Topic: Status reports

Topic: New open issues

+ #332 Invisible XML media type

  https://github.com/invisiblexml/ixml/issues/332

+ #330 XML Namespace not referenced in iXML

  https://github.com/invisiblexml/ixml/issues/330

+ #329 Unicode version not referenced in the spec

  https://github.com/invisiblexml/ixml/issues/329

+ #310 Not possible to set priority on rules

  https://github.com/invisiblexml/ixml/issues/310

Topic: First Int’l Symposium on Invisible XML

Topic: Ambiguity umbrella topic

  It was suggested that “ambiguity” is at the root of a number of issues/topics including rule priorities, negation, the subtraction operator, etc. How do we want to organize the process for tackling these issues?

Topic: Perspectives on serialization

  NW proposes we merge #296. We can revisit in the future, but this PR has been waiting review for months.

  See https://github.com/invisibleXML/ixml/pull/296

  Preview: https://invisiblexml.org/pr/296/index.html
     Diffs: https://invisiblexml.org/pr/296/autodiff.html

Topic: Modularization

Possible discussion of some of the ideas presented in Steven’s MarkupUK paper. (I’d like to point to it, but the MarkupUK proceedings doesn’t seem to support doing that. At least, the frames version, which is the only version I can find, doesn’t.)

Topic: A subtraction operator

See https://github.com/invisibleXML/ixml/issues/249

Topic: Next meeting

Normal date and time for ixml meetings is every other Tuesday at 3 pm British Time, 4 pm Central European Time (15:00 UTC during winter time, 14:00 UTC during summer time)

On the usual schedule, the next meeting would be Tuesday, 9 December, at 15:00 UTC for one hour.

We plan to meet “off-schedule” the following Tuesday as well, 16 December, at 15:00 UTC to discuss the symposium submissions.

For the record: the current state of the minute-taking rota is:

+ John Lumley, 2025-09-30
+ Norm Tovey-Walsh, 2025-10-14
+ Steven Pemberton, 2025-11-11


                                        Be seeing you,
                                          norm
