It happens quite a bit. Much of the value of HTML is its ability to
capture and represent knowledge in an informal or semi-formal way.
But folks often run into the boundaries of its expressive capability,
and look for ways out.
The META tag is intended for experiments on the edge of HTML's
expressive capability. I haven't seen "the answer" to this problem
that I'd like to standardize.
The point of my message is to encourage those of you who are seriously
interested in this topic to become familiar with the existing work in
the field: both the traditional library science cataloging (sp?)
stuff, and the more wigged-out AI knowledge representation stuff.
Reading the background literature will show just how interesting
and complex this problem is. Hmm... maybe that's not 100% a good
thing: the web was largely built by folks who didn't know enough
realize that it couldn't be done :-)
