Hi Bijan, et al, Here are a few comments on http://webont.org/owl/documents/primer-exp.html. Conrad My most general comment is that it would be better to start with the OWL 1 documents and merge them to reduce redundancy, update for new features, and make corrections and clarifications, rather than start a completely new document. To users OWL 1.1 is a release with some additional expressiveness. It's not a major overhaul. The documentation should reflect that. I don't think the burden should be to comment on this proposed document, but to comment on OWL 1. I used the OWL 1 Reference Manual almost exclusively, and particularly appreciated Appendix B (RDF Schema of OWL), and Appendix C (Quick Reference). Would be good to carry these forward. The buttons for syntax choice are very cool. We need to ensure the document prints properly, perhaps will all the syntaxes by default, because folks printing things out for travel will probably not realize they need to set the buttons first. Section 2.1: It's a very good idea to provide some reasons for the software community at large to pay attention to OWL, which is the purpose of the section. I think this section should to introduce and use the notion of expressiveness, since the concept is usually only implicit in the typical software practitioners thinking. Then the languages can be compared with examples, eg, OWL is more expressive than RDF, OO more expressive (mostly) than DB's, OWL more than (the structual parts of) OO, etc. An important topic to cover is the differences between classification in OWL and OO. To the typical software practioner, OWL looks like yet another OO language, minus the code. They're quite different, of course, and this needs to be brought out. I have a small series of examples that show this. Will send out separately.
