http://purl.org/dc/elements/1.1/description	The RECO ontology defines the vocabulary for representing prefereces-as-constraints and preferences-as-ratings as RDF graphs. This lightweight vocabulary provides domain-independent means to describe user profiles in a coherent and context-aware way. RECO has been designed as an extension of both Friend-Of-A-Friend (FOAF) and Who Am I! (WAI) ontologies.

http://www.w3.org/2000/01/rdf-schema#comment	Patterns are reifications of constraints, which are conditions about the desired or preferred attributes of the resources. A constraint ranges over a set of individuals. RECO considers several kind of constraint expressions: (1) conjunction of constraints: "music from the sixties"; (2) disjunction of constraints: "music or films"; (3) composition of constraints: "cars with powerful engines"; (4) datatype constraints based on boolean operators: "released before 1980".
