  337. Creative Commons Corporation (&quot;Creative Commons&quot;) is not a law firm and
  338. does not provide legal services or legal advice. Distribution of
  339. Creative Commons public licenses does not create a lawyer-client or
  340. other relationship. Creative Commons makes its licenses and related
  341. information available on an &quot;as-is&quot; basis. Creative Commons gives no
  342. warranties regarding its licenses, any material licensed under their

  344. disclaims all liability for damages resulting from their use to the

  346. Using Creative Commons Public Licenses
  347. Creative Commons public licenses provide a standard set of terms and
  348. conditions that creators and other rights holders may use to share
  349. original works of authorship and other material subject to copyright
  350. and certain other rights specified in the public license below. The
  351. following considerations are for informational purposes only, are not
  352. exhaustive, and do not form part of our licenses.
  353. Considerations for licensors: Our public licenses are
  354. intended for use by those authorized to give the public
  355. permission to use material in ways otherwise restricted by
  356. copyright and certain other rights. Our licenses are
  357. irrevocable. Licensors should read and understand the terms
  358. and conditions of the license they choose before applying it.
  359. Licensors should also secure all rights necessary before
  360. applying our licenses so that the public can reuse the
  361. material as expected. Licensors should clearly mark any
  362. material not subject to the license. This includes other CC-
  363. licensed material, or material used under an exception or
  364. limitation to copyright. More considerations for licensors:
  365. wiki.creativecommons.org/Considerations_for_licensors
  366. Considerations for the public: By using one of our public
  367. licenses, a licensor grants the public permission to use the
  368. licensed material under specified terms and conditions. If
  369. the licensor&#39;s permission is not necessary for any reason--for
  370. example, because of any applicable exception or limitation to
  371. copyright--then that use is not regulated by the license. Our
  372. licenses grant only permissions under copyright and certain
  373. other rights that a licensor has authority to grant. Use of
  374. the licensed material may still be restricted for other
  375. reasons, including because others have copyright or other
  376. rights in the material. A licensor may make special requests,
  377. such as asking that all changes be marked or described.
  378. Although not required by our licenses, you are encouraged to
  379. respect those requests where reasonable. More considerations
  380. for the public:

  384. By exercising the Licensed Rights (defined below), You accept and agree
  385. to be bound by the terms and conditions of this Creative Commons
  386. Attribution 4.0 International Public License (&quot;Public License&quot;). To the
  387. extent this Public License may be interpreted as a contract, You are
  388. granted the Licensed Rights in consideration of Your acceptance of
  389. these terms and conditions, and the Licensor grants You such rights in
  390. consideration of benefits the Licensor receives from making the
  391. Licensed Material available under these terms and conditions.
  392. Section 1 -- Definitions.
  393. a. Adapted Material means material subject to Copyright and Similar
  394. Rights that is derived from or based upon the Licensed Material
  395. and in which the Licensed Material is translated, altered,
  396. arranged, transformed, or otherwise modified in a manner requiring
  397. permission under the Copyright and Similar Rights held by the
  398. Licensor. For purposes of this Public License, where the Licensed
  399. Material is a musical work, performance, or sound recording,
  400. Adapted Material is always produced where the Licensed Material is
  401. synched in timed relation with a moving image.
  402. b. Adapter&#39;s License means the license You apply to Your Copyright
  403. and Similar Rights in Your contributions to Adapted Material in

  410. specified in Section 2(b)(1)-(2) are not Copyright and Similar
  411. Rights.
  412. d. Effective Technological Measures means those measures that, in the
  413. absence of proper authority, may not be circumvented under laws
  414. fulfilling obligations under Article 11 of the WIPO Copyright
  415. Treaty adopted on December 20, 1996, and/or similar international
  416. agreements.
  417. e. Exceptions and Limitations means fair use, fair dealing, and/or
  418. any other exception or limitation to Copyright and Similar Rights
  419. that applies to Your use of the Licensed Material.
  420. f. Licensed Material means the artistic or literary work, database,
  421. or other material to which the Licensor applied this Public
  422. License.
  423. g. Licensed Rights means the rights granted to You subject to the

  425. all Copyright and Similar Rights that apply to Your use of the
  426. Licensed Material and that the Licensor has authority to license.
  427. h. Licensor means the individual(s) or entity(ies) granting rights
  428. under this Public License.
  429. i. Share means to provide material to the public by any means or
  430. process that requires permission under the Licensed Rights, such
  431. as reproduction, public display, public performance, distribution,
  432. dissemination, communication, or importation, and to make material
  433. available to the public including in ways that members of the
  434. public may access the material from a place and at a time
  435. individually chosen by them.
  436. j. Sui Generis Database Rights means rights other than copyright
  437. resulting from Directive 96/9/EC of the European Parliament and of
  438. the Council of 11 March 1996 on the legal protection of databases,
  439. as amended and/or succeeded, as well as other essentially
  440. equivalent rights anywhere in the world.
  441. k. You means the individual or entity exercising the Licensed Rights
  442. under this Public License. Your has a corresponding meaning.
  443. Section 2 -- Scope.
  444. a. License grant.
  445. 1. Subject to the terms and conditions of this Public License,
  446. the Licensor hereby grants You a worldwide, royalty-free,
  447. non-sublicensable, non-exclusive, irrevocable license to
  448. exercise the Licensed Rights in the Licensed Material to:
  449. a. reproduce and Share the Licensed Material, in whole or
  450. in part; and
  451. b. produce, reproduce, and Share Adapted Material.
  452. 2. Exceptions and Limitations. For the avoidance of doubt, where
  453. Exceptions and Limitations apply to Your use, this Public
  454. License does not apply, and You do not need to comply with
  455. its terms and conditions.
  456. 3. Term. The term of this Public License is specified in Section
  457. 6(a).
  458. 4. Media and formats; technical modifications allowed. The
  459. Licensor authorizes You to exercise the Licensed Rights in
  460. all media and formats whether now known or hereafter created,
  461. and to make technical modifications necessary to do so. The
  462. Licensor waives and/or agrees not to assert any right or
  463. authority to forbid You from making technical modifications
  464. necessary to exercise the Licensed Rights, including
  465. technical modifications necessary to circumvent Effective
  466. Technological Measures. For purposes of this Public License,
  467. simply making modifications authorized by this Section 2(a)
  468. (4) never produces Adapted Material.
  469. 5. Downstream recipients.
  470. a. Offer from the Licensor -- Licensed Material. Every
  471. recipient of the Licensed Material automatically
  472. receives an offer from the Licensor to exercise the
  473. Licensed Rights under the terms and conditions of this
  474. Public License.
  475. b. No downstream restrictions. You may not offer or impose
  476. any additional or different terms or conditions on, or
  477. apply any Effective Technological Measures to, the
  478. Licensed Material if doing so restricts exercise of the
  479. Licensed Rights by any recipient of the Licensed
  480. Material.
  481. 6. No endorsement. Nothing in this Public License constitutes or
  482. may be construed as permission to assert or imply that You
  483. are, or that Your use of the Licensed Material is, connected
  484. with, or sponsored, endorsed, or granted official status by,
  485. the Licensor or others designated to receive attribution as
  486. provided in Section 3(a)(1)(A)(i).
  487. b. Other rights.
  488. 1. Moral rights, such as the right of integrity, are not
  489. licensed under this Public License, nor are publicity,
  490. privacy, and/or other similar personality rights; however, to
  491. the extent possible, the Licensor waives and/or agrees not to
  492. assert any such rights held by the Licensor to the limited
  493. extent necessary to allow You to exercise the Licensed
  494. Rights, but not otherwise.
  495. 2. Patent and trademark rights are not licensed under this
  496. Public License.
  497. 3. To the extent possible, the Licensor waives any right to
  498. collect royalties from You for the exercise of the Licensed
  499. Rights, whether directly or through a collecting society
  500. under any voluntary or waivable statutory or compulsory
  501. licensing scheme. In all other cases the Licensor expressly
  502. reserves any right to collect such royalties.
  503. Section 3 -- License Conditions.
  504. Your exercise of the Licensed Rights is expressly made subject to the
  505. following conditions.
  506. a. Attribution.
  507. 1. If You Share the Licensed Material (including in modified
  508. form), You must:

  510. with the Licensed Material:

  512. Material and any others designated to receive
  513. attribution, in any reasonable manner requested by
  514. the Licensor (including by pseudonym if
  515. designated);
  516. ii. a copyright notice;
  517. iii. a notice that refers to this Public License;
  518. iv. a notice that refers to the disclaimer of
