State-of-the-art – Practical

• (Almost) Every project starts with building its own ontology

  • the requirement of sharing!

• big ambiguity in expressions in OWL (e.g. ont/concept, ont#concept; owl:Class, daml:Class), unparseable files

  • only authors are able to process the ontologies

• Editors store in multiple formalisms.

  • mostly only export

• LISP-based ontologies rely on procedures, e.g. only patterns can be searched.
