1) ACTION: Anita - will send out the message outlining what we did at
the TPAC. Will pass this through us for verification before it is sent
to all the X3D lists.
2) W3C Bug 8238: competing 3D model serializations.
http://www.w3.org/Bugs/Public/show_bug.cgi?id=8238
JohnS: Sent a request to Maciej Stachowiak (W3C) requesting
clarification on what he meant by:
"Tentatively, I would not be in favor of an X3D-specific mechanism in
the parser. X3D is not supported directly by UAs, and it's not clear
if it ever will be (since there are competing 3D model serializations
with similar or greater levels of traction)."
and
"... But it doesn't make me, as a UA implementor, feel more motivated
to add built-in parsing complexity for a feature to be implemented by
third-part code."
So far, no response from Maciej.
3) W3C Bug 8238: Sam Ruby and list of X3D Elements and Attributes.
http://www.w3.org/Bugs/Public/show_bug.cgi?id=8238
This list contains abstract types, MF and SF enumerations, and other
keywords that need not be captured by HTML5.
ACTION - Don - will autogenerate element and attribute lists from the
schema and send it along to the HTML5 wg, in response to bug 8238.
4) Case independent encoding of X3D.
Question: Should we have an encoding that closely matches HTML5?
If we do, HTML5 content model - our goal would be that if we have an
all lower case encoding that a parser that reads in a relaxed parsing
mode, we would promote the capitalization for the DOM model interaction.
Noted that in X3D, there are no ambiguities created by ignoring case;
eg, there are no conflicts for "Interpolator" and "interpolator".
Also noted that HTML5, case does not matter, but the DOM is case
sensitive.
ACTION: All - do we relax case on xml parsing in general. (background
- html5 is case insensitive; can we cut and paste)
ACTION: Johannes - x3dom.org, make parser relaxed in terms of case
sensitivity.
5) General access to HTML5 group minutes.
The minutes are sent to members of this group, and to the public-x3d
mailing list. They are also archived to the Web3D internal archives,
but should be easily located by the general public.
ACTION: JohnS - add wiki section, and add hypermail links to minutes.
------------------
NEXT WEEK: We should look into the Void element (comment 6 in bug 8238)
hint: only contained content in any element is javascript code in a
script node (Shaders, too)
