MathML Refresh Community Group

MathML first became a W3C recommendation in 1998. It has wide support in the publishing industry and with assistive technology. MathML has had several updates, but is showing its age and needs to be updated. This group will focus on changes to the MathML 3 recommendation so that it better aligns with the current web environment, eases the burden on browser implementations, and increases support for assistive technology. The group will propose a new revision for MathML, potentially with profiles for browsers, publishers, and other subgroups such as authors or online tests. The group will also develop tests so that authors/publishers can be confident that what they see as an author is what the user will see as a reader when the same font is used. Participation is encouraged if you are in involved in publishing, authoring, or rendering math. The group strongly encourages the participation of those involved with browser implementations, recommendations, and APIs that potentially affect the rendering of math.

Note: Community Groups are proposed and run by the community. Although W3C hosts these conversations, the groups do not necessarily represent the views of the W3C Membership or staff.

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2019-01-15 by Neil Soiffer. The following people supported its creation: Bert Bos, Frédéric Wang, Moritz Schubotz, David Carlisle, Charles LaPierre, Daniel Marques, Neil Soiffer, Patrick D F Ion, Manuel Rego Casasnovas. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at site-comments@w3.org
