  • All eagle-i resources are identified by URIs.
  • All resource URIs are HTTP URLs, i.e. they are resolvable.
  • The HTTP protocol is used for content negotiation; the data is available in a variety of formats: RDF/XML, RDF/N3, HTML,...

The data in eagle-i search application indexes this data and leverages its semantics to offer a targeted search. Third party applications can also access the data to present different views of it, incorporate it in other websites, etc.is contributed by Network member institutions. This data can be freely searched using our central search application, but it is also available three other ways, also reachable through https://www.eagle-i.net/export/:

  1. Public SPARQL Endpoints
  2. RDF downloads
  3. Lists of URIs*

  • a SPARQL endpoint (currently with authentication, public SPARQL endpoint forthcoming)
  • a harvest API that lists all published resources in a repository (currently with authentication)

Existing public datasets, via the harvest API:
