4. Designation of Derivative Works and of Modified Works

The identifying designation of Derivative Work and of Modified Work must be different to the corresponding identifying designation of the Original Work. This means especially that the (root-level) name of a Modelica package under this license must be changed if the package is modified (besides fixing of errors, adding vendor specific Modelica annotations, using a subset of the classes of a Modelica package, or using another representation, e.g. a binary representation).

5. [reserved]

6. Provision of Source Code

Licensor agrees to provide You with a copy of the Source Code of the Original Work but reserves the right to decide freely on the manner of how the Original Work is provided. For the matter of clarity, Licensor might provide only a binary representation of the Original Work. In that case, You may (a) either reproduce the Source Code from the binary representation if this is possible (e.g., by performing a copy of an encrypted Modelica package, if encryption allows the copy operation) or (b) request the Source Code from the Licensor who will provide it to You.

7. Exclusions from License Grant

Neither the names of Licensor (including, but not limited to, University of California, Lawrence Berkeley National Laboratory, U.S. Dept. of Energy, UC, LBNL, LBL, and DOE), nor the names of any contributors to the Original Work, nor any of their trademarks or service marks, may be used to endorse or promote products derived from this Original Work without express prior permission of the Licensor. Except as otherwise expressly stated in this License and in particular in Sections 2 and 5, nothing in this License grants any license to Licensor's trademarks, copyrights, patents, trade secrets or any other intellectual property, and no patent license is granted to make, use, sell, offer for sale, have made, or import embodiments of any patent claims.

No license is granted to the trademarks of Licensor even if such trademarks are included in the Original Work, except as expressly stated in this License. Nothing in this License shall be interpreted to prohibit Licensor from licensing under terms different from this License any Original Work that Licensor otherwise would have a right to license.

8. Attribution Rights

You must retain in the Source Code of the Original Work and of any Derivative Works that You create, all author, copyright, patent, or trademark notices, as well as any descriptive text identified therein as an "Attribution Notice". The same applies to the licensing notice of this License in the Original Work. For the matter of clarity, "author notice" means the notice that identifies the original author(s).

You must cause the Source Code for any Derivative Works that You create to carry a prominent Attribution Notice reasonably calculated to inform recipients that You have modified the Original Work.

In case the Original Work or Derivative Work is not provided in Source Code, the Attribution Notices shall be appropriately displayed, e.g., in the documentation of the Derivative Work.

9. Disclaimer of Warranty

The Original Work is provided under this License on an "as is" basis and without warranty, either express or implied, including, without limitation, the warranties of non-infringement, merchantability or fitness for a particular purpose. The entire risk as to the quality of the Original Work is with You. This disclaimer of warranty constitutes an essential part of this License. No license to the Original Work is granted by this License except under this disclaimer.

10. Limitation of Liability

Under no circumstances and under no legal theory, whether in tort (including negligence), contract, or otherwise, shall the Licensor, the owner or a licensee of the Original Work be liable to anyone for any direct, indirect, general, special, incidental, or consequential damages of any character arising as a result of this License or the use of the Original Work including, without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses. This limitation of liability shall not apply to the extent applicable law prohibits such limitation.

11. Termination

This License conditions your rights to undertake the activities listed in Section 2 and 5, including your right to create Derivative Works based upon the Original Work, and doing so without observing these terms and conditions is prohibited by copyright law and international treaty. Nothing in this License is intended to affect copyright exceptions and limitations. This License shall terminate immediately and You may no longer exercise any of the rights granted to You by this License upon your failure to observe the conditions of this license.

12. Termination for Patent Action

This License shall terminate automatically and You may no longer exercise any of the rights granted to You by this License as of the date You commence an action, including a cross-claim or counterclaim, against Licensor, any owners of the Original Work or any licensee alleging that the Original Work infringes a patent. This termination provision shall not apply for an action alleging patent infringement through combinations of the Original Work under combination with other software or hardware.

13. Jurisdiction

Any action or suit relating to this License may be brought only in the courts of a jurisdiction wherein the Licensor resides and under the laws of that jurisdiction excluding its conflict-of-law provisions. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any use of the Original Work outside the scope of this License or after its termination shall be subject to the requirements and penalties of copyright or patent law in the appropriate jurisdiction. This section shall survive the termination of this License.

14. Attorneys' Fees

In any action to enforce the terms of this License or seeking damages relating thereto, the prevailing party shall be entitled to recover its costs and expenses, including, without limitation, reasonable attorneys' fees and costs incurred in connection with such action, including any appeal of such action. This section shall survive the termination of this License.

15. Miscellaneous

  1. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable.
  2. No verbal ancillary agreements have been made. Changes and additions to this License must appear in writing to be valid. This also applies to changing the clause pertaining to written form.
  3. You may use the Original Work in all ways not otherwise restricted or conditioned by this License or by law, and Licensor promises not to interfere with or be responsible for such uses by You.
  4. You are under no obligation whatsoever to provide any bug fixes, patches, or upgrades to the features, functionality or performance of the source code ("Enhancements") to anyone; however, if you choose to make your Enhancements available either publicly, or directly to Lawrence Berkeley National Laboratory, without imposing a separate written license agreement for such Enhancements, then you hereby grant the following license: a non-exclusive, royalty-free perpetual license to install, use, modify, prepare derivative works, incorporate into other computer software, distribute, and sublicense such enhancements or derivative works thereof, in binary and source code form.

How to Apply the Modelica License 2

At the top level of your Modelica package and at every important subpackage, add the following notices in the info layer of the package:

  • Licensed by The Regents of the University of California, through Lawrence Berkeley National Laboratory under the Modelica License 2 Copyright (c) 2009-2017, The Regents of the University of California, through Lawrence Berkeley National Laboratory.
  • This Modelica package is free software and the use is completely at your own risk; it can be redistributed and/or modified under the terms of the Modelica license 2, see the license conditions (including the disclaimer of warranty) here or at http://www.modelica.org/modelica-legal-documents/ModelicaLicense2.html.

Include a copy of the Modelica License 2 under <library>.UsersGuide.ModelicaLicense2 (use http://www.modelica.org/modelica-legal-documents/ModelicaLicense2.mo). Furthermore, add the list of authors and contributors under <library>.UsersGuide.Contributors or <library>.UsersGuide.Contact

For example, sublibrary Modelica.Blocks of the Modelica Standard Library may have the following notices:

  • Licensed by Modelica Association under the Modelica License 2 Copyright (c) 1998-2008, Modelica Association.
  • This Modelica package is free software and the use is completely at your own risk; it can be redistributed and/or modified under the terms of the Modelica license 2, see the license conditions (including the disclaimer of warranty) here or at http://www.modelica.org/modelica-legal-documents/ModelicaLicense2.html.

For C-source code and documents, add similar notices in the corresponding file.

For images, add a "readme.txt" file to the directories where the images are stored and include a similar notice in this file.

In these cases, save a copy of the Modelica License 2 in one directory of the distribution, e.g., http://www.modelica.org/modelica-legal-documents/ModelicaLicense2-standalone.html in directory <library>/help/documentation/ModelicaLicense2.html.
