Summary For The Intent Meeting Of 3/5/2026
<https://cryptpad.fr/#cp-md-0-summary>Summary

The meeting focused on reviewing horizontal accessibility requirements and
discussing the upcoming charter renewal. The group reviewed privacy,
security, and accessibility checklists for MathML, with Neil presenting his
responses to these requirements. Paul shared an explainer document about
intent that needed updating with internationalization considerations. David
and Neil discussed exclusive properties in MathML, particularly regarding
table properties. The team agreed to focus their next charter on completing
MathML Core and Full specifications for recommendation status, with
maintenance activities as the only new work item. Moritz invited Paul to
present his Read Aloud project at the upcoming DMV conference in Constance
in September.

to MathML Converter Development

The team discussed the development of a LaTeX to MathML converter using
Claude, which successfully converted LaTeX input into MathML in about half
an hour. They noted that while the converter needs further polishing, it
represents a promising alternative to their existing LaTeX conversion
system, which uses Unicode Math for in-place editing but is cumbersome for
LaTeX input. The discussion highlighted the challenges of converting math
content from various formats, with Neil sharing experiences about poor
quality MathML output from open-source textbooks and David mentioning the
need to validate converters against actual user practices.

Accessibility Updates

The meeting covered several updates and announcements. Paul reported on the
validation of an eternal project called "Read Aloud Maths" to explore
applications of math tracks using LLMs and Math Cat in multiple languages.
David shared a press release from the PDF Association, highlighting the
inclusion of MathML tagging in PDF readers like Firefox, and mentioned
ongoing efforts to improve accessibility in PDF readers. Bert raised
concerns about the charter's expiration in a month, which Neil thought was
extended to October.

Charter Extension Discussion

The team discussed their charter extension and agreed to pursue a 2-month
extension followed by a new charter, as they would not meet the original
timeline. Bert will submit the extension request to his colleagues. Neil
shared updates on horizontal reviews, including privacy, security, and
accessibility checklists, and noted that Paul will update the intent
explainer with message format considerations. David and Neil reviewed
exclusive properties in MathML, deciding to restructure the table
properties into mutually exclusive groups. The team agreed their next
charter should focus on completing MathML Core and Full specifications for
recommendation status, with no new features, and Neil will draft this
charter for the next meeting. Moritz invited Paul to present his read-aloud
project at the DMV conference in Constance in September.
