XProc Workshop in London, June 11-12

There will be an XProc workshop in London on 11-12 June, immediately following Markup UK on 9-10 June. We’ll post more information as soon as it becomes available, both here and on Github.

And please – if you have any comments, suggestions, or use cases on the current XProc 3.0 draft, let us know. We hope to have a “candidate release” of the spec ready in the spring, with implementations of that release available in June.

Input Needed

Were you at XML Prague, listening to Gerrit and Achim present the XProc 3.0 draft and thinking we’ve missed something or are doing it wrong? Do you wonder about the usefulness of the XProc draft for your project? Is there something we should do that we aren’t doing? We want to hear from you:

  • Feedback to the drafts
  • Input, use-cases, proposals for steps dealing with non-XML documents
  • Questions, objections, cheers, …

XProc Workshop in Prague, 6-7/2

I’m happy to report that the XProc workshop in Prague (hosted by XML Prague – thanks!) on Feb 6-7 was a great success. We now have a roadmap that looks like this (borrowed from the XML Prague slides):

  • Specs split into three documents: core, (required) step library and (optional) step library
  • Last call draft (of the core spec) “this spring”
  • Core spec and step spec “candidate releases” ready by June
  • XML Calabash 2 and MorganaXProc 2 implementations commensurate with CR by June
  • Erik Siegel’s Programmer Reference for 3.0 also planned for June

For more detail on what was said and done, see our Github Wiki. For a summary, the slides presented at the conference also provide a terrific overview.
