Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are
not exhaustive, and do not form part of our licenses.

	Considerations for licensors: Our public licenses are intended
	for use by those authorized to give the public permission to
	use material in ways otherwise restricted by copyright and
	certain other rights. Our licenses are irrevocable. Licensors
	should read and understand the terms and conditions of the
	license they choose before applying it. Licensors should also
	secure all rights necessary before applying our licenses so
	that the public can reuse the material as expected. Licensors
	should clearly mark any material not subject to the license.
	This includes other CC-licensed material, or material used
	under an exception or limitation to copyright. More
	considerations for licensors:

	Considerations for the public: By using one of our public
	licenses, a licensor grants the public permission to use the
	licensed material under specified terms and conditions. If
	the licensor's permission is not necessary for any reason?for
	example, because of any applicable exception or limitation
	to copyright?then that use is not regulated by the license.
	Our licenses grant only permissions under copyright and
	certain other rights that a licensor has authority to grant.
	Use of the licensed material may still be restricted for
	other reasons, including because others have copyright or
	other rights in the material. A licensor may make special
	requests, such as asking that all changes be marked or
	described. Although not required by our licenses, you are
	encouraged to respect those requests where reasonable.

By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution 4.0 International Public License ("Public License"). To the
extent this Public License may be interpreted as a contract, You are
granted the Licensed Rights in consideration of Your acceptance of these
terms and conditions, and the Licensor grants You such rights in
consideration of benefits the Licensor receives from making the Licensed
Material available under these terms and conditions.

Section 1 Definitions.

	Rights that is derived from or based upon the Licensed Material and
	in which the Licensed Material is translated, altered, arranged,

 c. Copyright and Similar Rights means copyright and/or similar
	rights closely related to copyright including, without limitation,
	performance, broadcast, sound recording, and Sui Generis Database
	Rights, without regard to how the rights are labeled or
	categorized. For purposes of this Public License, the rights
	specified in Section 2(b)(1)-(2) are not Copyright and Similar
	Rights.

 d. Effective Technological Measures means those measures that,
	in the absence of proper authority, may not be circumvented under
	laws fulfilling obligations under Article 11 of the WIPO Copyright
	Treaty adopted on December 20, 1996, and/or similar international
	agreements.

 e. Exceptions and Limitations means fair use, fair dealing, and/or
	any other exception or limitation to Copyright and Similar Rights

 f. Licensed Material means the artistic or literary work, database,
	or other material to which the Licensor applied this Public License.

 g. Licensed Rights means the rights granted to You subject to the terms

	public may access the material from a place and at a time
	individually chosen by them.

 j. Sui Generis Database Rights means rights other than copyright
	resulting from Directive 96/9/EC of the European Parliament and
	of the Council of 11 March 1996 on the legal protection of
	databases, as amended and/or succeeded, as well as other
	essentially equivalent rights anywhere in the world.

 k. You means the individual or entity exercising the Licensed
	Rights under this Public License. Your has a corresponding
	meaning.

Section 2 Scope.

 a. License grant.

        1. Subject to the terms and conditions of this Public License,
		the Licensor hereby grants You a worldwide, royalty-free,
		non-sublicensable, non-exclusive, irrevocable license to
		exercise the Licensed Rights in the Licensed Material to:

            A. reproduce and Share the Licensed Material, in whole
			or in part; and

            B. produce, reproduce, and Share Adapted Material.

        2. Exceptions and Limitations. For the avoidance of doubt,
		where Exceptions and Limitations apply to Your use, this
		Public License does not apply, and You do not need to
		comply with its terms and conditions.

        3. Term. The term of this Public License is specified in
		Section 6(a).

        4. Media and formats; technical modifications allowed.
		The Licensor authorizes You to exercise the Licensed
		Rights in all media and formats whether now known or
		hereafter created, and to make technical modifications
		necessary to do so. The Licensor waives and/or agrees
		not to assert any right or authority to forbid You from
		making technical modifications necessary to exercise the
		Licensed Rights, including technical modifications necessary
		to circumvent Effective Technological Measures. For
		purposes of this Public License, simply making
		modifications authorized by this Section 2(a)(4)
		never produces Adapted Material.

        5. Downstream recipients.

            A. Offer from the Licensor ? Licensed Material.
			Every recipient of the Licensed Material
			automatically receives an offer from the
			Licensor to exercise the Licensed Rights
			under the terms and conditions of this Public License.

            B. No downstream restrictions. You may not offer or
			impose any additional or different terms or conditions
			on, or apply any Effective Technological Measures to,
			the Licensed Material if doing so restricts exercise
			of the Licensed Rights by any recipient of the Licensed
			Material.

        6. No endorsement. Nothing in this Public License constitutes
		or may be construed as permission to assert or imply that You
		are, or that Your use of the Licensed Material is, connected
		with, or sponsored, endorsed, or granted official status by,
		the Licensor or others designated to receive attribution as
		provided in Section 3(a)(1)(A)(i).

 b. Other rights.

        1. Moral rights, such as the right of integrity, are not
		licensed under this Public License, nor are publicity,
		privacy, and/or other similar personality rights; however,
		to the extent possible, the Licensor waives and/or agrees
		not to assert any such rights held by the Licensor to the
		limited extent necessary to allow You to exercise the
		Licensed Rights, but not otherwise.

        2. Patent and trademark rights are not licensed under
		this Public License.

        3. To the extent possible, the Licensor waives any right
		to collect royalties from You for the exercise of the
		Licensed Rights, whether directly or through a collecting
		society under any voluntary or waivable statutory or
		compulsory licensing scheme. In all other cases the
		Licensor expressly reserves any right to collect such
		royalties.

Section 3 License Conditions.

Your exercise of the Licensed Rights is expressly made subject to
the following conditions.

 a. Attribution.

        1. If You Share the Licensed Material (including in
		modified form), You must:

            A. retain the following if it is supplied by the
			Licensor with the Licensed Material:
                i. identification of the creator(s) of the Licensed
				Material and any others designated to receive
				attribution, in any reasonable manner requested
				by the Licensor (including by pseudonym if designated);

                ii. a copyright notice;

                iii. a notice that refers to this Public License;

                iv. a notice that refers to the disclaimer of
				warranties;

                v. a URI or hyperlink to the Licensed Material to
				the extent reasonably practicable;

            B. indicate if You modified the Licensed Material and
			retain an indication of any previous modifications; and

            C. indicate the Licensed Material is licensed under
			this Public License, and include the text of, or the
			URI or hyperlink to, this Public License.

        2. You may satisfy the conditions in Section 3(a)(1) in
		any reasonable manner based on the medium, means, and
		context in which You Share the Licensed Material. For
		example, it may be reasonable to satisfy the conditions
		by providing a URI or hyperlink to a resource that
		includes the required information.

        3. If requested by the Licensor, You must remove any
		of the information required by Section 3(a)(1)(A) to the
		extent reasonably practicable.

        4. If You Share Adapted Material You produce, the Adapter's
		License You apply must not prevent recipients of the
		Adapted Material from complying with this Public License.

Section 4 Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

 a. for the avoidance of doubt, Section 2(a)(1) grants You the right
	to extract, reuse, reproduce, and Share all or a substantial
	portion of the contents of the database;

 b. if You include all or a substantial portion of the database
    contents in a database in which You have Sui Generis Database
	Rights, then the database in which You have Sui Generis Database
	Rights (but not its individual contents) is Adapted Material; and

 c. You must comply with the conditions in Section 3(a) if You Share
    all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.

Section 5 Disclaimer of Warranties and Limitation of Liability.

 a. Unless otherwise separately undertaken by the Licensor, to the
	extent possible, the Licensor offers the Licensed Material
	as-is and as-available, and makes no representations or
	warranties of any kind concerning the Licensed Material,
	whether express, implied, statutory, or other. This includes,
	without limitation, warranties of title, merchantability,
	fitness for a particular purpose, non-infringement, absence of
	latent or other defects, accuracy, or the presence or absence
	of errors, whether or not known or discoverable. Where
	disclaimers of warranties are not allowed in full or in part,
	this disclaimer may not apply to You.

 b. To the extent possible, in no event will the Licensor be liable
	to You on any legal theory (including, without limitation,
	negligence) or otherwise for any direct, special, indirect,
	incidental, consequential, punitive, exemplary, or other losses,
	costs, expenses, or damages arising out of this Public License
	or use of the Licensed Material, even if the Licensor has been
	advised of the possibility of such losses, costs, expenses, or
	damages. Where a limitation of liability is not allowed in full
	or in part, this limitation may not apply to You.

 c. The disclaimer of warranties and limitation of liability provided
	above shall be interpreted in a manner that, to the extent
	possible, most closely approximates an absolute disclaimer and
	waiver of all liability.

Section 6 Term and Termination.

 a. This Public License applies for the term of the Copyright and
	Similar Rights licensed here. However, if You fail to comply with
	this Public License, then Your rights under this Public License
	terminate automatically.

 b. Where Your right to use the Licensed Material has terminated
	under Section 6(a), it reinstates:

        1. automatically as of the date the violation is cured, provided
		it is cured within 30 days of Your discovery of the violation; or

        2. upon express reinstatement by the Licensor.

    For the avoidance of doubt, this Section 6(b) does not affect any right
	the Licensor may have to seek remedies for Your violations of this
	Public License.

 c. For the avoidance of doubt, the Licensor may also offer the Licensed
	Material under separate terms or conditions or stop distributing the
	Licensed Material at any time; however, doing so will not terminate
	this Public License.

 d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 Other Terms and Conditions.

 a. The Licensor shall not be bound by any additional or different terms
	or conditions communicated by You unless expressly agreed.

 b. Any arrangements, understandings, or agreements regarding the Licensed
	Material not stated herein are separate from and independent of the
	terms and conditions of this Public License.

Section 8 Interpretation.

 a. For the avoidance of doubt, this Public License does not, and shall not
	be interpreted to, reduce, limit, restrict, or impose conditions on any
	use of the Licensed Material that could lawfully be made without
	permission under this Public License.

 b. To the extent possible, if any provision of this Public License is
	deemed unenforceable, it shall be automatically reformed to the
	minimum extent necessary to make it enforceable. If the provision
	cannot be reformed, it shall be severed from this Public License
	without affecting the enforceability of the remaining terms and
	conditions.

 c. No term or condition of this Public License will be waived and no
	failure to comply consented to unless expressly agreed to by the
	Licensor.

 d. Nothing in this Public License constitutes or may be interpreted as
	a limitation upon, or waiver of, any privileges and immunities that
	apply to the Licensor or You, including from the legal processes of
	any jurisdiction or authority.
