Gary & All,
MARC has developed standards for all of the items you discuss. The =
exciting thing since 1997 is that the MARBI committee has moved to =
format integration. This allows all of us to address both the digital =
nature and the traditional visual nature of newer formats. The real =
work of delineating the various materials formats you discuss takes =
place in the leader fields. The 06, 07, 08 tags especially. For =
example subfield g represents any projected medium. It is then further =
broken down by visual materials position 16 that allows us to specify =
anything from alpha character p for microscopic slide to alpha character =
v for video recording. One can then encode the computer nature of =
various formats with mdf designations (machine readable data file) or =
designate position 9 to specify the type of computer file as alpha =
character j for online system or service to i for interactive =
multimedia. For video streaming you can even designate the source of =
the signal.

Well, once again I have illustrated my weird cataloguer's personality. =
I guess I just feel that the developers of MARC are a really receptive =
group and the MARBI committee allows all of us to give input through =
representatives. What's great is that MARC is actually a very elegant =
classification system that is changing as I write this (Disclaimer in =
case of any errors ;-)) - never allowing itself to become static. It is =
complex, however, and perhaps the following web sites will help. The =
first is the Online Audiovisual Catuloguers site. The second is that of =
the proposed changes and discussions of MARBI format recommendations. =
They discuss all kinds of neat things like remote sensing images in 07 =
and hypertext links with URL's, URN's and URI's imbedded in MARC =
documents.

While most of the suggestions come from major groups like the OCLC =
Metadata Workshop, Dublin Core & LC, they also take recommends from =
individual software developers, etc.

Hope this helps,
