searching for thesaurus

hi topicmapper,

I'm searching for a thesaurus about Computer Science stuff.
I'm modelling a part of our university in xtm and i want to make 
associations from every course, person, project...... to a topic that 
describes what this course, project is about.
For example "Me is interested in TopicMaps", "This course is about 
Security", "This diploma Thesis is about publish/subscribe"
Does someone know of such a TopicMap?

thanx in advance stefan
