Siegfried - OntoMat looks very good. Unfortunately, it does not seem to work with _DAML_ ontologies, rather is uses RDFS ontologies. What I mean by that is just this.... In the sample ontology included with OntoMat you have the following namespaces declared: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:daml="http://www.daml.org/2000/12/daml+oil#" xmlns="#"> and this class: <rdfs:Class rdf:ID="Employee"> <rdfs:subClassOf rdf:resource="#Person"/> <!-- Restrictions omitted --> </rdfs:Class> When the class is written as: <daml:Class rdf:ID="Employee"> <daml:subClassOf rdf:resource="#Person"/> <!-- Restrictions omitted --> </daml:Class> it no longer appears in the ontology browser window. The first class is RDFS, but it is NOT DAML+OIL, the second is DAML put your tool ignores it!! The sameClassAs property that linked daml:Class and rdfs:Class has been removed from the DAML+OIL specification, so an ontology that has only rdfs:Classes and rdf:Properties is not DAML. Or at least it is an ontology with no daml:Classes or daml:Properties, which is not very useful as DAML+OIL. By the way, I have the same complaint with OntoEdit. Another fine tool, but it does not produce DAML+OIL, rather it produces RDFS. (last time I looked) How about an option on both of these tools to import/export DAML classes, properties and etc?
