Both GUIDE and Emacs Info are based on browsing static collections of
text. An author creates a hypertext document (e.g. a manual), using
some form of document language to set up links, create document
structure, etc. A reader can then browse the document using the links.

You cannot add links dynamically, based on your own ideas of
information relations, say. Neither can you use these systems to
create database-like systems, the way you do in HyperCard.

I would really like to see a dynamic hypertext system for unix,
possibly based on a network server...

INFO is very nice for browsing documentation, by the way. Much better
than standard unix manual-pages.

Guide on UNIX is the original version from U of Edinborough (sp),
which is different from the Mac version.  The Mac one does allow you
to create links dynamically.

NoteCards is availible under UNIX (from ENVOS Corp.) and also allows
completely dynamic link creation either by the user or under program
control (if you're not Lisp paranoid).

I posit that the reason the folks on comp.sys.hypercard spend all of
their time talking about programming problems is their limited
language, HyperTalk.

Does anybody know if the KMS system can run at least minimally from
ASCII terminals?  I requested info on it for Suns and from the
literature it looks like it requires a console.  Most of our users log
into Suns from microcomputers and don't have consoles.  If they could
still access the info in KMS (without windows, etc), it could be useful
to us.

Thanks in advance.

Apple Computer is one of the larger sponsors of the InterMedia project
at Brown University.  I suppose that at some point they're likely to
release it out on their higher end workstations.

There's an interesting story behind this which goes something like
this: Brown ported MacApp or some portion of the Mac toolbox calls
onto UNIX to support their development of IM.  Intermedia now depends
heavily on this code.  Apple is one of a consortium of sponsors for
IM.  The sponsors have varying rights to the resulting code.  For
Apple this is a drag because they don't have exclusive proprietary
rights (unless this has changed).  I wonder if Apple has required the
other sponsors to separately license from them the user interface
technology used in Intermedia?  That could give Apple a strong
position.

Apple's problem will be integrating embedded editors with its existing
toolbox in a compatible way, in addition to allowing compound
documents, although the latter could be acheived by substructuring
text forks.

Systems like InterMedia (or ENVOS NoteCards) are to HyperCard as
Microsoft Write is to Microsoft Word, or Assembly language is to
Modula-3.  Unfortunately these kind of relations make it hard to
provide upward compatibility, since one tends to hook deeply into low
level systems like HyperCard to accomplish the things that are
missing.

Perhaps we'll have a division of the Hypertext market into entry level
and professional tools.  Remember that in a few years Apple's next
generation OS and tools like Intermedia will make the current toolbox
and HyperCard look like the Apple // tools seem to us today.

I called IRIS regarding Intermedia last year.  They indicated that if
I wanted to find out more I would have to join IRIS and pay about
$10,000.  That is for state of the art info, there were several papers
published on Intermedia a while ago.  You'd probably have better luck
in a library actually.

PS- MacWeek contains the rumor that Apple and Brown will announce a
co-marketing agreement for Intermedia at a Dallas show next month.
The software will be provided without any customer support and only
under A/UX.  If its true this is an interesting dip of toe in the water.

No.  The Mac and PC versions of guide are marketed by OWL, who are
based in Edinburgh.

The UNIX version of guide was developed here at the University of Kent
at Canterbury by Prof. Peter Brown and is available, for a modest sum,
for the Sun3 (SunView or X11) and VAXstations (Ultrix+X11).  For more
details contact Judith Farmer, The Computing Laboratory, The University,
Canterbury, Kent CT2 7NF, ENGLAND, or e-mail me.
