Network Access to Multimedia Information
Status of this Memo
This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind. Distribution of this memo is unlimited.
This report summarises the requirements of research and academic network users for network access to multimedia information. It does this by investigating some of the projects planned or currently underway in the community. Existing information systems such as Gopher, WAIS and World-Wide Web are examined from the point of view of multimedia support, and some interesting hypermedia systems emerging from the research community are also studied. Relevant existing and developing standards in this area are discussed. The report identifies the gaps between the capabilities of currentlydeployed systems and the user requirements, and proposes further work centred on the World-Wide Web system to rectify this.
The report is in some places very detailed, so it is preceded by an extended summary, which outlines the findings of the report.
The first edition was released on 29 June 1993. This second edition contains minor changes, corrections and updates.
