|
||
|
|
<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

|
|
<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>

<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

|
||
|
|
<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>
