Schematron News

The upcoming release of ISO Schematron (if ISO votes yes for it!) seems to be putting a fire under implementors.

Uche Ogbuji seems to have been the first implementer into
the pool with "http://uche.ogbuji.net/uche.ogbuji.net/tech/4Suite/scimitar/"
>Scimitar, his Python implementation.

Brian Ewins emailed about a rewrite of JAXEN optimized to support Schematron better in Java. Schematron seems to expose some particular performance issues that may be hidden by more "typical" stylesheets or document tests: I was told MS use or used Schematron as part of the regresion tests for MSXML for this reason.

Daniel Cazzulino has mentioned he has been working on ISO Schematron upgrades for Schematron.NET. Schematron.NET can be used with Mono as well as MS' .NET.

IBM have added Schematron to their Alphaworks technology Business Integration Information Conformance Statements.

I have not tested any of these, so I cannot say how well they conform to the draft ISO Schematron: I expect they are closer to Schematron 1.5 (the baseline pre-ISO version that people settled on).

I had missed that the Open GIS (Geographical Information Systems) people added Schematron as a constraint language to their Geography Markup Language.

Finally, the Schematron Love-In mail group has been down for the last two weeks, at the same time as I have also been down with with flu (or out-of-town doing some training). I am contacting Source Forge to figure out what happened, and I hope we can restore it ASAP. So apologies to Uche, Brian and anyone else with Schematron announcements in that time.
