Additionally, there is no particular restriction that the text and code have to be under different licenses; we can very well say that it is all under the same license if we want. For the license choice, why not be as liberal as possible? The general idea is that, if someone is posting to a wiki, then generally they are happy to have that content widely quoted, modified, and reused. If public domain does not make sense in our international context, surely there is something close, e.g. "I release this content for use for all purposes". Runners up might be the MIT or Scala licenses, which are close and are more commonly used. While the GFDL is the FSF's recommended license for documentation, significant problems with it have turned up. For your consideration, I'll append part of the statement put before Debian's members a while ago. In addition to the three problems this text identifies, note that GFDL content is not even compatible with GPL content. Draw your own conclusions about why the FSF, with all of its legal resources, might release such a license with these surprising properties. -Lex The full resolution is at http://www.debian.org/vote/2006/vote_001 . My comments are in [...] brackets. (2) How does it fail to meet Debian's standards for Free Software? The GFDL conflicts with traditional requirements for free software in a variety of ways, some of which are expanded upon below. As a copyleft license, one of the consequences of this is that it is not possible to include content from a document directly into free software under the GFDL. The major conflicts are: (2.1) Invariant Sections The most troublesome conflict concerns the class of invariant sections that, once included, may not be modified or removed from the documentation in future. Modifiability is, however, a fundamental requirement of the DFSG, which states: 3. Derived Works The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software. Invariant sections create particular problems in reusing small portions of the work (since any invariant section must be included also, however large), and in making sure the documentation remains accurate and relevant. [This is actually no big deal for the wiki; we could just say we have no invariant sections.] (2.2) Transparent Copies The second conflict is related to the GFDL's requirements for transparent copies of documentation (that is, a copy of the documentation in a form suitable for editing). In particular, Section 3 of the GFDL requires that a transparent copy of the documentation be included with every opaque copy distributed, or that a transparent copy is made available for a year after the opaque copies are no longer being distributed. For free software works, Debian expects that simply providing the source (or transparent copy) alongside derivative works will be sufficient, but this does not satisfy either clause of the GFDL's requirements. [I do not understand the subtleties here, but it sounds even more complicated than GPL's requirements about distributing source code. If we take our license choice seriously, then we would have to think carefully about, e.g., enabling printing of the wiki, how to make a stand-alone "transparent copy" for use when not net connected, how to deal with changes in the wiki's format should we ever change wiki software, and how to deal with stuff extracted from the wiki where we might want to transition to a new format for the "transparent copy". Would this be time well spent?] (2.3) Digital Rights Management The third conflict with the GFDL arises from the measures in Section 2 that attempt to overcome Digital Rights Management (DRM) technologies. In particular, the GFDL states that You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. This inhibits freedom in three ways: it limits use of the documentation as well as distribution, by covering all copies made, as well as copies distributed; it rules out distributing copies on DRM-protected media, even if done in such a way as to give users full access to a transparent copy of the work; and, as written, it also potentially disallows encrypting the documentation, or even storing it on a filesystem that supports permissions. [This has terrible implications. It seems to imply that if you send an encrypted email to someone, then you may not include any GFDL content. Hmm, in fact, 'GFDL "encrypted filesystem"' gets a lot of interesting Google hits.] |
