OWL languages
OWL provides three increasingly expressive sublanguages designed for use by specific communities of implementers and users.
- OWL Lite - supports those users primarily needing a classification hierarchy and simple constraints.
- OWL DL - supports those users who want the maximum expressiveness while retaining computational completeness (all conclusions are guaranteed to be computable) and decidability (all computations will finish in finite time).
- OWL Full - is meant for users who want maximum expressiveness and the syntactic freedom of RDF with no computational guarantees.
