Instantiate, Describe, and Identify Aggregations
OAI Object Reuse & ExchangeHerbert Van de Sompel & Michael L. NelsonRIBDA 2009 - Lima, Peru - October 29, 2009
Aggregations 1. The URI of the humanstart page for the arXivdocument. 2. The formats in which thedocument is available:constituents of theaggregation.3. The title of the document.4. The authors of thedocument.5. The creation and lastmodification date of thedocument.6. Identifiers of entities thatare in some mannerequivalent to this document.For example, the DOI of apeer-reviewed article.7. The versions of thisdocument.8. Links to other arXivdocuments in the samecollection.9. Citations made by thisdocument, and citations itreceived from otherdocuments.

Object Reuse and Exchange: A Resource-Centric Approach
• Prior efforts had the repository and metadata records as the center of theinteroperability thinking:
o Including OAI-PMHo Including initial OAI-ORE thinking cf. “Augmenting Interoperability across
Scholarly Repositories”o Unclear what the metadata records were about …
• This approach does not vibe well with the Web:o The Web Architecture knows resources and URIso Requires special treatment by applications that dominate the Web.
- Keep dreaming!

Object Reuse and Exchange: A Resource-Centric Approach
• Fundamental shift in the chosen approach towards interoperability• The Web Architecture as the platform for interoperability• Resources, URIs, and representations as the tools of the ORE interoperability trade• De-facto integration with existing Web applications• Potential of adoption by other communities• Potential of tools created by other communities• ….
