> shouldn’t I have more occurrences?

No, why? Occurrences are just that; pointers to an occurrence of a topic. Quite often people mistake these for properties, and lose quite a lot of semantic metadata in the process. Faceted data values makes best in associations.

I didn't stupdy your map in detail, but you've got it far better than most. Don't be too hard on yourself; it's good stuff.

Comment 2 on /2004/09/08/topicmaphttp://norman.walsh.name/2010/09/25/oauth#comment00022004-09-09T12:14:11Z2004-09-09T12:14:11ZLars Marius Garsholda39a3ee5e6b4b0d3255bfef95601890afd80709

Nice! I agree with Alex that you don't really need occurrences the way you've done this, but maybe the little blurb you have on each essay could become an internal occurrence on the essay? Some of the metadata about the images (e.g. date) might have gotten the same treatment. Also, you've got a few duplicate people, which it would be nice to have merged.

Generally it looks good to me, though there's one thing I might want to change: you use subject indicator references also when the topic represents an information resource. In XTM a resource reference would be better for that.

> I also wonder if there’s an Omnigator tool for RDF

There is, and it's called Omnigator. :) Omnigator can read RDF, and it's quite easy to make it do so if you turn on the RDF2TM plug-in (go to Manage, then Plugins).

> or a cwm for Topic Maps

Not really. It would be nice if such a thing had existed, but as far as I know it doesn't.

A good dead-tree resource is the book, XML Topic Maps edited by Jack Park and Sam Hunting (copyright © 2003 Pearson Education, Inc.). It is basically a collection of chapters - by various authors - explaining XML Topic Maps and how they were used in various settings. The book is like the Charles Goldfarb's "XML Handbook" to the XTM world. Get it from your local library. Here's the Library of Contress Cataloging-in-Publishing Data from page iv:

Hope that's useful!

Just for completeness reasons: The Topic Maps Handbook (an empolis White Paper) is a further reading about Topic Maps. It is positioned between Peppers' TAO paper and Parks' book. You can download it for free at http://www.empolis.com/downloads/empolis_TopicMaps_Whitepaper20030206.pdf
