Open Archives Initiative Object Re-use and Exchange (OAI-ORE)

Maintained by the OAI-ORE Executive.

The Open Archives Initiative develops and promotes interoperability standards that aim to facilitate the efficient dissemination of content. OAI-ORE defines formats for the description and exchange of complex digital resources, which the framework calls Aggregations. Aggregations are then described by Resource Maps. Aggregations are groups of related content, whether different formats of the same content such as a PDF vs. a Word document, or content related by derivation such as a source data set and a paper written describing work done based on that data. OAI-ORE is explicitly designed to work with existing web technologies and therefore expose structured metadata to web-based applications. Serializations of the OAI-ORE model are available in Atom, RDF/XML, and RDFa.
