The new project SXQuery looks very interesting for me. First, the developers started with the review of current approaches, and their wiki contains a lot of useful information. Second, my efforts are noticed.
Links to the reviews of my articles:
Kevin Tew, one of the participants in the SXQuery project, have written to the ssax-sxml mailing list in order to start conversations and relationships with researchers in the Scheme/XQuery field, and I replied too.
Also, preparing this post, I realized that I need the category "science" and created it.
