XProc Workshop in London in June

The next XProc Next Community Group meeting will take place in London on 10-11 June 2019, right after the Markup UK conference. Just as last year, MarkLogic will host the meeting in their London, Bank, offices.

Watch this space and for more information when it becomes available. And in the meanwhile, have a think about XProc 3.0 use cases, especially those involving non-XML formats such as JSON, and let us know.

XProc Workshop, Prague, 5-6 February 2019

We’ll convene at University of Economics (the XML Prague venue), room NB 468, in the same building as the main conference, on 5 February at 10 AM. There are lifts and stairs in front of the cloak room. Use the lift to go to the 4th floor and follow the corridor on your right. NB 468 is almost at the end of the corridor.

Please add your name to the attendee list at if you plan to attend.

XML Prague 2019 XProc Workshop

It’s time to start planning for XML Prague on February 7–9 2019, so why not include an XProc two-day workshop, happening right before the conference on 5–6 February, in your travel plans? Just like last time, the conference will kindly provide us with a room for us at the conference site, the University of Economics (UoE) campus at nam. W. Churchilla 4, Prague.

More details will be posted here and at as soon as possible.

September Workshop in Leipzig

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, …

To find out more, participate in the effort or simply get in touch:

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.
