GZigZag Home Page

  • 200-04-14: Name change and move away from SourceForge This project is now called Gzz. See the new home page.

  • 2002-03-08: Upcoming name change. Ted Nelson has asked us, due to trademark considerations, not to use the name GZigZag any more. We shall comply with this and will announce the new name shortly, as soon as we come up with it. Once we have the new name, we will release version 0.6.4 with most likely only the name changed.

  • 2002-03-07: News: GZigZag 0.6.3 is released. This is a stable release. We recommend that all users switch to using the 0.6.x series. For information on getting GZigZag, refer to the download page

  • 2001-10-09: Problem with 0.6.1 We've noticed that 0.6.1 doesn't work properly on JDK 1.3.0. This is due to Sun changing the method AWTEvent.consume() to protected. We will release 0.6.2, fixing this problem shortly. In the meantime, try 0.6.0 which does not have this problem. Additionally, for Linux glibc-2.2, note Sun's note about crashes in 1.3.0 and 1.3.1 : stack size must be limited.

  • 2001-10-01: Xanadu links between different cells quoting the same PDF file! We now have, in the default ZZ space that the current CVS rewrite (to be released as 0.8.0 Real Soon Now(tm)) some Xanadu model spans included from a foreign PDF file, and a visualization which shows the other cells which quote the same file.

    (Screenshot) Note that the screenshot is VERY wide (1023 pixels) so you may have to scroll to see the other side. There are three reduced-size PDF pages on the image, and the two on the right-hand side are shown only because they quote the same mediaserver block containing the same pdf file. No explicit connection was created between the cells!

    This has a momentous significance: whenever you write another comment on the same PDF file, they are all interconnected and never lost in the depths of the system somewhere. "Copying" bits of sources is equivalent to building a hyperstructure. All the hard work is finally starting to pay off - we are using this system ourselves to start putting together a good picture of hypermedia literature for ourselves.

Ted Nelson's ZigZag(tm) is a new way of putting information into computers, kind of a crossing between a database, a filesystem, a personal information manager and many others. And even that isn't sufficient to describe it: it's simply something new. The intention is to have some screenshots up here at some point but we haven't had the time yet.

GZigZag is an open-source free software project implementing ZigZag architecture. Ted Nelson's ZigZag trademark is used in the name GZigZag with permission.

GZigZag is hosted at SourceForge (see links in the margin), and of the features provided we use CVS, one mailing list (gzigzag-commits), there is another mailing list at Xanadu, and the task manager. The other features are currently not in use.

GZigZag is directed by Tuomas J. Lukka and implemented by him and others. You are welcome to join in, please read the documentation and talk to Tuomas at lukka@iki.fi.
