request for guidance: centralized extensibility for HTML5 using X3D graphics

[Dear HTML5 chairs:  guidance requested.  Other responses welcome too,
cc: includes public-html and TPAC 2009 special-session participants]

Sam, Maciej, Paul:

In response to the November 2009 TPAC meeting's plenary debate, an
HTML5 working group presentation and subsequent guidance discussions,
the X3D working group has produced a detailed response describing
how X3D can be part of HTML5 in support of centralized extensibility,
similar to SVG and MathML.

The response document _HTML5 Recommendation Additions for X3D_ is online at

Some comments and amplifying information are available at

A javascript-based X3D player invokable from HTML content has been
produced to demonstrate how these capabilities can work together
closely.  It utilizes the WebGL layer provided in Minefield/Firefox
and Webkit/Safari/Chrome nightly builds, and also shows excellent
performance results.  Available at

We are also prepared to extend these leading browser implementations
to add open-source solutions for native UA rendering of X3D scenes
within compound HTML5+X3D documents.  Details at

Minutes from the Decentralized Extensibility in HTML5 session at
TPAC 2009 online at following address, have also cc:ed participants

So what's next?

Should the HTML5 working group choose to not proceed farther than
SVG and MathML with centralized extensibility, we remain interested
in showing proper decentralized extensibility for X3D in HTML5.  Again,
guidance regarding best practice would be needed from HTML5 group.

Thus we now are seeking guidance regarding how to best proceed.  There
has been little discussion of our proposal on the HTML5 list.  Should
this be raised as an ISSUE?  Would you like us available on one or more
weekly teleconferences, or private discussions?  We are standing by.

Thanks for your many efforts and for considering this formal request.

all the best, Don
