I wonder what it is that makes people choose between RDFS or OWL. It seems that people seem to think that RDFS is of better use for more technical, 'sloppy' representation of data, while OWL is of better use for more ontological, concise representation of information. This might have some advantage, as it would allow us to separate these two different grades of ontological consistency. So when we are seeing an ontology formulated in RDFS we expect less ontological commitment than we do with an ontology formulated with RDFS. However, I am not sure if such a separation does really exist (there are quite sloppy OWL ontologies and pretty clean RDF schemas). I do not see many reasons for using RDFS instead of OWL lite or OWL DL when creating new ontologies. First of all, merging an RDFS ontology with an OWL lite/DL ontology always results in an ontology that is OWL Full -- something that most developers of OWL ontologies want to avoid. A little bit of RDFS in a large ontology that otherwise is valid OWL DL will turn the whole ontology into OWL Full. Therefore I would suggest that every new ontology should be developed as OWL lite or OWL DL where possible. Even if we do not want to use reasoning, OWL lite and DL have the advantage that they are less complex than OWL Full and less prone to inconsistencies than RDFS -- and they do not ruin other OWL lite/DL ontologies when they are merged. kind regards, Matthias Samwald
