An important message from Norm Walsh:

Hello world,

As previously announced, the XProc community group will meet in
London, GB, on 10 and 11 June, 2019, immediately after the MarkupUK

I’ve updated the conference pages with more details:

If you are planning to attend, please (please!) add your name to the
attendees list on (If
you can’t edit that page, or don’t wish to, please send me an email or
open an issue and someone else will add your name.)

I need a complete attendee list by Monday, 3 June, in order to give
the building security enough time to register folks and get badges
printed. (Please bring ID with you.)

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.
