Draft Charter 6/2/93 - mdw 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 - e.g., 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? The BOF is intended to test interest in the subject, to define issues that need resolving, and to see whether a working group can be formed to work on those issues.
