Zigzag

Zigzag is a multi-dimensional data organizing system by Ted Nelson, the creator of the "hypertext" concept and the Xanadu project. Things are organized into cells like a spreadsheet, but without the rigid two-dimensional structure. Zigzag is currently implemented in Perl and distributed as shareware for $25.00 U.S.

    Release Notes: This version incorporates a variety of bugfixes and a major change to the API between the front-ends and the Zigzag.pm back-end. This has been changed from a "tied hash" to a more conventional function call interface, which should significantly improve portability to other programming languages in future. This also facilitated some changes to begin adding support for multiple datasets, aka "slices".
