We do love an acronym-loaded title. In English this time: Socialtext, the leading enterprise wiki provider, just submitted a Common Public Attribution License to the Open Source Initiative. Socialtext, which ships under a Mozilla Public License + Attribution License, is the first of its kind to seek Open Source Initiative (OSI) Certification on top of all that. If you're suspicious about all this license mania, it merits mentioning that the Open Source Initiative is no mere gold star dispenser. The OSI certainly is slightly more than a community-appointed body that manages open source licensing. Creators of the Open Source Definition, their OSI certification process protects against free-wheeling licensing proliferation and adds structure and weight to the idea of "open source." Socialtext's Common Public Attribution License (CPAL) is based on the original MPL, with new provisions in Sections 14 and 15. They also permitted the use of splash screens. In summary, Section 14 provides for attribution based on the Adaptive Public License; Section 15 provides for a network use provision based on "External Deployment" found in the Apple Public License, Real Network Public License and the Open Software License. The license, provided they get it certified, can be used with any software licensed under the MPL or compatible with it. CPAL takes precedence when work is combined. It is neither compatible, nor equal to, the General Public License (GPL). Socialtext will also try to license core components under both CPAL and the Perl Artistic License. The SocialCalc Engine code, for example, will be released under the Artistic License 2.0. The Artistic License was written by the Perl Foundation. Socialtext's attempt to land an OSI nod for CPAL is a step forward in healing rifts in the open source community, a community which actually did unite in a dramatic stance against Microsoft recently. In other Socialtext-oriented news, last April the wiki-maker unveiled its Virtual Edition, which enables end users to try its software without making a big commitment in dollars or download time.
