By exercising the Licensed Rights (defined below), You accept and agree to be 
bound by the terms and conditions of this Creative Commons 
Attribution-ShareAlike 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

    that is derived from or based upon the Licensed Material and in which the 
    Licensed Material is translated, altered, arranged, transformed, or 
    otherwise modified in a manner requiring permission under the Copyright 
    and Similar Rights held by the Licensor. For purposes of this Public 
    License, where the Licensed Material is a musical work, performance, or

    Public License, the rights specified in Section 2(b)(1)-(2) are not 
    Copyright and Similar Rights.

    e. 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

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

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

    that requires permission under the Licensed Rights, such as reproduction,

    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 s
    ucceeded, as well as other essentially equivalent rights anywhere in the 
    world.

    m. 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. Additional offer from the Licensor – Adapted Material. Every 
			recipient of Adapted Material from You automatically receives an 
			offer from the Licensor to exercise the Licensed Rights in the 
			Adapted Material under the conditions of the Adapter’s License 
			You apply.

			C. 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;

			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.

	b. ShareAlike.

	In addition to the conditions in Section 3(a), if You Share Adapted 
	Material You produce, the following conditions also apply.

		1. The Adapter’s License You apply must be a Creative Commons license 
		with the same License Elements, this version or later, or a BY-SA 
		Compatible License.

		2. You must include the text of, or the URI or hyperlink to, the 
		Adapter's License You apply. You may satisfy this condition in any 
		reasonable manner based on the medium, means, and context in which 
		You Share Adapted Material.

		3. You may not offer or impose any additional or different terms or 
		conditions on, or apply any Effective Technological Measures to, 
		Adapted Material that restrict exercise of the rights granted under 
		the Adapter's License You apply.

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, including for purposes of 
	Section 3(b); 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.
