IT Ontology

Greetings,

I'm interested in locating (or creating) an ontology that deals specifically with companies, people and products in information technology. I have done a little research and have not found any. Does anybody know of such an ontology already in existence? If not, I'd like to create it. I've read up on the subject at the Protégé project site and think I have a good idea how to go about it. However, I'm new to all this semantic web stuff (albeit fascinated by it) and would appreciate some mentor support along the way, if anybody here is experienced in ontology development and would like to give me feedback and suggestions in response to my progress. I am wondering if this is the right forum for such a discussion. Of course, if such a ontology already exists that wouldn't be necessary. At any rate, I'm interested in working on such a project and making it available for anybody to use. I look forward to your thoughts. Thanks. Kevin
