[comp.graphics] Graphics for frames and semantic networks

hughes@hrc63.UUCP (01/29/87)

We have some people developing a knowledge representation system who wish to 
implement a graphics based user interface which will support frame 
editing/displaying taxonomic hierarchy/semantic network editing/displaying etc.
The system is currently written in Franz Lisp Opus 42.16 on a Sun 2, 
but we hope to port to Common Lisp on a Sun 3 in the near future. The Lisp
should have an adequate interface to other languages such as 'c'. 
Does anyone know of a package (preferably in the public domain) which would 
ease the writing of such a UI, in particular allowing displaying/editing 
of hierarchies, networks and frames.
