XProc: An XML Pipeline Language

Want to convert your favorite specification to ePUB? Here are the tools that I've been using. [Update: 10 June 2010] Much revised.

Playing with ePUB. In this episode, ePUB versions of W3C specifications. [Update 10 June 2010] Regenerated with stricter compliance to the ePUB rules; added a few more. Plus pretty covers!

A look at the intersection of the XML model PI, the XML stylesheet PI, and XProc.

Taking another stab at the long-standing problem of producing DTD (and XSD) versions of the DocBook V5.0 family of schemas.

I'm pleased to report that XProc: An XML Pipeline Language is now a W3C Proposed Recommendation.

Early in January, a new XProc draft will appear. It will be a Last Call Working Draft, a step backwards in the process, or maybe just a half-step. The reason is important though: versioning.

One advantage of being an implementor is that I can play with languages that the Working Group didn't approve.

Today, the XML Processing Model Working Group published a new working draft. Not the very last working draft, but possibly very close.

Today, the XProc WG reached consensus on the last of the 126 issues submitted during our Candidate Recommendation period.

For the first time ever, (I assert) XML Calabash passes 100% of the XProc test suite!

Announcing a new release of XML Calabash, my XProc processor.

Constructing a “real world” XProc pipeline: building the XProc specification with XProc.

Today I'm releasing XML Calabash 0.9.0, the first beta release of my XProc processor.

I'm pleased to report that XProc: An XML Pipeline Language is now a W3C Candidate Recommendation.

I've been busy, ok?

The second “Last Call” for XProc ended on Friday. Things are looking good for progress to Candidate Recommendation. That means we need implementations!

I sincerely expect this to be the Last Call.

The XML Processing Model Working Group has published a new Working Draft of XProc: An XML Pipeline Language.

An AJAX/Google Maps hack. [Update 28 Mar 2008: Now with my Flickr contacts' photographs.]

The Working Group has agreed to adjust the XProc syntax one more time. One last time, I sincerely hope.

When are two versions better than one? Maybe never, but apparently sometimes two versions are an inevitable compromise.

If you don't plan for extensibility when you're designing version 1.0 of your language, you often don't get any. I think we have a plan for XProc now.

Part the ninth, in which we arrange for you to get in on the act.

Part the eighth, in which we get green lights across the board. Ok, it's a small board, but it's still a landmark.

The XML Processing Model Working Group has published XProc: An XML Pipeline Language as a Last Call Working Draft!

I've made another stab at the foundations for an XProc test suite. Coming soon: test validation and the ability to upload (and maybe some day run) your own tests.

Part the seventh, in which we (re)consider a fundamental part of the design.

The XML Processing Model Working Group has published a new Working Draft of XProc: An XML Pipeline Language.

Part the sixth, in which we consider options and parameters.

Part the fifth, in which we get the green light!

Part the fourth, in which we consider more buffering.

Baby steps beyond trivial examples and unit tests. (Look, ma, no make!)

Part the third, in which we consider looping.

The nascent XProc test suite is now on the web.

Part the second, in which we consider pipeline documents.

Part the first, in which we consider the heart of the problem.

In the intervening months since I first mentioned my plans to implement XProc, I've ripped it apart and started over twice. Third time, it seems, really is a charm.

I'll be speaking at XML Prague in June.

The XML Processing Model Working Group has published a new Working Draft of XProc: An XML Pipeline Language.

The XML Processing Model Working Group has published the second Working Draft of the pipeline language document.

The XML Processing Model Working Group has published the First Public Working Draft of the pipeline language document.

Three productive days with the XML Processing Model Working Group.

My XProc implementation successfully loaded and evaluated it's first pipeline without throwing an exception, hanging, or otherwise falling over. Pardon the melodramatic title, please.

The XML Processing Model Working Group has officially published its first document: XML Processing Model Requirements and Use Cases.
