OAI-ORE
http://www.openarchives.org/ore/logos/ore_logo_e_128.png Open Archives Initiative - Object Reuse and Exchange
General[edit]
OAI-ORE is a standard to describe and identify aggregations on the web. Taking a publication as an example, it mostly consists of multiple resources (publisher pdf, supplementary material, metadata etc.), therefore what we 'see' as an publication is actually the aggregation of multiple resources.
Aggregations should be modelled in respect of the core foundations of the Web
- Resource, an item of interest.
- URI, a global identifier for a Resource.
- Representation
- Link, a directed connection between two Resources.
Basic Principles[edit]

Aggregation (A)[edit]
A non-informative resource
Resource Map (ReM)[edit]
An information resource that describes an aggregation
Data model[edit]
RDF Graph using name spaces:
- dc (http://purl.org/dc/elements/1.1/)
- dcterms (http://purl.org/dc/terms/)
- foaf (http://xmlns.com/foaf/0.1/)
- ore (http://www.openarchives.org/ore/terms/)
- owl (http://www.w3.org/2002/07/owl#)
- rdf (http://www.w3.org/1999/02/22-rdf-syntax-ns#)
Advantages[edit]
General[edit]
- Interoperability
- Modelling of relations
- Detection and processing of relation information
- Following the principles of Linked Data (share structured data on the Web)
Possible new Features[edit]
Tools[edit]
- Java Library (for constructing, parsing, manipulating and serializing OAI-ORE Resource Maps. ATOM, RDF/XML, N3, N-Triples, Turtle and RDFa)
- Foreside Explorer
Steps[edit]
The basic steps to integrate OAI-ORE to eSciDoc (regarding publication data for start) would be:
- Create mapping from eSciDoc Publication Item to ore
- Create mapping from ore to eSciDoc Publication Item
- Make sure that every resource has its own URI
- Expose oai_ore over OAI-PMH
- Implement http part
- Enable SWORD deposit of ore data
