1 Co-funded by the European Union under FP7-ICT Co-ordinated by aparsen.eu #APARSEN Achille Felicetti, Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Webinar on Interoperability of Persistent Identifier system- 15/02/212

2 Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN 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

4 Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN 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.

11 Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN D2R Server for prototyping URL: 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 Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN 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 Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN 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 Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN 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
