Jena, protégé, etc.

Mostly cutting edge (or bleeding edge)

Do it yourself

Classifications OK, object/property libraries not

Web interface

User interface & web server

Dealing with a semwebbed building specification Split existing specification into chapter structure and specification data Converted Dutch 12006-2 version also to chapter structure + linked it with the same spec data Conversion from graduate student’s building instance to specification data That data could be combined with either of the chapter structures Resulting in a formatted building specification
