The RDF, for Resource Description Framework, is the basic language for semantic web. It proposes a graph model to formally describe web resources and their metadata, in order to allow automatic processing of these descriptions.
A document structured in RDF is a set of triplets.
The ontologies and vocabularies used by data.archives-ouvertes are the following :
- FaBiO, the FRBR-aligned Bibliographic Ontology
- Bibo, Bibliographic Ontology
- Dublin Core
- FOAF
- SKOS, Simple Knowledge Organization System
The dataHAL portal provides :
- a documentation: presentation of the triplestore and the various data schemas
- a SPARQL endpoint: Interface of interrogation of the knowledge base structured in RDF
- downloading of the content of the triplestore: monthly zip archive of the RDF data
