We would like to invite you to attend the following OOPSLA demonstration.

Hope to see you in Portland.

   * Room A-109



Demo Abstract:

Devise Hypermedia (DHM) includes an object-oriented application 
framework for developing Dexter-based hypermedia systems as well as a 
number of example applications. Hypermedia systems built with the 
framework fulfils the Dexter Hypertext Reference Model, including 
multi-headed (n-ary) links with bi- and uni-directional traversal. 
In addition, a variety of composites are applied to implement 
GuidedTours, TableTops, browsers and to collect results from queries. 

DHM systems also support integration of third party applications. DHM 
systems can also be configured to support cooperative work, such as 
users' navigation and editing of shared materials. The cooperation 
support is based on object-oriented database (OODB) technology, and 
includes long term transactions, flexible locking and awareness 
notifications. 

The DHM framework is platform independent, and DHM system variants 
exist for Unix (Sun SPARC and HP), Macintosh and Windows/NT. The DHM 
framework provides generic classes for developing Dexter-based 
hypermedia systems, and it also supports tailoring systems already 
developed using the framework.

A system based on the DHM framework may provide the following features:

   * Atomic components for media such as: text, graphics, video.

   * A variety of composites used for GuidedTours, TableTops, browsers, 
     and collecting results from simple queries.
   
   * Integration with third party applications such as Microsoft Excel 
     on Macintosh.
   
   * Span-to-span links for text components, object-to-object links for
     graphics components.

   * Multi-headed (n-arity) links with bi- and uni-directional 
     traversal.
   
   * Cooperation support including long term transactions, flexible 
     locking and awareness notifications based on augmented OODB 
     technology.
   
   * Sharing of hypermedia networks ('hypertexts' in Dexter terms) 
     across hardware/OS platforms.
