MathML and SVG

~1990 HTML

A dozen tags, some of which are defunct
Largely: headings, paragraphs, lists

... but what about...

1993: HTML+

~80

Math, and Graphics

What do you need in order to share research?

Math and Graphics

HTML 5

HTML 5:
These ones are special.

Math and Graphics

(MathML/SVG appear hundreds of times in html.spec.whatwg.org)

Unique Challenges

• Co-evolutionary solutions
• Under-specification by today's standards
• Another era of standards: "Contains much that is appocraphal or at least greatly exagerated."
• "Separate" and under-invested in resolving.

Let's make these things less special...

One Web.

SVG has a head-start here and another interesting challenge/opportunity

Nikolas will tell you about that - 

first, briefly... MathML

• Happening in a very active CG
• Recent TAG review
• Upstreaming in Chromium
• Currently working on WG charter

Informed by implementations, modern alignment - like SVG

Some good resolutions already in WebKit...

Currently 2323 Tests!

• Safari ~68%
• Firefox ~73%
• Chrome ~44%
• Igalia's  ~95%

We'd like to find ways to work better on some of the challenges that remain, even pre-WG because relaying significant gaps in context is especially inefficient.
