- Frequently Asked Questions about CNRI's legal policy regarding
- contributions to Python
-
- If you have a question that isn't answered here, please write
- <guido@python.org>
-
- Q. What are the legal requirements for contributions to Python?
-
- CNRI's lawyers recommend that we collect legal agreements for all new
- contributions. For small contributions, a simple two-paragraph note
- in the email containing the contribution suffices (see
- bugrelease.txt). For more substantial contribution, we require a
- mailed signed copy of a simple form (see wetsign.txt). We have tried
- to make the legal language as simple as possible.
-
- Q. Why does CNRI require this?
-
- In order to make it possible to protect Python against potential
- infringements. Other organizations that distribute free software do
- the similar things; for example, the GNU project requires a much more
- strongly worded form, assigning all copyrights to the Free Software
- Foundation, for all contributions to GNU software.
-
- Q. When is a contribution small enough to require only an email note?
-
- This is determined by us on a per-contribution basis. Up to 20 lines
- of patches typically qualify as small; however if you manage to do
- something truly spectacular in 20 lines or less we may ask you to send
- in the signature form anyway.
-
- Q. I have contributed to Python in the past. Should I sign and mail
- in a form now?
-
- Yes, please. We are in the process of getting wet signatures for all
- major contributions to Python up to now. If you contributed a module
- or more, we'll try to get in touch with you; you can save us the
- effort and mail us the signed form right away!
-
- Q. Do I have to accurately list everything I contributed?
-
- No. If you made multiple contributions in the past, it is sufficient
- to write in the form under "description" something like "everything
- I've contributed until <date>." If you continue to make
- significant contributions in the future, you can send us an update
- form using a similar formulation every once in a while.
-
- Q. Can I send in a form to cover all my future contributions?
-
- No. However it's okay if you send in a form, say, once a year,
- covering all your contributions from the last time you sent one in
- until the date you sign the new form.
-
- Q. Does the form protect me against copyright or patent infringement
- suits?
-
- If you infringe somebody's rights, no form in the world that you sign
- can protect you. The form only protects CNRI, because the act of
- collecting the forms shows that CNRI is doing "due diligence"
- regarding asserting the origin of contributions.
-
- Q. Does the form protect me against claims from damage resulting from
- use of my contribution?
-
- We have reluctantly added a paragraph wherein you disclaim all
- warranties etc. You may see this as some form of protection. However
- the law regarding such disclaimers is complicated and varies widely
- between states and countries, and the particular disclaimer used on
- the form may not cover you in all cases.
-
- Q. Does the form transfer my copyrights to CNRI?
-
- No. CNRI only gets certain non-exclusive rights. See the form for
- the exact list of rights.
-
- Q. If I don't sign, will my past contributions be removed from Python?
-
- That is up to CNRI's lawyers to decide.
