[M4IF Technotes] Standard for content-description

[Mikael Bourges-Sevenier]

Dear Sebastian,
XMT is the only textual format recognized by MPEG-4. It is primarily
intended for authoring.
The other formats are there for historical reasons: BT, scene+script etc.
are proprietary extensions of VRML 2.0 format but do not conform to VRML
syntax. Because of these incompatibilities and for other goodies provided by
XML, XMT was developed. For the little history, XMT is based on X3D
compromise DTD, which is nothing else than VRML 2.0 in XML...
Kind regards,
Mike

Hello
There are different formats for textual scenedescription, XMT,
scene+script/mux and bt-format. XMT is defined in standard, but what's with
the other formats? They are standardized or not? If yes, in what paper can I
find Informations about?
best regards
Sebastian
