Meeting minutes

<norm> Regrets also from Elisa Beshero-Bondar who plans to join the CG but can't this week.

<norm> Elisa also writes: Would an ixml presentation at the end of this week be of interest to announce to the group? One of my seniors, Hadleigh Jae Bills, is presenting this Friday on her senior project–in which she applied ixml (after learning it in one week!) to a famous transliteration of the Voynich manuscript, to convert it (with an XSLT step afterwards) to TEI. Presentation date / time: Friday 5/1 @ 12:30pm Eastern Daylight Time: should be

<norm> at 5:30pm in London. Schedule details on how to join by Zoom registration: https://digit-psb.github.io/DIGIT-Works/

<norm> And also: The event starts at noon EDT (or 5pm London). The first two hours could be of interest as some other projects also applied ixml in the following hour from my Digit 210 class, just not so extensively as that first one.

invisiblexml/ixml#334

Norm is working on it. NEeds to talk to Tom about DNS issues

#310 Not possible to set priority on rules

invisiblexml/ixml#310

Norm: probably better to consider ordered choice rather than priority, for my experience

Bethan: context-free is not closed under intersection. Needs some thought

Bethan: not sure whther ordered choice changes the language. Might be subtle.

Steven: await discussion document

Pending discussion with W3C.

Norm: nothing much will happen until the plenary in Dublin later this year

<Steven> https://www.rfc-editor.org/rfc/rfc9535

alan: could we look at PEG grammars in IETF RFC9535

alan: this is JSONPath grammar and is getting some interest from the iXML videos

alan: the JSONPath working group considered their grammar is a PEG grammar

alan: will send the email discussing it

Alan: I'll look for some other RFCs that might be PEG
