Deephaven Community License Agreement Version 1.0
ACCEPTANCE. This Deephaven Community License Agreement is entered into by and between Deephaven Data Labs LLC, a Delaware Limited Liability Company, with an address of 2800 Niagara Lane North, Plymouth, MN 55447 ("Deephaven") and “You” (a) in your individual capacity, or (b) on behalf of your company if you are licensing the Software for a company for which or with which you work. By using the Software, You agree to all of the terms and conditions in this Deephaven Community License Agreement (the "Agreement").
THE SOFTWARE. The "Software" means the version of the Deephaven Community Software provided to the original licensee with this Agreement. The Software may include third party owned code. Each third party module is subject to the terms of its respective license; the details of which can be found in the notices served at https://github.com/deephaven/deephaven-core. Since licensees may contribute back to the Software as provided for in Section 3(b), the Software may include any such contributions.
GRANT OF LICENSE. Subject to the terms and conditions of this Agreement, Deephaven hereby grants You a royalty-free, worldwide, non-exclusive, non-transferable license to the Software (the "License"), subject, in all of the cases, to applicable laws and regulations, but not for the Prohibited Use (as provided for in Section 4), solely as follows:
a. Internal Use. A license to use, copy, compile, and install the Software for Your internal use;
b. Derivative Works. A license to (i) prepare, develop, compile, and test Derivative Works of the Software, (ii) use Your Derivative Works for Your internal use solely as expressly permitted in Section 3(a), and (iii) distribute Your Derivative Works back to Deephaven under a separate Deephaven Contributor Agreement for potential incorporation into the Software at Deephaven's sole discretion. A "Derivative Work" means any work that (A) is based on or derived from the Software including any modifications to the Software, or (B) meets the definition of derivative work under the United States Copyright Act of 1976, 17 U.S.C. Section 101; and
c. Distribution and redistribution. A license to distribute or redistribute the Software and Your Derivative Works, and copies of the Software and Your Derivative Works, to customers and other third parties for their use pursuant to this Agreement subject to the prohibitions in Section 4 and Agreement requirement as provided for in Section 5.
PROHIBITED USE. Notwithstanding any provision of this Agreement to the contrary, the original licensee is prohibited from using, distributing, or deploying the Software or Derivative Works in such a way that a third party (including any recipient under Section 3(c)) can, directly or indirectly through the original licensee, its agents, its technology, or solutions made available to them, add, define, redefine, or modify the schema for any input tables (including source tables, or other input objects) that the Software or Derivative Works access. For clarification, every recipient of the Software or Derivative Works after the original licensee of the Software is prohibited from adding, defining, redefining, or modifying the schema for any input tables (including source tables, or other input objects) that the Software or Derivative Works access. This prohibition in no way affects the ability of a third party to add, define, redefine, or modify the schema of output tables (including output tables that are interim or derived). Further, this prohibition in no way affects the ability of a third party to add, define, redefine, or modify data (as opposed to schema), nor does it cause You to be limited in any capacity for Your internal use as permitted in Section 3(a). If You have any questions on this prohibition, please contact us at: [email protected]
AGREEMENT. If You distribute the Software, whether directly, as a copy, or via Your Derivative Works you must provide recipients a copy of this Agreement (which will bind each recipient directly) and You must ensure that all copyright, patent, trademark, and attribution notices from the Software are retained.
AFFILIATES. You may permit Your affiliates to exercise the License, provided that such exercise must be solely for Your benefit and/or the benefit of Your affiliate, and You shall be responsible for all acts and omissions of such affiliates in connection with such exercise of the License, including but not limited to breach of any terms of this Agreement.
SUBLICENSE. The License is sublicensable only to Your third-party subcontractors and contractors performing services on Your or Your affiliates' behalf, subject to the terms and conditions of this Agreement. The License is not sublicensable to any other third party nor is it further sublicensable. You shall be responsible for all acts and omissions of such subcontractor and contractors in connection with such exercise of the sublicense, including but not limited to breach of any terms of this Agreement.
PATENTS. Rights to use the Software do not give You any right to implement or use Deephaven's patents independently of the permitted use of the Software.
RESERVATION OF RIGHTS. Deephaven reserves all rights not granted in this Agreement. You have no right to use Deephaven trade names, trademarks, service marks, or product names except as required for reasonable and customary use in describing the origin of the Software.
DISCLAIMER OF WARRANTY. THE SOFTWARE IS LICENSED ON AN "AS IS" BASIS WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND. DEEPHAVEN DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY, OR FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of using, distributing or redistributing the Software and Derivative Works and assume all risks associated with Your exercise of the License.
INDEMNIFICATION. If You distribute or redistribute the Software or Derivative Works, You agree to defend on request, and indemnify, Deephaven and its affiliates, officers, directors, employees and agents from and against any and all losses, damages, liabilities, claims, costs and expenses (including reasonable attorney’s fees and expenses) incurred or arising from the exploitation of the Software or Derivative Works.
LIMITATION OF LIABILITY. THE LICENSE IS GRANTED FOR NO FEE. IN NO EVENT AND UNDER NO LEGAL THEORY, WHETHER IN TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL DEEPHAVEN BE LIABLE FOR ANY DAMAGES ARISING OUT OF OR AS A RESULT OF THIS AGREEMENT, INCLUDING ANY DIRECT, INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES (INCLUDING BUT NOT LIMITED TO DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR LOSS OR CORRUPTION OF DATA), EVEN IF DEEPHAVEN HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
TERMINATION. The License will automatically terminate if You violate the use rights or prohibitions in this Agreement.
GOVERNING LAW. This Agreement will be interpreted, construed and enforced in all respects in accordance with the laws of the State of Delaware, USA without reference to its choice of law rules to the contrary.
TL:DR; The Deephaven Community License Agreement is similar to licenses from other open-core companies. It has a single restriction on what third parties can do, but is otherwise broadly permissive.
