The 32 | following considerations are for informational purposes only, are not 33 | exhaustive, and do not form part of our licenses. 34 | 35 | Considerations for licensors: Our public licenses are 36 | intended for use by those authorized to give the public 37 | permission to use material in ways otherwise restricted by 38 | copyright and certain other rights. Our licenses are 39 | irrevocable. Licensors should read and understand the terms 40 | and conditions of the license they choose before applying it. 41 | Licensors should also secure all rights necessary before 42 | applying our licenses so that the public can reuse the 43 | material as expected. Licensors should clearly mark any 44 | material not subject to the license. This includes other CC- 45 | licensed material, or material used under an exception or 46 | limitation to copyright.

If 52 | the licensor's permission is not necessary for any reason--for 53 | example, because of any applicable exception or limitation to 54 | copyright--then that use is not regulated by the license. Our 55 | licenses grant only permissions under copyright and certain 56 | other rights that a licensor has authority to grant. Use of 57 | the licensed material may still be restricted for other 58 | reasons, including because others have copyright or other 59 | rights in the material. A licensor may make special requests, 60 | such as asking that all changes be marked or described. 61 | Although not required by our licenses, you are encouraged to 62 | respect those requests where reasonable.

To the 73 | extent this Public License may be interpreted as a contract, You are 74 | granted the Licensed Rights in consideration of Your acceptance of 75 | these terms and conditions, and the Licensor grants You such rights in 76 | consideration of benefits the Licensor receives from making the 77 | Licensed Material available under these terms and conditions. 78 | 79 | 80 | Section 1 -- Definitions. 81 | 82 | a. Adapted Material means material subject to Copyright and Similar 83 | Rights that is derived from or based upon the Licensed Material 84 | and in which the Licensed Material is translated, altered, 85 | arranged, transformed, or otherwise modified in a manner requiring 86 | permission under the Copyright and Similar Rights held by the 87 | Licensor. For purposes of this Public License, where the Licensed 88 | Material is a musical work, performance, or sound recording, 89 | Adapted Material is always produced where the Licensed Material is 90 | synched in timed relation with a moving image. 91 | 92 | b.

For purposes of this Public License, the rights 101 | specified in Section 2(b)(1)-(2) are not Copyright and Similar 102 | Rights. 103 | 104 | d. Effective Technological Measures means those measures that, in the 105 | absence of proper authority, may not be circumvented under laws 106 | fulfilling obligations under Article 11 of the WIPO Copyright 107 | Treaty adopted on December 20, 1996, and/or similar international 108 | agreements. 109 | 110 | e. Exceptions and Limitations means fair use, fair dealing, and/or 111 | any other exception or limitation to Copyright and Similar Rights 112 | that applies to Your use of the Licensed Material. 113 | 114 | f. Licensed Material means the artistic or literary work, database, 115 | or other material to which the Licensor applied this Public 116 | License. 117 | 118 | g.

Licensor means the individual(s) or entity(ies) granting rights 124 | under this Public License. 125 | 126 | i. Share means to provide material to the public by any means or 127 | process that requires permission under the Licensed Rights, such 128 | as reproduction, public display, public performance, distribution, 129 | dissemination, communication, or importation, and to make material 130 | available to the public including in ways that members of the 131 | public may access the material from a place and at a time 132 | individually chosen by them. 133 | 134 | j. Sui Generis Database Rights means rights other than copyright 135 | resulting from Directive 96/9/EC of the European Parliament and of 136 | the Council of 11 March 1996 on the legal protection of databases, 137 | as amended and/or succeeded, as well as other essentially 138 | equivalent rights anywhere in the world. 139 | 140 | k.

Subject to the terms and conditions of this Public License, 149 | the Licensor hereby grants You a worldwide, royalty-free, 150 | non-sublicensable, non-exclusive, irrevocable license to 151 | exercise the Licensed Rights in the Licensed Material to: 152 | 153 | a. reproduce and Share the Licensed Material, in whole or 154 | in part; and 155 | 156 | b. produce, reproduce, and Share Adapted Material. 157 | 158 | 2. Exceptions and Limitations. For the avoidance of doubt, where 159 | Exceptions and Limitations apply to Your use, this Public 160 | License does not apply, and You do not need to comply with 161 | its terms and conditions. 162 | 163 | 3. Term. The term of this Public License is specified in Section 164 | 6(a). 165 | 166 | 4. Media and formats; technical modifications allowed. The 167 | Licensor authorizes You to exercise the Licensed Rights in 168 | all media and formats whether now known or hereafter created, 169 | and to make technical modifications necessary to do so. The 170 | Licensor waives and/or agrees not to assert any right or 171 | authority to forbid You from making technical modifications 172 | necessary to exercise the Licensed Rights, including 173 | technical modifications necessary to circumvent Effective 174 | Technological Measures. For purposes of this Public License, 175 | simply making modifications authorized by this Section 2(a) 176 | (4) never produces Adapted Material. 177 | 178 | 5. Downstream recipients. 179 | 180 | a. Offer from the Licensor -- Licensed Material. Every 181 | recipient of the Licensed Material automatically 182 | receives an offer from the Licensor to exercise the 183 | Licensed Rights under the terms and conditions of this 184 | Public License. 185 | 186 | b. No downstream restrictions. You may not offer or impose 187 | any additional or different terms or conditions on, or 188 | apply any Effective Technological Measures to, the 189 | Licensed Material if doing so restricts exercise of the 190 | Licensed Rights by any recipient of the Licensed 191 | Material. 192 | 193 | 6. No endorsement. Nothing in this Public License constitutes or 194 | may be construed as permission to assert or imply that You 195 | are, or that Your use of the Licensed Material is, connected 196 | with, or sponsored, endorsed, or granted official status by, 197 | the Licensor or others designated to receive attribution as 198 | provided in Section 3(a)(1)(A)(i). 199 | 200 | b. Other rights. 201 | 202 | 1. Moral rights, such as the right of integrity, are not 203 | licensed under this Public License, nor are publicity, 204 | privacy, and/or other similar personality rights; however, to 205 | the extent possible, the Licensor waives and/or agrees not to 206 | assert any such rights held by the Licensor to the limited 207 | extent necessary to allow You to exercise the Licensed 208 | Rights, but not otherwise. 209 | 210 | 2. Patent and trademark rights are not licensed under this 211 | Public License. 212 | 213 | 3. To the extent possible, the Licensor waives any right to 214 | collect royalties from You for the exercise of the Licensed 215 | Rights, whether directly or through a collecting society 216 | under any voluntary or waivable statutory or compulsory 217 | licensing scheme. In all other cases the Licensor expressly 218 | reserves any right to collect such royalties. 219 | 220 | 221 | Section 3 -- License Conditions. 222 | 223 | Your exercise of the Licensed Rights is expressly made subject to the 224 | following conditions. 225 | 226 | a. Attribution. 227 | 228 | 1. If You Share the Licensed Material (including in modified 229 | form), You must: 230 | 231 | a. retain the following if it is supplied by the Licensor 232 | with the Licensed Material: 233 | 234 | i. identification of the creator(s) of the Licensed 235 | Material and any others designated to receive 236 | attribution, in any reasonable manner requested by 237 | the Licensor (including by pseudonym if 238 | designated); 239 | 240 | ii. a copyright notice; 241 | 242 | iii. a notice that refers to this Public License; 243 | 244 | iv. a notice that refers to the disclaimer of 245 | warranties; 246 | 247 | v. a URI or hyperlink to the Licensed Material to the 248 | extent reasonably practicable; 249 | 250 | b. indicate if You modified the Licensed Material and 251 | retain an indication of any previous modifications; and 252 | 253 | c. indicate the Licensed Material is licensed under this 254 | Public License, and include the text of, or the URI or 255 | hyperlink to, this Public License. 256 | 257 | 2. You may satisfy the conditions in Section 3(a)(1) in any 258 | reasonable manner based on the medium, means, and context in 259 | which You Share the Licensed Material. For example, it may be 260 | reasonable to satisfy the conditions by providing a URI or 261 | hyperlink to a resource that includes the required 262 | information. 263 | 264 | 3. If requested by the Licensor, You must remove any of the 265 | information required by Section 3(a)(1)(A) to the extent 266 | reasonably practicable. 267 | 268 | 4. If You Share Adapted Material You produce, the Adapter's 269 | License You apply must not prevent recipients of the Adapted 270 | Material from complying with this Public License. 271 | 272 | 273 | Section 4 -- Sui Generis Database Rights. 274 | 275 | Where the Licensed Rights include Sui Generis Database Rights that 276 | apply to Your use of the Licensed Material: 277 | 278 | a. for the avoidance of doubt, Section 2(a)(1) grants You the right 279 | to extract, reuse, reproduce, and Share all or a substantial 280 | portion of the contents of the database; 281 | 282 | b. if You include all or a substantial portion of the database 283 | contents in a database in which You have Sui Generis Database 284 | Rights, then the database in which You have Sui Generis Database 285 | Rights (but not its individual contents) is Adapted Material; and 286 | 287 | c. You must comply with the conditions in Section 3(a) if You Share 288 | all or a substantial portion of the contents of the database. 289 | 290 | For the avoidance of doubt, this Section 4 supplements and does not 291 | replace Your obligations under this Public License where the Licensed 292 | Rights include other Copyright and Similar Rights. 293 | 294 | 295 | Section 5 -- Disclaimer of Warranties and Limitation of Liability. 296 | 297 | a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE 298 | EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS 299 | AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF 300 | ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, 301 | IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, 302 | WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR 303 | PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, 304 | ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT 305 | KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT 306 | ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU. 307 | 308 | b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE 309 | TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, 310 | NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, 311 | INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, 312 | COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR 313 | USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN 314 | ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR 315 | DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR 316 | IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. 317 | 318 | c. The disclaimer of warranties and limitation of liability provided 319 | above shall be interpreted in a manner that, to the extent 320 | possible, most closely approximates an absolute disclaimer and 321 | waiver of all liability. 322 | 323 | 324 | Section 6 -- Term and Termination. 325 | 326 | a. This Public License applies for the term of the Copyright and 327 | Similar Rights licensed here. However, if You fail to comply with 328 | this Public License, then Your rights under this Public License 329 | terminate automatically. 330 | 331 | b. Where Your right to use the Licensed Material has terminated under 332 | Section 6(a), it reinstates: 333 | 334 | 1. automatically as of the date the violation is cured, provided 335 | it is cured within 30 days of Your discovery of the 336 | violation; or 337 | 338 | 2. upon express reinstatement by the Licensor. 339 | 340 | For the avoidance of doubt, this Section 6(b) does not affect any 341 | right the Licensor may have to seek remedies for Your violations 342 | of this Public License. 343 | 344 | c. For the avoidance of doubt, the Licensor may also offer the 345 | Licensed Material under separate terms or conditions or stop 346 | distributing the Licensed Material at any time; however, doing so 347 | will not terminate this Public License. 348 | 349 | d. Sections 1, 5, 6, 7, and 8 survive termination of this Public 350 | License. 351 | 352 | 353 | Section 7 -- Other Terms and Conditions. 354 | 355 | a. The Licensor shall not be bound by any additional or different 356 | terms or conditions communicated by You unless expressly agreed. 357 | 358 | b. Any arrangements, understandings, or agreements regarding the 359 | Licensed Material not stated herein are separate from and 360 | independent of the terms and conditions of this Public License. 361 | 362 | 363 | Section 8 -- Interpretation. 364 | 365 | a. For the avoidance of doubt, this Public License does not, and 366 | shall not be interpreted to, reduce, limit, restrict, or impose 367 | conditions on any use of the Licensed Material that could lawfully 368 | be made without permission under this Public License. 369 | 370 | b. To the extent possible, if any provision of this Public License is 371 | deemed unenforceable, it shall be automatically reformed to the 372 | minimum extent necessary to make it enforceable. If the provision 373 | cannot be reformed, it shall be severed from this Public License 374 | without affecting the enforceability of the remaining terms and 375 | conditions. 376 | 377 | c. No term or condition of this Public License will be waived and no 378 | failure to comply consented to unless expressly agreed to by the 379 | Licensor. 380 | 381 | d. Nothing in this Public License constitutes or may be interpreted 382 | as a limitation upon, or waiver of, any privileges and immunities 383 | that apply to the Licensor or You, including from the legal 384 | processes of any jurisdiction or authority. 385 | 386 | 387 | ======================================================================= 388 | 389 | Creative Commons is not a party to its public 390 | licenses.
