About the Share Family

Revision as of 16:05, 4 April 2023 by Anna Lionetti (talk | contribs)

The Share Family of initiatives based on linked data comprises Share-VDE (Virtual Discovery Environment), Share-Catalogue (the Italian network of university libraries applying the Share principles), Share-Art (designed to support specialist art libraries. Parallel to Share-Art is the Kubikat-LOD pilot project, representing the linked open data entity discovery platform containing the catalogues of the Art History libraries of the Kubikat group), and Share-Music (a future pilot in the music domain). The different characteristics of each field are a useful asset that can be used to the advantage not only of the Share Family as a whole, but for each single discipline.

Being part of the Share – Linked Data Environment means facilitating cataloguing and exposition of bibliographic records in linked data, thus supporting the transition from the traditional cataloguing environment to innovative models applying the linked data paradigm, and providing the LAM - Libraries, Archives, Museums domain and information professionals with a more comprehensive suite of tools at their disposal.

The platform and the other dedicated environments part of the Share Family enhance the discovery potential of library resources and unveil information that would otherwise have been hidden in archives, thus enabling the access to a rich amount of data that can be exported and re-imported by the participating institutions.

The output common to all the branches of the Share Family foresees:

  • the enrichment of original MARC data and of the records converted in linked data with identifiers from external sources (e.g. ISNI, VIAF) and original Share identifiers;
  • the reconciliation and clusterization of entities;
  • the indexing of records in the Cluster Knowledge Base, authoritative environment in linked data;
  • the conversion of library catalogues from MARC to linked data;
  • delivery of converted and enriched data to libraries for reuse in their systems;
  • the publication of library records in linked data on the relative Share discovery platform.

The Share Family technology: the LOD Platform

The technology underlying the systems part of the Share Family is based on the LOD Platform, that is a highly innovative technological framework, an integrated ecosystem for the management of bibliographic, archive and museum catalogues, and their conversion to linked data, extensible as needed for specific purposes.

For more details, see a summary of the main components of the LOD Platform and an extensive description of the framework.

The Share Family technology relies on a tenant infrastructure. In the system architecture, a tenant is a pool of institutions contributing to the same Cluster Knowledge Base. Multiple tenants form the Share Family. Family members can interoperate among respective Cluster Knowledge Bases through a centralized registry.

The Share Family branches (tenants)

The Share Family of initiatives includes different branches and sister projects, supported by the same LOD Platform technology. Each branch or project is hosted in a specific tenant of the system architecture with a corresponding specific Cluster Knowledge Base and a dedicated web entity discovery portal. For more details on the Share Family tenant infrastructure see the Summary of Share Family tenants.

In some cases, within a single tenant a customised skin (ie. a sub-portal of the main entity discovery) can be created to address ad hoc needs of an institution, or group of institutions, willing to expose only their own data or to integrate local services in the Share Family environment. For example, Share-VDE entity discovery portal at is one of such tenants, including a pool of data from a number of institutions, and the respective skin portals.

While the main entity discovery portal of a tenant shows the data of all the institutions feeding the tenant's Cluster Knowledge Base, the skin portal gives the ability to filter only the data of the institution or group of institutions that the skin portal has been designed for.
