Thank you for this detailed report.  It is great to hear that this work
is continuing.

It would seem that this activity can continue without the need to create
a new working group - that is a bunch of extra work that might slow things
down.  I hope we can simply continue these efforts as part of X3D Working
Group activities.  Special-focus meetings can continue to be scheduled
to support such work.  Please consider this possibility and discuss
further with Johannes.  For example, it might be better to first attract
more people and get some momentum before trying to get formal approval
as a separate working group.  We will be happy to support in either case,
so a proposal will also be welcome when you decide the time is right for
that step.

We look forward to reviewing this draft and helping to write it.
May I recommend that you start by describing goals and also
already-existing assets that would help pursue this problem.
This would be a good topic for email discussion, maybe first on the
x3d at web3D.org member list and then decide if it is appropriate for
the public list.

Perhaps our next Korea teleconference might focus on this topic?

Myeong Won Lee has built an extension schema for unit nodes and will post
it soon, along with updated examples and an updated units browser.  It will
appear on the X3D Physical Units wiki site:


We still need to begin work on an official draft X3D v3.3 schema.  Don will
be working on that when time permits.  Placeholder link added to


Myeong Won mentioned that she is also looking at units in the DICOM standard.
Probably we should ask the Web3D Medical working group to look at and comment
on the X3D Physical Units Proposal.  Dick, Leonard Daly and Michael Aratow
will be meeting with DICOM next week at the SPIE conference in San Diego.

Of possible related interest is a new OASIS technical committee:

>     6) Mobile X3D functions (Myeong Won Lee)
>     7) Geometric medical data (Kwan Hee Yoo)

No new information to add.

This all sounds great.  More information is available on the public wiki

This can occur
- as part of Web3D Symposium (which has a busy schedule)
- as Birds of a Feather (BOF) during SIGGRAPH itself (which is best approach)

Anita Havele is scheduling SIGGRAPH BOF meetings for Web3D Consortium.
I expect that she will be glad to schedule this BOF for you.

There will likely be a public Web3D Consortium Member Meeting at the
symposium, and they will want to have a short summary from the Korea Chapter
of all your many activities.

This is all OK.

Attendance is free for SIGGRAPH attendees (which requires a separate
registration).  http://www.siggraph.org/s2010

We are also wondering if the Korea chapter members would like to be
part of a Web3D booth on the SIGGRAPH show floor.  Once again our
Executive Director Anita Havele can provide details about this opportunity.
This is a good way for companies to show what they are doing.  Please
inform the Korea Chapter members about this possibility.

Both of these dates sound good, let's do both.  If possible, please focus
on the X3D learning topic for one meeting (preferably February 22-23) and
then all the other topics for March 8-9.

all the best, Don
