.:: Conformance to the OSD ::.
(This section is not part of the Open Source Definition.)
We think the Open Source Definition captures what the great majority
of the software community originally meant, and still mean, by the
term "Open Source". However, the term has become widely used and
its meaning has lost some precision. The OSI
Certified mark is OSI's way of certifying that the license
under which the software is distributed conforms to the OSD; the
generic term "Open Source" cannot provide that assurance, but we
still encourage use of the term "Open Source" to mean conformance to
the OSD. For information about the OSI Certified
mark, and for a list of licenses that OSI has approved as conforming
to the OSD, see the OSD Certification Mark page.
