Schematron and time: complex event processing?
November 14 2009
I have been thinking a little bit about whether Schematron's pattern approach could be applied to complex event processing where the input is a stream of discrete XML documents, for example each one being a reading from a set of... read moreNovember 14 2009
A couple of people have asked again this week for the RSS feed address for my blog. Here is is: I believe you can get the individual feeds for other bloggers on OReilly sites using the same URL and the... read moreLeaked Draft of EU Interop Framework

A Dutch website has what is claimed to be a leaked late draft in English of European Interoperability Framework for European Public Services (EIF) Version 2.0 read moreAdam Bosworth on picking standards - Rare nerdy technical post
November 11 2009
I enjoyed Adam Bosworth's Talking to DC. But don't his points apply to most software/interface specifications, without being doctrinaire? What is the difference between his Standards work best when they are focused and, say, Agile's YAGNI?... read moreTactical and strategic XML design
November 06 2009
So I guess when we look at a system's architecture, the first thing we can do is ask 'Is this XML here being used strategically or tactically?' A strategic use might be, for example, to allow long-term archiving; a tactical use might be XML in AJAX (where using JSON would… read moreParticipation, participation, participation

IBM marketing guy Rob Weir has half of a new series of blogs The Final OOXML Update up. Readers may be surprised that I agree with many of the points he makes. read moreThe indexed XML website as a commodity - Syndication gone mad?

The client-person doesn't GET a webpage, they get a whole website (this is for B2B not B2C.) read moreNow I have seen everything! - Context-free XML
September 30 2009
I have always thought the context-senstive { a^n, b^n, c^n: n >=1} s was a kind of theoretical construct that you would never see in a real-life XML document. Today, I have actually seen one! read moreWhat are useful Software Engineering approaches for legislated requirements?
September 30 2009
More projects seem to be coming across my desk that ultimately involve building information systems whose primary requirements come from legislation or regulations. And sometimes even the detailed requirements. Legislation is sometimes quite a nice Requirement Specification: it is expressed... read moreThe Norwegians still get it! - Surfer dudes go with Ogg

These all seem the right way to do things: a user decides what it needs for specific uses, is pragmatic or generous about timing, and doesn't exclude any of the technical eco-systems from equal participation. I think it also represents a real challenge to the software vendors: starting 2011 they… read moreSeptember 28 2009
A few months ago, a client wanted to dip their toes in the semantic web. So I took a fresh look at the status quo, and where the current sweet spot is. Here are my conclusions, and how things panned out for this particular job. Your mileage may vary. read moreSeptember 22 2009
A solid refactoring, the kind that you don't do every year, also needs to involve a tooling up, but scoped to making the new desired architecture something that programmers won't subvert but find natural. In a way, the programming languages become the interfaces that provides the boundaries for the layers… read moreW3C Widgets: Yet another XML-in-ZIP file format? - Looks good
September 21 2009
It will be interesting to see how big a widget can get: can it be a full word processor? And what make's widget so different from applets? read moreBeware of browser and OS numbers

For some markets the success/domination by Microsoft is much stronger than blanket figures indicate. read moreSeptember 15 2009
A lot of Schematron can be implemented directly in a mildly enhanced version of RELAX NG without (I think) explosions, before it all runs out of steam. read moreRecent Posts | All Posts
