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

PI Reuse



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.

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

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

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.



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.

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
