[Incubator] Contributor agreements

[Cameron Shorter]

Rich, Eric,
Thank you for your clarifications.

Here are the facts as I see them:
1. Committers are reluctant to sign and fax a piece of paper.
2. In many cases, Coorporation Legal departments will not sign anything 
because they are too scared, can't see the value in wasting their time, ....
3. Projects want to keep committer's overhead to an absolute minimum to 
ensure we can capture patches from the widest audience possible.
4. A CLA has minimal legal value apart from showing a willingness by a 
project to keep the code clean of copywrite.
5. There is a desire amongst projects to keep our code clean (with 
regards to copywrite).
6. Projects and contributors are prepared to take SIMPLE measures to 
ensure the code remains copywrite free.
7. Projects may also want to assign copywrite to OSGeo - which will be 
decided on a project by project basis.

So, why don't we set up a simple process for vetting software.  I'd suggest.
1. Have each committer EMAIL their acceptance of the project's license 
to an email list for achieving.  Eg: "I confirm that I'm happy to commit 
my code under the LGPL license to the Mapbuilder project".
2. For any incoming library, we check that the stated license is 
compatible with our project's license and email results to an archieved 
email list.  "I've checked the license of the XXX library, and have 
decided that the Mozilla license can be imported into a LGPL library".

Eric Raymond (ESR) participated in the meeting and made several impassioned arguments against the proposed CLA requirement.  He offered to draft a proposed "position statement" for OSGeo against CLAs and IP review that reflects his thoughts.  With his permission, I have appended his draft statement below.

Let's address each of these, and then turn to ESR's specific points.

The CLA is the proposed mechanism for making that happen.  It grants a license to the foundation under the developer's IP rights to permit OSGeo to copy, modify and distribute the contributed code.

To effect this, a committer would include a licensing statement in each source file (i.e., a header saying "this software is licensed under the GPL" and referencing the license).  See, e.g., http://www.crynwr.com/cgi-bin/ezmlm-cgi?3:mss:2241:200008:mjagaiijfhdmomhabjpc

Is it easier to track compliance with this requirement each and every time a change is committed, or is it easier to simply have the developer sign a contributor agreement *once* as a condition to becoming a project contributor?
> 
> Second, the proposed CLA also grants an express patent license to OSGeo, which none of the licenses under which current foundation projects are offered do (Neither the GPL, LGPL or the MIT license contains an express patent license).  While some may argue that there is little risk that a project contributor would assert patent rights in the project code, several people have already asked Autodesk to clarify its grant of patent rights vis-à-vis MapGuide Open Source.  It stands to reason that if one contributor agrees to grant a patent license in connection with its contributions, all other contributors to the project should do so as well.

An important part of this process is educating contributors regarding the IP issues, and obtaining an affirmative declaration (under a CLA, for example) that the code they are contributing is theirs and theirs alone, or, if not, that they identify third party code in their submissions.  Thus, the CLA doesn't represent the entire due diligence process, but is an important part.

I will also concede that at some point the addition of process will reach a point of diminishing returns and stifle and/or kill collaborative development of the code.  However, I believe that having reasonable due diligence procedures for new contributions (including obtaining CLAs from contributors) is a better approach than sticking one's head in the sand and hoping that the code isn't tainted.  [note:  I am only talking here about copyright issues.  I agree with ESR that "benign ignorance" is better in the case of patents, given the perverse rule (http://www.internetnews.com/dev-news/article.php/3389071) that your awareness of a patent on which you may infringe can result in a finding of willfulness and the trebling of damages against you.]   As a prominent member of the PHP community recently stated, "When you have an
 anyone-can-commit-or-submit policy, you have no idea where the newly contributed code has come from." (http://netevil.org/node.php?nid=633&SC=1).

But they probably would be leery if, over time, the code could not be vouched for. In response, big open-source projects such as Linux, Apache and Mozilla have implemented rigid procedures so that they can attest to the origins of the code. In other words, the openness of open source does not necessarily mean it is anonymous. Strikingly, even more monitoring of operations is required in open source than in other sorts of businesses."

> 
> ESR concedes that there is no direct case law on this point, but relies by extension on case law relating to ownership of bulletin board postings.  While there is some case law on implied copyright licenses, and many commentators agree that a nonexclusive license can be implied by the conduct of the parties, it is always better whenever possible to obtain an express license and clearly define its terms, rather than relying on a court to grant a license by implication after-the-fact with unclear terms.  The "implied license" argument is generally trotted out only as a last resort in the event of a legal challenge; it should not be relied on if there is a chance to obtain an express license up front.

> 
> c) Requiring CLAs is a "trap" because it unwisely shifts the burden to the foundation to prove the IP is clean, rather than leaving the burden on a potential challenger.
> 
> Due diligencing the provenance of contributed code and obtaining CLAs does not shift any burden to the foundation.  Simply asking contributors to sign a CLA does not mean that the foundation has assumed some higher obligation to ensure code purity.  To be sure, this process may ferret out issues in the code, but it does so at a point in time when such issues can be more easily remedied.  When code is proferred for inclusion in a project, it hasn't yet been accepted.  Is it not better to ask at that point about the origin of the code rather than be forced to remove it at a later date in the face of a challenge (when it might be difficult to remove)?
> 
> ESR's analogy to willful patent infringement is similarly misplaced.  Patents are public documents that can be researched.  Lawyers generally advise against doing so because this can lead to a finding of willful infringement.  But copyrights need not be registered or made public.  Thus the CLA requirement as part of a due diligence process does not entail searching through some database of copyrights to verify non-infringement; rather, it seeks simply to ensure that the person submitting the code is the original author (and thus the copyright holder) of that code or has permission from the author.  This is a very different inquiry from asking whether the functions or ideas embodied in the code infringe on another's patent.
> 
> d) Mandating CLAs is bad for open source because their widespread adoption could somehow lead the courts to conclude that any code not contributed under a CLA is therefore tainted.
> 
> Regardless of how many open source projects use CLAs, it requires a olympian leap of logic to conclude that simply because someone contributed code without signing a CLA the code must therefore violate someone else's copyright.  As the present debate is demonstrating firsthand, many developers have very good reasons for not wanting to sign a CLA.  But I have yet to learn that a developer won't sign a CLA because she wants to commit misappropriated code.  I find it equally implausible that any court would create such a presumption.  In any event, even if ESR is right, I would argue that this genie is already out of the bottle.  Many of the most successful and/or prominent open source projects already require that contributors sign a CLA.  Run a Google search for contributor license agreements and you'll be presented with a veritable who's who of projects/organizations that require some form of agreement or certification from contributors:  Linux, Apache, Mozilla, Fedora, Ec
lipse, OSAF, FSF, Openoffice, etc.

> 
> I agree that too much process is bad, and too much *legal* process can be horrible.  But a principal goal of creating this foundation was to provide a more mature legal and IP regime under which open source geospatial projects are operated.  Just as you can't have your cake and eat it too, you can't have the benefits of that regime without some legal process.  And practically speaking, the experience of the other successful open source projects noted above refutes the notion that requiring a developer to sign a license agreement is a substantial barrier to participation or that it impedes success of the project.
> 
> In the end, each project will need to balance the benefits of a reasonable IP policy against the risks of chilling participation due to "blame the laywer" FUD.  As we know, many open source projects have struck this balance in favor of mandating CLAs for all contributors, and many have not.  For MapGuide Open Source at least, I will recommend that we go the route of established organizations like Apache and require that all project contributors sign a CLA.
