\"The_Modelica_License_2-outline\"></a>The Modelica License 2</h4> |
|
<p><strong>Preamble.</strong> The goal of this license is that Modelica |
|
related model libraries, software, images, documents, data files etc. can |
|
be used freely in the original or a modified form, in open source and in |
|
commercial environments (as long as the license conditions below are |
|
fulfilled, in particular sections 2c) and 2d). The Original Work is |
|
provided free of charge and the use is completely at your own risk. |
|
Developers of free Modelica packages are encouraged to utilize this license |
|
for their work.</p> |
|
<p>The Modelica License applies to any Original Work that contains the |
|
following licensing notice adjacent to the copyright notice(s) for this |
|
Original Work:</p> |
|
<p><strong>Licensed by <name of Licensor> under the Modelica |
|
License 2</strong></p> |
|
<p><strong>1. Definitions.</strong></p> |
|
<ol type=\"a\"> |
|
<li>"License" is this Modelica License.</li> |
|
<li>"Original Work" is any work of authorship, including |
|
software, images, documents, data files, that contains the above |
|
licensing notice or that is packed together with a licensing notice |
|
referencing it.</li> |
|
<li>"Licensor" is the provider of the Original Work who has |
|
placed this licensing notice adjacent to the copyright notice(s) for |
|
the Original Work. The Original Work is either directly provided by the |
|
owner of the Original Work, or by a licensee of the owner.</li> |
|
<li>"Derivative Work" is any modification of the Original |
|
Work which represents, as a whole, an original work of authorship. For |
|
the matter of clarity and as examples: |
|
<ol type=\"a\"> |
|
<li>Derivative Work shall not include work that remains |
|
separable from the Original Work, as well as merely extracting |
|
a part of the Original Work without modifying it.</li> |
|
<li>Derivative Work shall not include (a) fixing of errors |
|
and/or (b) adding vendor specific Modelica annotations and/or |
|
(c) using a subset of the classes of a Modelica package, and/or |
|
(d) using a different representation, e.g., a binary |
|
representation.</li> |
|
<li>Derivative Work shall include classes that are copied from |
|
the Original Work where declarations, equations or the |
|
documentation are modified.</li> |
|
<li>Derivative Work shall include executables to simulate the |
|
models that are generated by a Modelica translator based on the |
|
Original Work (of a Modelica package).</li> |
|
</ol> |
|
</li> |
|
<li>"Modified Work" is any modification of the Original |
|
Work with the following exceptions: (a) fixing of errors and/or (b) |
|
adding vendor specific Modelica annotations and/or (c) using a subset |
|
of the classes of a Modelica package, and/or (d) using a different |
|
representation, e.g., a binary representation.</li> |
|
<li>"Source Code" means the preferred form of the Original |
|
Work for making modifications to it and all available documentation |
|
describing how to modify the Original Work.</li> |
|
<li>"You" means an individual or a legal entity exercising |
|
rights under, and complying with all of the terms of, this |
|
License.</li> |
|
<li>"Modelica package" means any Modelica library that is |
|
defined with the |
|
"<code><strong>package</strong> <Name> ... <strong>end</strong> <Name>;</code>" |
|
Modelica language element.</li> |
|
</ol> |
|
<p><strong>2. Grant of Copyright License.</strong> Licensor grants You a |
|
worldwide, royalty-free, non-exclusive, sublicensable license, for the |
|
duration of the copyright, to do the following:</p> |
|
<ol type=\"a\"> |
|
<li> |
|
<p>To reproduce the Original Work in copies, either alone or as |
|
part of a collection.</p> |
|
</li> |
|
<li> |
|
<p>To create Derivative Works according to Section 1d) of this |
|
License.</p> |
|
</li> |
|
<li> |
|
<p>To distribute or communicate to the public copies of the |
|
<u>Original Work</u> or a <u>Derivative Work</u> under <u>this |
|
License</u>. No fee, neither as a copyright-license fee, nor as a |
|
selling fee for the copy as such may be charged under this License. |
|
Furthermore, a verbatim copy of this License must be included in |
|
any copy of the Original Work or a Derivative Work under this |
|
License.<br> |
|
For the matter of clarity, it is permitted A) to distribute or |
|
communicate such copies as part of a (possible commercial) |
|
collection where other parts are provided under different licenses |
|
and a license fee is charged for the other parts only and B) to |
|
charge for mere printing and shipping costs.</p> |
|
</li> |
|
<li> |
|
<p>To distribute or communicate to the public copies of a |
|
<u>Derivative Work</u>, alternatively to Section 2c), under |
|
<u>any other license</u> of your choice, especially also under a |
|
license for commercial/proprietary software, as long as You comply |
|
with Sections 3, 4 and 8 below.<br> |
|
For the matter of clarity, no restrictions regarding fees, either |
|
as to a copyright-license fee or as to a selling fee for the copy |
|
as such apply.</p> |
|
</li> |
|
<li> |
|
<p>To perform the Original Work publicly.</p> |
|
</li> |
|
<li> |
|
<p>To display the Original Work publicly.</p> |
|
</li> |
|
</ol> |
|
<p><strong>3. Acceptance.</strong> Any use of the Original Work or a |
|
Derivative Work, or any action according to either Section 2a) to 2f) |
|
above constitutes Your acceptance of this License.</p> |
|
<p><strong>4. Designation of Derivative Works and of Modified |
|
Works.</strong> 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).</p> |
|
<p><strong>5. Grant of Patent License.</strong> Licensor grants You a |
|
worldwide, royalty-free, non-exclusive, sublicensable license, under patent |
|
claims owned by the Licensor or licensed to the Licensor by the owners of |
|
the Original Work that are embodied in the Original Work as furnished by |
|
the Licensor, for the duration of the patents, to make, use, sell, offer |
|
for sale, have made, and import the Original Work and Derivative Works |
|
under the conditions as given in Section 2. For the matter of clarity, |
|
the license regarding Derivative Works covers patent claims to the extent |
|
as they are embodied in the Original Work only.</p> |
|
<p><strong>6. Provision of Source Code.</strong> 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.<br> |
|
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.</p> |
|
<p><strong>7. Exclusions from License Grant.</strong> Neither the names of |
|
Licensor, 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.<br> |
|
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.</p> |
|
<p><strong>8. Attribution Rights.</strong> 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).<br> |
|
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.<br> |
|
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.</p> |
|
<p><strong>9. Disclaimer of Warranty.<br></strong> <u><strong>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.</strong></u> 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.</p> |
|
<p><strong>10. Limitation of Liability.</strong> 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.</p> |
|
<p><strong>11. Termination.</strong> 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.</p> |
|
<p><strong>12. Termination for Patent Action.</strong> 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.</p> |
|
<p><strong>13. Jurisdiction.</strong> 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.</p> |
|
<p><strong>14. Attorneys' Fees.</strong> 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.</p> |
|
<p><strong>15. Miscellaneous.</strong></p> |
|
<ol type=\"a\"> |
|
<li>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.</li> |
|
<li>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.</li> |
|
<li>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.</li> |

|
<h6>Using or Distributing a Modelica <u>Package</u> under the Modelica |
|
License 2</h6> |
|
<p><strong>What are the main differences to the previous version of the |
|
Modelica License?</strong></p> |
|
<ol> |
|
<li> |
|
<p>Modelica License 1 is unclear whether the licensed Modelica |
|
package can be distributed under a different license. |
|
Version 2 explicitly allows that "Derivative Work" |
|
can be distributed under any license of Your choice, see examples |
|
in Section 1d) as to what qualifies as Derivative Work (so, |
|
version 2 is clearer).</p> |
|
</li> |
|
<li> |
|
<p>If You modify a Modelica package under Modelica License 2 |
|
(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), |
|
you must rename the root-level name of the package for your |
|
distribution. In version 1 you could keep the name (so, |
|
version 2 is more restrictive). The reason of this restriction |
|
is to reduce the risk that Modelica packages are available that |
|
have identical names, but different functionality.</p> |
|
</li> |
|
<li> |
|
<p>Modelica License 1 states that "It is not allowed to |
|
charge a fee for the original version or a modified version of the |
|
software, besides a reasonable fee for distribution and |
|
support". Version 2 has a similar intention for all |
|
Original Work under <u>Modelica License 2</u> (to remain free |
|
of charge and open source) but states this more clearly as |
|
"No fee, neither as a copyright-license fee, nor as a selling |
|
fee for the copy as such may be charged". Contrary to |
|
version 1, Modelica License 2 has no restrictions on fees |
|
for Derivative Work that is provided under a different license (so, |
|
version 2 is clearer and has fewer restrictions).</p> |
|
</li> |
|
<li> |
|
<p>Modelica License 2 introduces several useful provisions for |
|
the licensee (articles 5, 6, 12), and for the licensor |
|
(articles 7, 12, 13, 14) that have no counter part in |
|
version 1.</p> |
|
</li> |
|
<li> |
|
<p>Modelica License 2 can be applied to all type of work, |
|
including documents, images and data files, contrary to |
|
version 1 that was dedicated for software only (so, |
|
version 2 is more general).</p> |
|
</li> |
|
</ol> |
|
<p><strong>Can I distribute a Modelica package (under Modelica |
|
License 2) as part of my commercial Modelica modeling and simulation |
|
environment?</strong></p> |
|
<p>Yes, according to Section 2c). However, you are not allowed to |
|
charge a fee for this part of your environment. Of course, you can charge |
|
for your part of the environment.</p> |
|
<p><strong>Can I distribute a Modelica package (under Modelica |
|
License 2) under a different license?</strong></p> |
|
<p>No. The license of an unmodified Modelica package cannot be changed |
|
according to Sections 2c) and 2d). This means that you cannot |
|
<u>sell</u> copies of it, any distribution has to be free of charge.</p> |
|
<p><strong>Can I distribute a Modelica package (under Modelica |
|
License 2) under a different license when I first encrypt the |
|
package?</strong></p> |
|
<p>No. Merely encrypting a package does not qualify for Derivative Work and |
|
therefore the encrypted package has to stay under Modelica |
|
License 2.</p> |
|
<p><strong>Can I distribute a Modelica package (under Modelica |
|
License 2) under a different license when I first add classes to the |
|
package?</strong></p> |
|
<p>No. The package itself remains unmodified, i.e., it is Original Work, |
|
and therefore the license for this part must remain under Modelica |
|
License 2. The newly added classes can be, however, under a different |
|
license.</p> |
|
<p><strong>Can I copy a class out of a Modelica package (under Modelica |
|
License 2) and include it</strong> <u><strong>unmodified</strong></u> |
|
<strong>in a Modelica package under a</strong> |
|
<u><strong>commercial/proprietary</strong></u> |
|
<strong>license?</strong></p> |
|
<p>No, according to article 2c). However, you can include model, |
|
block, function, package, record and connector classes in your Modelica |
|
package under <u>Modelica License 2</u>. This means that your Modelica |
|
package could be under a commercial/proprietary license, but one or more |
|
classes of it are under Modelica License 2.<br> |
|
Note, a "type" class (e.g., type Angle = |
|
Real(unit="rad")) can be copied and included unmodified under a |
|
commercial/proprietary license (for details, see the next question).</p> |
|
<p><strong>Can I copy a type class or</strong> <u><strong>part</strong></u> |
|
<strong>of a model, block, function, record, connector class, out of a |
|
Modelica package (under Modelica License 2) and include it modified or |
|
unmodified in a Modelica package under a</strong> |
|
<u><strong>commercial/proprietary</strong></u> |
|
<strong>license?</strong></p> |
|
<p>Yes, according to article 2d), since this will in the end usually |
|
qualify as Derivative Work. The reasoning is the following: A type class or |
|
part of another class (e.g., an equation, a declaration, part of a class |
|
description) cannot be utilized "by its own". In order to make |
|
this "usable", you have to add additional code in order that |
|
the class can be utilized. This is therefore usually Derivative Work and |
|
Derivative Work can be provided under a different license. Note, this only |
|
holds, if the additional code introduced is sufficient to qualify for |
|
Derivative Work. Merely, just copying a class and changing, say, one |
|
character in the documentation of this class would be no Derivative Work |
|
and therefore the copied code would have to stay under Modelica |
|
License 2.</p> |
|
<p><strong>Can I copy a class out of a Modelica package (under Modelica |
|
License 2) and include it in</strong> <u><strong>modified</strong></u> |
|
<strong>form in a</strong> <u><strong>commercial/proprietary</strong></u> |
|
<strong>Modelica package?</strong></p> |
|
<p>Yes. If the modification can be seen as a "Derivative Work", |
|
you can place it under your commercial/proprietary license. If the |
|
modification does not qualify as "Derivative Work" (e.g., bug |
|
fixes, vendor specific annotations), it must remain under Modelica |
|
License 2. This means that your Modelica package could be under a |
|
commercial/proprietary license, but one or more parts of it are under |
|
Modelica License 2.</p> |
|
<p><strong>Can I distribute a "save total model" under my |
|
commercial/proprietary license, even if classes under Modelica |
|
License 2 are included?</strong></p> |
|
<p>Your classes of the "save total model" can be distributed |
|
under your commercial/proprietary license, but the classes under Modelica |
|
License 2 must remain under Modelica License 2. This means you |
|
can distribute a "save total model", but some parts might be |
|
under Modelica License 2.</p> |
|
<p><strong>Can I distribute a Modelica package (under Modelica |
|
License 2) in encrypted form?</strong></p> |
|
<p>Yes. Note, if the encryption does not allow "copying" of |
|
classes (in to unencrypted Modelica source code), you have to send the |
|
Modelica source code of this package to your customer, if he/she wishes it, |
|
according to article 6.</p> |
|
<p><strong>Can I distribute an executable under my commercial/proprietary |
|
license, if the model from which the executable is generated uses models |
|
from a Modelica package under Modelica License 2?</strong></p> |
|
<p>Yes, according to article 2d), since this is seen as Derivative |
|
Work. The reasoning is the following: An executable allows the simulation |
|
of a concrete model, whereas models from a Modelica package (without |
|
pre-processing, translation, tool run-time library) are not able to be |
|
simulated without tool support. By the processing of the tool and by its |
|
run-time libraries, significant new functionality is added (a model can be |
|
simulated whereas previously it could not be simulated) and functionality |
|
available in the package is removed (e.g., to build up a new model by |
|
dragging components of the package is no longer possible with the |
|
executable).</p> |
|
<p><strong>Is my modification to a Modelica package (under Modelica |
|
License 2) a Derivative Work?</strong></p> |
|
<p>It is not possible to give a general answer to it. To be regarded as |
|
"an original work of authorship", a derivative work must be |
|
different enough from the original or must contain a substantial amount of |
|
new material. Making minor changes or additions of little substance to a |
|
preexisting work will not qualify the work as a new version for such |
|
purposes.</p> |

<h6>Using or Distributing a Modelica <u>Document</u> under the Modelica |
|
License 2</h6> |
|
<p>This section is devoted especially for the following applications:</p> |
|
<ol type=\"a\"> |
|
<li> |
|
<p>A Modelica tool extracts information out of a Modelica package |
|
and presents the result in form of a "manual" for this |
|
package in, e.g., html, doc, or pdf format.</p> |
|
</li> |
|
<li> |
|
<p>The Modelica language specification is a document defining the |
|
Modelica language. It will be licensed under Modelica |
|
License 2.</p> |
|
</li> |
|
<li> |
|
<p>Someone writes a book about the Modelica language and/or |
|
Modelica packages and uses information which is available in the |
|
Modelica language specification and/or the corresponding Modelica |
|
package.</p> |
|
</li> |
|
</ol> |
|
<p><strong>Can I sell a manual that was basically derived by extracting |
|
information automatically from a Modelica package under Modelica |
|
License 2 (e.g., a "reference guide" of the Modelica |
|
Standard Library)?</strong></p> |
|
<p>Yes. Extracting information from a Modelica package, and providing it in |
|
a human readable, suitable format, like html, doc or pdf format, where the |
|
content is significantly modified (e.g. tables with interface information |
|
are constructed from the declarations of the public variables) qualifies as |
|
Derivative Work and there are no restrictions to charge a fee for |
|
Derivative Work under alternative 2d).</p> |
|
<p><strong>Can I copy a text passage out of a Modelica document (under |
|
Modelica License 2) and use it</strong> |
|
<u><strong>unmodified</strong></u> <strong>in my document (e.g. the |
|
Modelica syntax description in the Modelica Specification)?</strong></p> |
|
<p>Yes. In case you distribute your document, the copied parts are still |
|
under Modelica License 2 and you are not allowed to charge a license |
|
fee for this part. You can, of course, charge a fee for the rest of your |
|
document.</p> |
|
<p><strong>Can I copy a text passage out of a Modelica document (under |
|
Modelica License 2) and use it in</strong> |
|
<u><strong>modified</strong></u> <strong>form in my document?</strong></p> |
|
<p>Yes, the creation of Derivative Works is allowed. In case the content is |
|
significantly modified this qualifies as Derivative Work and there are no |
|
restrictions to charge a fee for Derivative Work under |
|
alternative 2d).</p> |
|
<p><strong>Can I sell a printed version of a Modelica document (under |
|
Modelica License 2), e.g., the Modelica Language |
|
Specification?</strong></p> |
|
<p>No, if you are not the copyright-holder, since article 2c) does not |
|
allow a selling fee for a (in this case physical) copy. However, mere |
|
printing and shipping costs may be recovered.</p> |
