    XML Namespaces - Spike Milligan style
A. There is nothing at the end of that namespace URI you know.
B. Then I won't dereference it.
A. But it might contain something we don't need to know!
B. Then I'd better dereference it to find out what isn't there.

    Interesting optical trick on a FoneBlog
Stare at it for 60 seconds. Close your eyes. What do you see? Very clever.

    A good example of a semantic shadow for knowledge representation - FOAF-XML
Simon St. Laurent has implemented a mapping between a simple XML language - tuned to the problem domain - and its more general, but way more abstract RDF representation. This is a very nice example of what I referred to as a 'semantic shadow' in RDF and other monkey wrenches.

    No ISSN's for Irish Blogs
I read about ISSN's for weblogs and made a few enquiries. Quoting from the reponse:
    Certain categories of on-line publication are also eligible for ISSNs, weblogs, being specifically excluded.

Oh, well.

    Sublinking...or something
Dorothea wonders:

    "Has any enterprising lit-critter come up with a term yet for what I just did in the last paragraph? Undercutting the literal meaning of the sentence on the page with the links I tied to it? Somebody must have. I see people doing this all over the place; I surely didn’t invent it.)"

Beats me.

Overheard at Extreme Markup (easily the best conference I've never been to) as reported on xmlhack:
    "Implementability was not a goal of the Schema Working Group."

I'd laugh if I could find room through the tears :-/
