Bicycles, Trucks, and web services specs

Not surprisingly, peace has not broken out in the ongoing dispute over web services specifications described in my last post.

More WS-* specs, more questions about architectural viability

It's as regular as the seasons: as the leaves start to fall from the trees here in Michigan, more web services specifications flutter down from WS-IvoryTower, and more hunters take up their rhetorical shotguns to blast at them.

Tim Bray has yet another must read piece that apparently emerges from the collision of his deep understanding of XML concepts with realities he experiences at Sun.

Xml 2003 Reflections - Adam Bosworth Keynote

Posted by mchampion on December 19, 2003 at 6:58 AM PST

[Another look back at the XML 2003 conference
last week. I feel sortof blogspherically incorrect in waiting a week to write
down these thoughts, but I wanted to let them bounce around a bit, and look at
what others wrote.]

XML 2003 reflections - day 1

Posted by mchampion on December 11, 2003 at 11:50 AM PST

This is the first of several reflections on what I think I learned here at the XML 2003 conference in Philadelphia. Sorry if it's too XML-geeky and not of sufficient interest to Java people, but I think a lot of what I heard people talking about have considerable relevance beyond the XML community they were aimed at.

Ray Ozzie [IMHO but IANAL] effectively demonstrates that 1993-vintage Lotus Notes had "prior art" that -- in a rational world -- would invalidate the Eolas patent on embedded hypermedia. This patent has resulted in a large judgment against Microsoft and raised the very real possibility that the Web browser as we know it must change drastically or infringe on the patent.

Reports of the "Demise of the XML Database" are dubious

Posted by mchampion on October 4, 2003 at 2:30 PM PDT

Phil Howard of Bloor Research presents anargument I've heard more than once recently: "The reason why there is this trend away from pure XML storage is because advanced XML capabilities are being introduced by all the leading relational vendors."

Standards, Stability, and Confusion

Posted by mchampion on August 7, 2003 at 6:38 PM PDT

There are lots of articles and weblogs about standards-related issues recently. Simple news/weblog content syndication "standards" are in the midst of a power struggle, ... Web services management vendors may be squaring up for a standards fight ...

XML can define agreements, but can also help deal with chaos

The contentious world of RSS and the "(not) Echo" project have been featured in a number of weblogs recently by Simon Phipps and Daniel Steinberg.

SOA: One acronym to bind them all?

Posted by mchampion on June 24, 2003 at 7:31 PM PDT

I must confess that when I first started hearing about Service Oriented Architectures or SOAs, my reaction was "oh brother, here we go again ... more vague mumbling about 'paradigm shifts' by analysts who have predicted 10 of the last 2 revolutions." The definitions one finds didn't inspire confidence ...
