The persistent identification of digital, and human, resources is a crucial issue for the whole information society. Location, discoverability and citability of resources, ranging from raw data to datasets to publications, and people depend on Persistent Identifiers (PI). Some notable experiences have emerged in different domains, like URN in use by research institutes and libraries (NBN) or DOI in use by publishers and libraries, but some weak points still remain: some institutions have not yet implemented a standard identifier system, a global unique technology cannot be expected/imposed, a unique access point to a joint cross-domain service is missing, and added value services tailored on different user communities are still inadequate. To overcome these weaknesses, APARSEN aims at developing an Interoperability Framework and Reference Model (IFRM) for an effective interoperability between credible PI systems.
The approach is to propose a new Interoperability Framework (IF) where any existing Persistent Identifiers (PI) system can participate without changing anything inside its domain, but making available its data with a specific interface compliant with the IF and so common to all the other PI domains overcoming some crucial limits due to the fragmentation in the current scenario.
APARSEN has produced an overview of the current PI systems and criteria for evaluation, design a reference model to describe the interoperability framework and to provide an integrated entry point, and define community-driven added-value services based on persistent identifiers.
