XProc Roundup

Interest in XProc has really picked up recently, which is exciting to see.  Here's a roundup of some of the recent activity:

• XProc: Step by Step. Vojtech Toman (who's working on EMC's Calumet implementation) wrote a great introduction to XProc.  Calumet itself is scheduled to be released under a developer's license on June 15.  I don't use any of EMC's products, but it's encouraging that such a big player in the market is embracing XProc.
• XProc Tutorial.  Roger Costello updated his excellent tutorial.  It's a bit of a shame that it's in PowerPoint, but it's well organized and comes with several sample scripts.
• Why XProc Rocks.  Joel Amoussou talks about XProc and news publishing.
• XML Pipelines / XProc for bioinformatics. Pierre Lindenbaum describes an interesting use of XProc.

The XProc spec is tantalizingly close to making the transition to proposed recommendation, and all the recent (and positive) attention makes me optimistic that XProc will be a standard that's actually used in the real world.
