Subject: arXiv updates and MathML Intent

Hi everyone,

As of this morning, arXiv's experimental HTML pages are now using an intent attribute for the first  time. Namely, each math element is annotated with the ":literal" property.

":literal" values are the only reliable starting point for graduate level texts in STEM, where simple heuristics fail as often as they succeed (if that). They fit Louis' pragmatic stance of "just show me what the author has written", while also allowing more informed intent attributes to be deposited on the subtrees, when known.

Additional intent upgrades are interesting future work for arXiv - and LaTeXML. We would like to gradually enrich subtrees, whenever we have sufficient confidence we can infer the mathematical concepts.

These new attributes for arXiv are only starting to trickle in with the article batches announced daily. It will take a full regeneration of the collection to have them everywhere. That could happen near the end of 2025, maybe just in time for the MathML 4 CR phase. We'll see.

Here is one random recently announced article, to illustrate today's changes:

P.S. My regrets for tomorrow's WG meeting, I will be traveling.

Greetings,
Deyan
