WINTERP -- the OSF/Motif Widget INTERPreter -- is available via anonymous
ftp from ftp.x.org /contrib/devel_tools/winterp-2.XX.tar.gz (where XX=03
currently). You can also get a slightly older version (2.00) from the X
Consortium's X11r6 distribution. WINTERP is free software available under
the standard X Consortium non-restrictive copyright.

WINTERP introductory blurb:
In the past, we've demonstrated that WINTERP can be used for supporting
"smart" forms-based interfaces in an e-mail based groupware system called
STRUDEL. STRUDEL is "distributed" system, meaning that forms interpretation
and processing happens entirely on the "client side" since there is no

Extensible Electronic Conversation Toolkit. In David Marca and
Geoffrey Bock, editors, GROUPWARE: Software for Computer-Supported
Cooperative Work, IEEE Computer Society Press, 1992, pp. 505-518.
(originally, in proceedings Conference on Computer-Supported
Cooperative Work, Los Angeles, October 1990, pp. 93-104.)
Another example of WINTERP useage is EIT's HTML Multimedia Authoring

via the World Wide Web". In proceedings Groupware '94,
August 1994. San Jose, CA.
An on-line version of the above paper is available via the World-Wide-Web:

I've been thinking about embedding WINTERP into Mosaic such that you can
have real user interfaces in place of Mosaic forms and hairy CGI scripts;
furthermore, you could use WINTERP's graphics/animation widget to create
dynamic, animated interfaces, "smart" image mapping, etc.
Embedding WINTERP in Mosaic is pretty easy, since they're both just Motif
programs sharing the same Xt event loop. Slightly harder, but still pretty
easy is getting WINTERP-generated widgetry to display in-line. The hardest
part is security. Obviously, to make something like this useable, you want
to either make the UI "applet" language safe and secure (a la safe-TCL), or
make use of secure HTTP to authenticate any "applet" programs running on
the client side.
Unfortunately, I don't have much time to work on stuff like that since I'm
spending my full 110% trying to get the aforementioned WWW authoring
environment to beta....
However, I'd be happy to give people pointers on embedding WINTERP into
Mosaic, since I don't have time to do it myself.
