Strengths of Hyper-G
- Structured hypermedia: composition (even across server
boundaries), sequences, hierarchical navigation, focussed searches.
- Real hypermedia: text, image, audio, video, postscript,
and 3D models, including hyperlinks.
- Links stored in separate database: followable backwards,
local map, link consistency.
- Integrated full text and attribute search.
- User identification modes and groups.
- Access permissions on per collection and per document basis
(users -> authors).
- Hyper-G is r/w: clients can edit database contents
(not just browse), depending on access rights.
- Documents and collections can be given arbitrary symbolic
names.
- Multilinguality in data and interface.
- 3D models and visualisations.
- Document caching and replication.
