologies for enhanced collaboration.
