I wrote a lot about XML and RDF for various publications back when there were publications that would pay for it. Now I mostly just write for my blog.

The XML FAQ quotes me a few times.
From December 1997 to January 2000 I wrote a column on XML for the SGML newsletter <TAG>. (other articles)
A semi-scientific study of what attributes of the HTML a attribute real people actually use.

At the SGML '95 conference in Boston, I presented a talk based on the paper entitled "Object-Oriented Development of SGML Applications" that I did as part of my masters degree program at NYU. The conference paper accompanying the presentation was cited in the SGML Technologies Group paper "Object Orientation and SGML: LINK Revealed" (paper no longer available on line; see bibliographic entry under "[CR: 19961226]") and several papers at subsequent conferences.
I used to maintain a web page of databases claiming to support SGML. It's very out of date at this point; I recommend Ronald Bourret's more recent XML and Databases.
The SGML/XML Web Page is the ultimate reference on all that's available in the world of XML and SGML. (Note that it's searchable.)
