EulerGUI looks like an attractive and simple API, and I could probably get round the 'only 5 jars' problem by rebundling the collection of jars that's required.

I have enough experience with Jena to know that it is indeed pretty simple. For _all_ these APIs, the basic example of opening up an RDF file and iterating through the contents works out at roughly the same size and complexity. It's just that I also have experience of the look on people's faces when I say, no, RDF _is_ simple, and here's this 20MB jar you need to parse it. It's not the disk space, it's the pages of extra classfile documentation that put off the highly technical, but technically conservative colleagues I'm thinking of. I received a pointer, off-list, to librdf.org, acknowledging that this wasn't Java. I know librdf well, and like it. _That's_ what I'm looking for in Java. I like librdf for all the things it doesn't do, and the comforting air of unshakable stability that it therefore radiates.
