• DOI is the most commonly used by universities, research organizations, archives and publishers
• Handle is mostly used by libraries and archives
• URN is the most widely used by libraries
• Libraries and archives use frequently internal PI systems

Summarizing the results…Summarizing the results…
• Convergence toward few major systems: DOI, Handle, URN.
• Internal solutions mainly adopted for authors and organizations.
• High level of heterogeneity in metadata schema, repository systems and access systems.
• Need of major requirements for PI for digital objects and authors
• Preservation practices quite diffused but…disparity between the need of preservation and the scarce commitment (funding and sustainability)
Envisioning ScenariosEnvisioning Scenarios1) Scenarios on Citability and Metrics services
• Access to the appropriate copy (FRD)• Access to fragments and linked resources (DANS) • Association of multiple author PI with a single person (ESSEX)• Author career tracking and evaluation (FRD)• Researcher profiling with a collaborative index (FRD)
2) Scenarios on Global Resolution services
• Finding aggregated information on a digital objects or author using a PI (UNITN)• Finding information about a resource’s authenticity and availability (DNB) • A machine using a GRS to retrieve metadata and information about a resource’s
