Hi all,

I've just finished a tutorial on "Vocabularies" for the Dublin Core conference next week. The latest version can be downloaded from:

http://isegserv.itd.rl.ac.uk/public/ajm65/dc2007/tutorial.pdf

In topic 1, I use pictures to present an *informal* model of controlled structured vocabularies. I invented my own diagram conventions, influenced of course by RDF as directed labeled graphs. In topics 4 & 5 I use pictures to explore use of controlled structured vocabularies in retrieval systems.

Maybe useful to the "drawing the pictures" discussion.

Cheers,

Alistair.
