Scowl is a Scala library allowing a declarative approach to composing OWL expressions and axioms using the OWL API.
Build the jar using mvn package, and add to your Scala project. Import org.phenoscape.scowl.OWL._, and Scowl implicit conversions will add pseudo Manchester syntax methods to native OWL API objects.
