JCoSy

CoSy is/was a conferencing system (also collaboration system, communicative synergy, cooperative syncretism...) that I developed at the University of Guelph, and used by several universities and by BIX, N-MIX (in Japan), CIX (in the UK) and other commercial sites. I don't own the rights to CoSy, the last I heard they were at this site. Hence JCoSy

NEWS - January 18, 2000
It appears that University of Guelph and Softword are willing to release CoSy under the GPL. (Whether the most recent sources can be located, however, is another question.) This doesn't negate JCoSy, but will provide something more solid to build on (perhaps the server side, with JCoSy as a client).

More details as available.

JCoSy (for Java CoSy, until I find a better name) is a rewrite of CoSy in Java (the original was in C for Unix), with some enhancements that I've been wanting to add to the original (like the ability to draw graphics into messages along with text). It isn't complete yet, and it has been on the back burner for a year or so now, but lately there's been some interest expressed on the net so I'm reviving it.

NEWS - October 5, 2000
JCoSy is now available for download. However, what's available is pretty much just a snapshot of the development directory as of when I was last working on it. There's a set of class files that still work (here's a recent screenshot), and all the Java source files (licensed under the GPL). This doesn't include the NAPLPS stuff which is bundled separately, see below.
NAPLPS
JCoSy uses NAPLPS to allow graphics in messages, my Java NAPLPS decoder package is available for
download (naplps.tgz). The tarball includes a brief README, here is the online version.
Thanks for your patience, I'll try to answer any emailed questions. Meanwhile you might also want to look at the paper I wrote for BYTE about the CoSy message storage architecture.
