                      July 1993 IETF Meeting in Amsterdam

                               BOF Session on



   The above BOF is scheduled for 1930 to 2200 on Tuesday 13 July
   in Room H, RAI, Amsterdam.

   BOF Agenda:

     1. Introduction

     2. Identifying the issues

     3. Goals for future work

   One or two people have asked if they can formally present research
   projects, but it's not that sort of meeting.  As you can see from the
   abstract below, it is really oriented towards service development within
   the Internet.  If your research is relevant, please bring it up in the
   discussion, but there are no formal slots allocated for speakers within
   the BOF.

   If you are coming, you may wish to read [the summary of] a RARE report
   "Network Access to Multimedia Information".  You can fetch this by
   anonymous FTP from:

   Directory:  /pub/mmaccess
   Filenames:  report.doc    Report in Word for Windows 2 format (binary!)
          Report in Postscript form
               report.txt    Report in ASCII text form
               summary.doc   Summary in Word for Windows 2 format (binary!)
         Summary in Postscript form
               summary.txt   Summary in ASCII text form
               *.*.Z         Each of the above files run through Unix
                             compress program (binary!)

Here's the abstract of what will be discussed at the BOF.

                             BOF ABSTRACT

The ready availability of user-friendly multimedia authoring tools such
as Authorware Professional, Asymmetrix Multimedia Toolbook, Macromind
Director and many more, has stimulated much interest in multimedia
within the user community.  Sophisticated interactive multimedia
applications are being developed in many disparate subjects and for a
wide range of purposes.  Users are now beginning to ask us, as network
technologists, "how can I make my multimedia application available to
others across the network?".

In a parallel development, existing client-server network information
retrieval tools are being enhanced with multimedia handling features. 
Gopher+ for instance has been designed with multimedia data firmly in
mind.  The World Wide Web project is currently defining a new version of
its hypertext markup language, to be called HMML - HyperMedia Markup
Language - which includes multimedia support.

A third strand of activity is the emergence of network technologies
capable of carrying audio and video data across the network, initially
driven by multimedia conferencing applications.  Network technologies
such as ATM and protocols such as RTP are potentially capable of
handling isochronous multimedia data in an effective way. 

This BOF session will focus on issues which link these three strands. 
Particular questions to be addressed are:

* What are user requirements in terms of responsiveness, and what demands
  this places on the network and server system, and how these might
  be mitigated.

* The prospects for making existing interactive multimedia applications
  available over the network - eg by writing conversion tools from
  proprietary formats to a suitable open format.

* To what extent can existing network information retrieval tools such as
  Gopher, WWW, WAIS be used for sophisticated multimedia applications?
  What about the tools emerging from the research community such as
  AthenaMuse 2 (MIT), Microcosm (U of Southampton), HyperG (U of Graz)?
  Do we need another tool, or can we build on what we have?

* How can such tools be enhanced to take advantage of isochronous
  data streams?

* What relevance do standards such as HyTime and MHEG have?

* What are the security implications of providing interactive
  multimedia applications in an inter-enterprise environment?

The BOF is intended to test interest in the subject, to define issues
that need resoving, and to see whether a WG can be formed to work on
those issues.
