Co-funded by the European Union under FP7-ICT-2009-6 Achille Felicetti, Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Webinar on Interoperability of Persistent Identifier system- 15/02/212 Co-ordinated by aparsen.eu #APARSEN Co-funded by the European Union under FP7-ICT-2009-6 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 Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 aparsen.eu #APARSEN Co-funded by the European Union under FP7-ICT-2009-6 Multiple PIs scenario in digital object lifecycle Publisher DOI Publishes DOI DOI Thematic rep.

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 Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 aparsen.eu #APARSEN Co-funded by the European Union under FP7-ICT-2009-6 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. Emanuele Bellini, Cinzia Luddi Fondazione Rinascimento Digitale Interoperability of Persistent Identifier systems Florence - 13/12/2012 aparsen.eu #APARSEN Co-funded by the European Union under FP7-ICT-2009-6 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.
