  1. Achille Felicetti, Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Webinar on Interoperability of Persistent Identifier system- 15/02/212

  2. Trusted PI Interoperability as enabler for a ) using PI interchangeably (e.g. DOI or NBN for citation) b) increasing the accessibility of an object over time (e.g. if an object is no more available on the publisher database, it can be retrieved from another datasource using the same PI) c) making more reliable operations of grouping and counting (e.g. countability of the scientific productions of an authors) d )Disambiguating and tracking authors and IPR

  3. Multiple PIs scenario in digital object lifecycle Publishes Publisher DOI DOI DOI Thematic rep. PI Reuse + DOI DOI Handle + DOI Handle University IR NBN NBN DOI Deposit NBN DOI National Library

  4. General considerations • The Registration Authorities (RAs) are not aware about the existence of multiple copies of a digital object on Internet and the reuse of a PI in different content providers. • we started from the Content Providers (instead of RA) avoiding to affect the autonomy and business model of RAs • The use of common metadata fields like title, author, etc. is usually not reliable (e.g. typos) • We exploit the PI as a trust metadata value to link the same objects each others.

  5. FRBRoo & CIDOC-CRM FRBR Model Entity-relationship model designed by IFLA FRBR/CIDOC CRM Harmonisation Expressing the IFLA FRBR model with concepts and tools provided by the CIDOC CRM Aligning the two object-oriented models Semantic interoperability between library and museum information

  6. “Learning from repositories” • Early Adopters • CERN – INSPIRE MARCXML • DANS DC • JLIS Open Access Publisher DC • FRD DC

  7. DC, MARC, FRBRoo/CIDOC-CRM Mapping

  8. Trusted PI based co-reference CP4 CP5 CP1 CP2 CP3 Object 5 Object 4 Same as Same as Object 2 Object 1 ARK1 DOI 1 DOI 1 ARK 1 Object 3 NBN 1 NBN 1 Same as DOI 2 Object 1 DOI 2 Object 3 Same as Object 4

  9. Exploiting a trusted co-reference chain “Same as” relation IF Service PI 1 PI 1 C All resources available A PI 2 B PI 3 D PI 4

  10. Prototype Implementation DANS Schema Protocols Dublin Core SRU JLIS SPARQL IKB Dublin Core S1 D2R PI Harvesting & processing FRD SQL RDF OAI-PMH Dublin Core S2 PI OAI-PMH CERN WEB MARCXML Interoperability Services DC-FRBR mapping MARCXML – FRBR mapping WEB CERN - Author proprietary

  11. D2R Server for prototyping URL: http://93.63.166.138/demonstrator/ The prototype uses a FRBRoo based mapping file to map SQL database records into this format, and allows the RDF data to be browsed and searched. Requests from the Web are rewritten into SQL queries via the mapping. This on-the-fly translation allows publishing of RDF from large live databases and eliminates the need for replicating the data into a dedicated RDF triple store

  12. PI – chain of related Objects Input: PI Output: chain of related objects Description: The PI-related PIs service gets all objects related to object identified by the PI in input. This functionality guarantees multiple ways to access the resources and related information, making the object retrieval process reliable.

  13. Countability of Author Publications Input: Author PI Output: List of publications (metadata) taken just once Description: This service retrieves all the objects associated to an Author grouping the same objects in a unique view (exploiting the same as relations based on PIs). The results is a list of views taken only once.

  14. Next Steps To complete the Ontology (work in progress …) Additional test cases and applications Additional Entities and Properties as needed Vocabulary of Types and Roles for Objects and Actors RDF & LOD Publication URLs definition rules Co-reference resolution services Resolver Chains SPARQL queries and endpoints
