Microcosm is an open architecture hypermedia system in which documents
remain in their native format and link information is held in separate
link databases. This has facilitated the introduction of generic links
which, once authored from a text string to a destination anchor, may
be followed from any occurrence of the text string in any
document. The generic link provides substantial reductions in authoring
effort for large hypermedia systems, but the limitation of the generic
link to text string source anchors needed to be addressed.
This paper describes extensions to the Microcosm architecture to create
MAVIS, Microcosm Architecture for Video, Image and Sound, in which
generic links may be used from both text and non-text media. This
development makes it possible to navigate through non-text media using content
as the key and, through the facilities of the dynamic link,
content based retrieval is also available. Examples of content based
navigation with image, video and sound are presented.
