|

First of all, thank you for taking the time to contribute to this project!
|
||||
|
||||
Before I can accept your contributions, I need a signed copy of the Individual Contributor License Agreement (ICLA) from you, which is available <a href="ICLA.txt">here</a>.
|
||||
|
||||
The ICLA is needed because it will allow me to dual license the OpenWebRX project under AGPL and a commercial license.
|
||||
I will also apply dual licensing to csdr, but only those parts that are original work (e.g. without the parts enabled by `-DUSE_IMA_ADPCM`; code taken from other projects is clearly separable).
|
||||
|
||||
However, even if there is commercial interest in the projects, I promise to keep them as open as possible, keeping my original intention to provide an open-source web-based SDR receiver software to the amateur radio operators and SDR enthusiasts.
|
||||
|
||||
This contributor agreement is based on the one of Apache Software Foundation, with some modifications.
|
||||
When you contribute for the first time, I will send you the ICLA. Replying with only the information requested and the text "I Agree" is sufficient.
|
||||
|
||||
Thanks,
|
||||
|
||||
Andras, HA7ILM

Individual Contributor License Agreement ("Agreement")
|
||||
|
||||
In order to clarify the intellectual property license granted
|
||||
with Contributions from any person or entity, András Retzler
|
||||
(hereinafter referred to as "Project Owner") must have a
|
||||
Contributor License Agreement ("CLA") on file that has
|
||||
been signed by each Contributor, indicating agreement to the license
|
||||
terms below. This license is for your protection as a Contributor as
|
||||
well as the protection of the Project Owner; it does not change your
|
||||
rights to use your own Contributions for any other purpose.
|
||||
Please read this document carefully before signing and keep a copy
|
||||
for your records.
|
||||
|
||||
Full name: ______________________________________________________
|
||||
|
||||
(optional) Public name: _________________________________________
|
||||
|
||||
Mailing Address: ________________________________________________

||||
|
||||
(optional) Telephone: ___________________________________________
|
||||
|
||||
E-Mail: ______________________________________________________
|
||||
|
||||
You accept and agree to the following terms and conditions for Your
|
||||
present and future Contributions submitted to the Project Owner.
|
||||
|
||||
Except for the license granted herein to the Project Owner and recipients
|
||||
of software distributed by the Project Owner, You reserve all right, title,
|
||||
and interest in and to Your Contributions.
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"You" (or "Your") shall mean the copyright owner or legal entity
|
||||
authorized by the copyright owner that is making this Agreement
|
||||
with the Project Owner. For legal entities, the entity making a
|
||||
Contribution and all other entities that control, are controlled
|
||||
by, or are under common control with that entity are considered to
|
||||
be a single Contributor. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"Contribution" shall mean any original work of authorship,
|
||||
including any modifications or additions to an existing work, that
|
||||
is intentionally submitted by You to the Project Owner for inclusion
|
||||
in, or documentation of, any of the products owned or managed by
|
||||
the Project Owner (the "Work"). For the purposes of this definition,
|
||||
"submitted" means any form of electronic, verbal, or written
|
||||
communication sent to the Project Owner or its representatives,
|
||||
including but not limited to communication on electronic mailing
|
||||
lists, source code control systems, and issue tracking systems that
|
||||
are managed by, or on behalf of, the Project Owner for the purpose of
|
||||
discussing and improving the Work, but excluding communication that
|
||||
is conspicuously marked or otherwise designated in writing by You
|
||||
as "Not a Contribution."
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this Agreement, You hereby grant to the Project Owner and to
|
||||
recipients of software distributed by the Project Owner a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare derivative works of,
|
||||
publicly display, publicly perform, sublicense, and distribute Your
|
||||
Contributions and such derivative works.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this Agreement, You hereby grant to the Project Owner and to
|
||||
recipients of software distributed by the Project Owner a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have
|
||||
made, use, offer to sell, sell, import, and otherwise transfer the
|
||||
Work, where such license applies only to those patent claims
|
||||
licensable by You that are necessarily infringed by Your
|
||||
Contribution(s) alone or by combination of Your Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If any
|
||||
entity institutes patent litigation against You or any other entity
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging
|
||||
that your Contribution, or the Work to which you have contributed,
|
||||
constitutes direct or contributory patent infringement, then any
|
||||
patent licenses granted to that entity under this Agreement for
|
||||
that Contribution or Work shall terminate as of the date such
|
||||
litigation is filed.
|
||||
|
||||
4. You represent that you are legally entitled to grant the above
|
||||
license. If your employer(s) has rights to intellectual property
|
||||
that you create that includes your Contributions, you represent
|
||||
that you have received permission to make Contributions on behalf
|
||||
of that employer, that your employer has waived such rights for
|
||||
your Contributions to the Project Owner, or that your employer has
|
||||
executed a separate Corporate CLA with the Project Owner.
|
||||
|
||||
5. You represent that each of Your Contributions is Your original
|
||||
creation (see section 7 for submissions on behalf of others). You
|
||||
represent that Your Contribution submissions include complete
|
||||
details of any third-party license or other restriction (including,
|
||||
but not limited to, related patents and trademarks) of which you
|
||||
are personally aware and which are associated with any part of Your
|
||||
Contributions.
|
||||
|
||||
6. You are not expected to provide support for Your Contributions,
|
||||
except to the extent You desire to provide support. You may provide
|
||||
support for free, for a fee, or not at all. Unless required by
|
||||
applicable law or agreed to in writing, You provide Your
|
||||
Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS
|
||||
OF ANY KIND, either express or implied, including, without
|
||||
limitation, any warranties or conditions of TITLE, NON-
|
||||
INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
|
||||
|
||||
7. Should You wish to submit work that is not Your original creation,
|
||||
You may submit it to the Project Owner separately from any
|
||||
Contribution, identifying the complete details of its source and of
|
||||
any license or other restriction (including, but not limited to,
|
||||
related patents, trademarks, and license agreements) of which you
|
||||
are personally aware, and conspicuously marking the work as
|
||||
"Submitted on behalf of a third-party: [named here]".
|
||||
|
||||
8. You agree to notify the Project Owner of any facts or circumstances of
|
||||
which you become aware that would make these representations
|
||||
inaccurate in any respect.
