xml-dev - Re: A Plea for Schemas

[Jerome McDonough <jmcdonou@library.berkeley.edu>]

For what it's worth (and my opinion and $2.50 will buy you a latte at
Starbucks), 
I agree pretty much completely with your rant (except for the gratuitous dig
at the HyTime guys, who History Will Prove Were On The Side of Right).
XML doesn't address the problems of interoperability at the level you're
talking
about, and neither does RDF.  What you're talking about, unfortunately, is
establishing standardized controlled vocabularies, and those are a ton of
work.  They're hellish enough to develop in a relatively small, cohesive
community
like librarians.  There's no way in hell you're going to get competing
companies
to sit down at a table long enough to do this.

I suspect what this will probably mean is a variety of grass-roots efforts
where people
in particular communities who care enough will establish their own schemas
with
controlled vocabularies, and if they see enough use, software companies that 
deal with those communities will start altering their software to make use of
that fact.  I see a possible danger here in that this might start reifying
intellectual
boundaries between communities and make it harder to search for information
outside your common field of intellectual practice.  Schema repositories will
help this problem somewhat by making schemas for intellectual domains you're
not familiar with more generally available, but getting those up and running
will
also involve a lot of hard work.

TANSTAAFL still holds as a universal principle.  But for those who
really care about trying to achieve interoperability and more open exchange
of information, XML will still be used.
