  375. Creative Commons Corporation (&quot;Creative Commons&quot;) is not a law firm and

  377. Creative Commons public licenses does not create a lawyer-client or

  384. Using Creative Commons Public Licenses
  385. Creative Commons public licenses provide a standard set of terms and
  386. conditions that creators and other rights holders may use to share
  387. original works of authorship and other material subject to copyright
  388. and certain other rights specified in the public license below. The
  389. following considerations are for informational purposes only, are not
  390. exhaustive, and do not form part of our licenses.
  391. Considerations for licensors: Our public licenses are
  392. intended for use by those authorized to give the public
  393. permission to use material in ways otherwise restricted by
  394. copyright and certain other rights. Our licenses are
  395. irrevocable. Licensors should read and understand the terms
  396. and conditions of the license they choose before applying it.
  397. Licensors should also secure all rights necessary before
  398. applying our licenses so that the public can reuse the
  399. material as expected. Licensors should clearly mark any
  400. material not subject to the license. This includes other CC-
  401. licensed material, or material used under an exception or
  402. limitation to copyright. More considerations for licensors:
  403. wiki.creativecommons.org/Considerations_for_licensors
  404. Considerations for the public: By using one of our public
  405. licenses, a licensor grants the public permission to use the
  406. licensed material under specified terms and conditions. If
  407. the licensor&#39;s permission is not necessary for any reason--for
  408. example, because of any applicable exception or limitation to
  409. copyright--then that use is not regulated by the license. Our
  410. licenses grant only permissions under copyright and certain
  411. other rights that a licensor has authority to grant. Use of
  412. the licensed material may still be restricted for other
  413. reasons, including because others have copyright or other
  414. rights in the material. A licensor may make special requests,
  415. such as asking that all changes be marked or described.
  416. Although not required by our licenses, you are encouraged to
  417. respect those requests where reasonable. More considerations
  418. for the public:

  426. granted the Licensed Rights in consideration of Your acceptance of
  427. these terms and conditions, and the Licensor grants You such rights in
  428. consideration of benefits the Licensor receives from making the

  434. arranged, transformed, or otherwise modified in a manner requiring
  435. permission under the Copyright and Similar Rights held by the
  436. Licensor. For purposes of this Public License, where the Licensed
  437. Material is a musical work, performance, or sound recording,
  438. Adapted Material is always produced where the Licensed Material is
  439. synched in timed relation with a moving image.

  484. the Licensor hereby grants You a worldwide, royalty-free,
  485. non-sublicensable, non-exclusive, irrevocable license to
  486. exercise the Licensed Rights in the Licensed Material to:
  487. a. reproduce and Share the Licensed Material, in whole or
  488. in part; and
  489. b. produce, reproduce, and Share Adapted Material.
  490. 2. Exceptions and Limitations. For the avoidance of doubt, where
  491. Exceptions and Limitations apply to Your use, this Public
  492. License does not apply, and You do not need to comply with
  493. its terms and conditions.
  494. 3. Term. The term of this Public License is specified in Section
  495. 6(a).
  496. 4. Media and formats; technical modifications allowed. The
  497. Licensor authorizes You to exercise the Licensed Rights in
  498. all media and formats whether now known or hereafter created,
  499. and to make technical modifications necessary to do so. The

  501. authority to forbid You from making technical modifications
  502. necessary to exercise the Licensed Rights, including
  503. technical modifications necessary to circumvent Effective
  504. Technological Measures. For purposes of this Public License,
  505. simply making modifications authorized by this Section 2(a)
  506. (4) never produces Adapted Material.
  507. 5. Downstream recipients.
  508. a. Offer from the Licensor -- Licensed Material. Every
  509. recipient of the Licensed Material automatically
  510. receives an offer from the Licensor to exercise the
  511. Licensed Rights under the terms and conditions of this
  512. Public License.
  513. b. No downstream restrictions. You may not offer or impose
  514. any additional or different terms or conditions on, or
  515. apply any Effective Technological Measures to, the
  516. Licensed Material if doing so restricts exercise of the
  517. Licensed Rights by any recipient of the Licensed
  518. Material.
  519. 6. No endorsement. Nothing in this Public License constitutes or
  520. may be construed as permission to assert or imply that You
  521. are, or that Your use of the Licensed Material is, connected
  522. with, or sponsored, endorsed, or granted official status by,
  523. the Licensor or others designated to receive attribution as
  524. provided in Section 3(a)(1)(A)(i).
  525. b. Other rights.
  526. 1. Moral rights, such as the right of integrity, are not
  527. licensed under this Public License, nor are publicity,
  528. privacy, and/or other similar personality rights; however, to
  529. the extent possible, the Licensor waives and/or agrees not to
  530. assert any such rights held by the Licensor to the limited
  531. extent necessary to allow You to exercise the Licensed
  532. Rights, but not otherwise.
  533. 2. Patent and trademark rights are not licensed under this
  534. Public License.
  535. 3. To the extent possible, the Licensor waives any right to
  536. collect royalties from You for the exercise of the Licensed
  537. Rights, whether directly or through a collecting society
  538. under any voluntary or waivable statutory or compulsory
  539. licensing scheme. In all other cases the Licensor expressly
  540. reserves any right to collect such royalties.
  541. Section 3 -- License Conditions.
  542. Your exercise of the Licensed Rights is expressly made subject to the
  543. following conditions.
  544. a. Attribution.
  545. 1. If You Share the Licensed Material (including in modified
  546. form), You must:

  548. with the Licensed Material:
  549. i. identification of the creator(s) of the Licensed
  550. Material and any others designated to receive
  551. attribution, in any reasonable manner requested by
  552. the Licensor (including by pseudonym if
  553. designated);
  554. ii. a copyright notice;
  555. iii. a notice that refers to this Public License;
  556. iv. a notice that refers to the disclaimer of
  557. warranties;
  558. v. a URI or hyperlink to the Licensed Material to the
  559. extent reasonably practicable;
  560. b. indicate if You modified the Licensed Material and
  561. retain an indication of any previous modifications; and
  562. c. indicate the Licensed Material is licensed under this
  563. Public License, and include the text of, or the URI or
  564. hyperlink to, this Public License.
  565. 2. You may satisfy the conditions in Section 3(a)(1) in any
  566. reasonable manner based on the medium, means, and context in
  567. which You Share the Licensed Material. For example, it may be
  568. reasonable to satisfy the conditions by providing a URI or
  569. hyperlink to a resource that includes the required
  570. information.
  571. 3. If requested by the Licensor, You must remove any of the
  572. information required by Section 3(a)(1)(A) to the extent
  573. reasonably practicable.
  574. 4. If You Share Adapted Material You produce, the Adapter&#39;s
  575. License You apply must not prevent recipients of the Adapted
  576. Material from complying with this Public License.
  577. Section 4 -- Sui Generis Database Rights.
  578. Where the Licensed Rights include Sui Generis Database Rights that
  579. apply to Your use of the Licensed Material:
  580. a. for the avoidance of doubt, Section 2(a)(1) grants You the right
  581. to extract, reuse, reproduce, and Share all or a substantial
  582. portion of the contents of the database;
  583. b. if You include all or a substantial portion of the database
  584. contents in a database in which You have Sui Generis Database
  585. Rights, then the database in which You have Sui Generis Database
  586. Rights (but not its individual contents) is Adapted Material; and
  587. c. You must comply with the conditions in Section 3(a) if You Share
  588. all or a substantial portion of the contents of the database.
  589. For the avoidance of doubt, this Section 4 supplements and does not
  590. replace Your obligations under this Public License where the Licensed
  591. Rights include other Copyright and Similar Rights.
  592. Section 5 -- Disclaimer of Warranties and Limitation of Liability.
  593. a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
  594. EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
  595. AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
  596. ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
  597. IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
  598. WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
  599. PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
  600. ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
  601. KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
  602. ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
  603. b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
  604. TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
  605. NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
  606. INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
  607. COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
  608. USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
  609. ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
  610. DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
  611. IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
  612. c. The disclaimer of warranties and limitation of liability provided
  613. above shall be interpreted in a manner that, to the extent
  614. possible, most closely approximates an absolute disclaimer and
  615. waiver of all liability.
  616. Section 6 -- Term and Termination.
  617. a. This Public License applies for the term of the Copyright and
  618. Similar Rights licensed here. However, if You fail to comply with
  619. this Public License, then Your rights under this Public License
  620. terminate automatically.
  621. b. Where Your right to use the Licensed Material has terminated under
  622. Section 6(a), it reinstates:
  623. 1. automatically as of the date the violation is cured, provided
  624. it is cured within 30 days of Your discovery of the
  625. violation; or
  626. 2. upon express reinstatement by the Licensor.
  627. For the avoidance of doubt, this Section 6(b) does not affect any
  628. right the Licensor may have to seek remedies for Your violations
  629. of this Public License.
  630. c. For the avoidance of doubt, the Licensor may also offer the
  631. Licensed Material under separate terms or conditions or stop
  632. distributing the Licensed Material at any time; however, doing so
  633. will not terminate this Public License.
  634. d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
  635. License.
  636. Section 7 -- Other Terms and Conditions.
  637. a. The Licensor shall not be bound by any additional or different
  638. terms or conditions communicated by You unless expressly agreed.
  639. b. Any arrangements, understandings, or agreements regarding the
  640. Licensed Material not stated herein are separate from and
  641. independent of the terms and conditions of this Public License.
  642. Section 8 -- Interpretation.
  643. a. For the avoidance of doubt, this Public License does not, and
  644. shall not be interpreted to, reduce, limit, restrict, or impose
  645. conditions on any use of the Licensed Material that could lawfully
  646. be made without permission under this Public License.
  647. b. To the extent possible, if any provision of this Public License is
  648. deemed unenforceable, it shall be automatically reformed to the
  649. minimum extent necessary to make it enforceable. If the provision
  650. cannot be reformed, it shall be severed from this Public License
  651. without affecting the enforceability of the remaining terms and
  652. conditions.
  653. c. No term or condition of this Public License will be waived and no
  654. failure to comply consented to unless expressly agreed to by the
  655. Licensor.
  656. d. Nothing in this Public License constitutes or may be interpreted
  657. as a limitation upon, or waiver of, any privileges and immunities
  658. that apply to the Licensor or You, including from the legal
  659. processes of any jurisdiction or authority.
