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-2009-6 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.

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 Co-funded by the European Union under FP7-ICT-2009-6 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.

The results is a list of views taken only once.
