If you care about designing web services and believe in the 'share
schema and contracts, not class' mantra then you'll be interested in XML versioning. I
mentioned pre-PDC that this was a big issue. At the PDC
Doug Purdy presented one approach that Whidbey Indigo will use to
enable versioning with web services.
Just this week Dare Obasanjo has published 'On
Versioning XML Vocabularies' and tonight I noticed that Dave Orchid from BEA also
attacks the topic with his post 'Providing
Compatible Schema Evolution'.
In fact Dave Orchid's whole site seems excellent (it's
my weekend homework since I've only recently subscribed and his feed doesn't contain
the full articles so I can't read him on the train). One good point I noticed
was in this
post:
'Schema authors tend to make tightly coupled Web services because they can't fully
version or evolve them'.
Avoiding this problem will be key if web services are to realize the promises they
are offering today.
