Socialtext, the first Wiki company, released Socialtext Open at the O'Reilly Open Source Convention (OSCON). This is the first open source wiki with a commercial venture as its primary contributor. Over 2,000 businesses run Socialtext Wiki products today as a hosted service or appliance.
Based on the same product, Socialtext Open is released under a standard open source license, and contains all of Socialtext's enterprise grade code as well as enterprise management and enterprise integration tools.
Socialtext's first commercial open source offering was Wikiwyg, an AJAX- based WYSIWYG editor. Last month Socialtext announced a partnership with Dan Bricklin to distribute and co-develop wikiCalc, the wiki spreadsheet, under an open source license.
Drawing from its Perl luminary roots, Socialtext releases all its products under a liberal OSI-compliant Mozilla Public 1.1 license. Socialtext will make other products on its roadmap available under this license and open its codebase to all users on a liberal and ongoing basis.
Socialtext also shared its Public Roadmap to help guide the developer community for the next three months. The roadmap includes a source code repository, Debian, Red Hat, SOAP and REST APIs, usability enhancements, and additional DBMS management beyond Postgres, starting with MySQL.
