Me and XML in Stockholm

I’ll be talking about XML in Stockholm on June 16th. The event is a one-day tutorial for technical writers, managers and other interested parties, organised by Dokumentinfo. They organise tutorials on various subjects related to document management and archiving, and a yearly conference where I was invited to speak last year.

So far I have few details but I’m pretty sure I’ll manage to include XLink, somehow.

Finally, KDE 4.6 on Debian

Again, title says it all. I’m only a few days into running KDE 4.6 on my desktop but so far it’s superior to any previous 4.x. It feels like, well, it just works. It’s also beautiful; Plasma is finally mature enough to do all those things I read about two years ago.

What doesn’t work all that well is Amarok. It still won’t play CDs (it can now list the CD contents – hooray), and while I do understand that some of these things take time, 1.4 didn’t have any problems in that respect. I still haven’t found an alternative for my every music need but out of spite I’m now running Clementine, an Amarok fork that also doesn’t grasp CDs.

An Even-Simpler Markup Language?

in his blog, Norman Walsh writes about an even-simpler-than-Mixro-XML markup language, inspired in part by John Cowan’s XML Prague poster and by James Clark’s Micro XML ideas. His ideas are well worth a serious consideration–Norm’s ideas are always worth considering–but the purist in me cringes at the idea of allowing more than one root element. I have to say that I find the idea attractive but I’m not really big on change so maybe that is why I hesitate.

The pragmatist in me, on the other hand, also cringes at Norm’s not doing away with namespaces when he has the chance. in my experience they always create more problems than they solve, but on the other hand, my experience tends to be more about strictly controlled environments where the issues one usually wishes to solve using namespaces can be dealt with using other means.

Until Next Year, XML Prague

This year’s XML Prague is over and I miss it already. For a markup geek, XML Prague is heaven. There is always so much to learn, so many great minds and cool new ideas, not to mention Czech beer and the friendly atmosphere of a smaller conference. This was my third consecutive year attending and I very much look forward to the fourth.

Some notes of interest:

  • XML Prague is a great success. The conference sold out before the sessions were announced so next year, it will move to a larger venue.
  • HTML5, last year’s hot topic, was pronounced dead more than once.
  • Michael Kay announced (and demo’d) Saxon Client Edition that allows you to run XSLT 2 on the browser. Very cool. Saxon CE is in alpha but available for testing at www.saxonica.com.
  • JSON seems to be hot this year. I should probably spend some time learning it, especially since I am planning to use it in the CMS we develop at Condesign.
  • George Bina from SyncRO Soft Ltd, the company that makes Oxygen, presented some ideas regarding advanced XML development. While Oxygen is at the centre of many of these, his point was that there should be a standardised way to do it all. Dave Pawson suggested expanding XML catalog files for the job via Twitter, an idea I find plausible.
  • Murata Makoto, a personal hero of mine thanks to his work with Relax NG, presented EPUB3. What those of us who were there will remember, however, is his introduction, expressing his grief over the on-going catastrophe in Japan.

Mobile Sync, Part Three

After (unsuccessfully) banging my head against the wall trying to sync my Ubuntu 10.04 laptop with the Nokia N900, I resorted to the only solution I knew would work.

I wiped out Ubuntu and installed Debian GNU/Linux Sid in its place. Apart from spending a night recovering from a dodgy dist-upgrade, the laptop now works, syncing perfectly with the N900.

Me, I think there is something wrong with Ubuntu 10.04.

More XProc

I’ve been busy reading up on XProc today while walking through W3C’s XProc Test Suite.

An XML pipeline language has been on my wish list ever since my friend Henrik MÃ¥rtensson wrote something called eXtensible Filter Objects (XFO), an XML pipeline language not unlike XProc, about ten years ago and then lost interest, focussing instead on lean theories, business management and such. Some time before he moved on he wrote a Perl implementation of XFO and another friend, David Rosell, wrote a Java version of that, but unfortunate circumstances killed it all after XFO had been implemented for a few of our then-clients at Information & Media.

XProc, of course, does more than XFO ever did, but the ideas are the same. XProc is scratching a persistent itch for me and might (IMO, of course) very well become one of XML’s most important specs to date. For someone like me who is basically a non-programmer, being more of a markup theorist and dochead (to follow Ken Holman’s labelling of the degrees of XML geekery), it’s a wish come true.

Today, in spite of me going through the test suite and reading the spec, I feel that my most important action towards XProc wisdom was to check with Norman Walsh if he’s working on an XProc book yet (he is).

I’m getting there, though. I hope to finish a working pipeline for Cassis TI publishing tomorrow.

XProc

I’m going to spend the next week or two doing a test implementation of XProc for our document management system, Cassis TI. XProc, as some of you will know, is a pipeline processing language for XML processing, in the same vein as pipe processing in the *nix world. It’s intended to standardise and ease XML processing by treating the processing as a black box consisting of smaller black boxes; in other words, what is inside is less interesting than how the in- and outputs are defined and used.

The test is about producing PDF output so it’s nothing fancy or new, but it’s important because I believe we can replace our current backend with an XProc-based processor, making things easier, faster and better for programmers and users alike.
