The RECO ontology defines the vocabulary for representing preferences-as-constraints and preferences-as-ratings as RDF graphs.

RECO has been designed as an extension of both Friend-Of-A-Friend (FOAF) and Who Am I! (WAI) ontologies. @en
This ontology shows how AO and ORE ontologies can be used together to define a ResearchObject. This ontology is further customized by the wf4ever ontology. @en
