The 21 | following considerations are for informational purposes only, are not 22 | exhaustive, and do not form part of our licenses. 23 | 24 | Considerations for licensors: Our public licenses are 25 | intended for use by those authorized to give the public 26 | permission to use material in ways otherwise restricted by 27 | copyright and certain other rights. Our licenses are 28 | irrevocable. Licensors should read and understand the terms 29 | and conditions of the license they choose before applying it. 30 | Licensors should also secure all rights necessary before 31 | applying our licenses so that the public can reuse the 32 | material as expected. Licensors should clearly mark any 33 | material not subject to the license. This includes other CC- 34 | licensed material, or material used under an exception or 35 | limitation to copyright. More considerations for licensors: 36 | wiki.creativecommons.org/Considerations_for_licensors 37 | 38 | Considerations for the public: By using one of our public 39 | licenses, a licensor grants the public permission to use the 40 | licensed material under specified terms and conditions. If 41 | the licensor's permission is not necessary for any reason--for 42 | example, because of any applicable exception or limitation to 43 | copyright--then that use is not regulated by the license. Our 44 | licenses grant only permissions under copyright and certain 45 | other rights that a licensor has authority to grant. Use of 46 | the licensed material may still be restricted for other 47 | reasons, including because others have copyright or other 48 | rights in the material. A licensor may make special requests, 49 | such as asking that all changes be marked or described. 50 | Although not required by our licenses, you are encouraged to 51 | respect those requests where reasonable.

To the extent this Public License may be interpreted as a 64 | contract, You are granted the Licensed Rights in consideration of Your 65 | acceptance of these terms and conditions, and the Licensor grants You 66 | such rights in consideration of benefits the Licensor receives from 67 | making the Licensed Material available under these terms and 68 | conditions. 69 | 70 | 71 | Section 1 -- Definitions. 72 | 73 | a. Adapted Material means material subject to Copyright and Similar 74 | Rights that is derived from or based upon the Licensed Material 75 | and in which the Licensed Material is translated, altered, 76 | arranged, transformed, or otherwise modified in a manner requiring 77 | permission under the Copyright and Similar Rights held by the 78 | Licensor.

Effective Technological Measures means those measures that, in the 100 | absence of proper authority, may not be circumvented under laws 101 | fulfilling obligations under Article 11 of the WIPO Copyright 102 | Treaty adopted on December 20, 1996, and/or similar international 103 | agreements. 104 | 105 | f. Exceptions and Limitations means fair use, fair dealing, and/or 106 | any other exception or limitation to Copyright and Similar Rights 107 | that applies to Your use of the Licensed Material. 108 | 109 | g.

Share means to provide material to the public by any means or 126 | process that requires permission under the Licensed Rights, such 127 | as reproduction, public display, public performance, distribution, 128 | dissemination, communication, or importation, and to make material 129 | available to the public including in ways that members of the 130 | public may access the material from a place and at a time 131 | individually chosen by them. 132 | 133 | l. Sui Generis Database Rights means rights other than copyright 134 | resulting from Directive 96/9/EC of the European Parliament and of 135 | the Council of 11 March 1996 on the legal protection of databases, 136 | as amended and/or succeeded, as well as other essentially 137 | equivalent rights anywhere in the world. 138 | 139 | m. You means the individual or entity exercising the Licensed Rights 140 | under this Public License. Your has a corresponding meaning. 141 | 142 | 143 | Section 2 -- Scope. 144 | 145 | a. License grant. 146 | 147 | 1. Subject to the terms and conditions of this Public License, 148 | the Licensor hereby grants You a worldwide, royalty-free, 149 | non-sublicensable, non-exclusive, irrevocable license to 150 | exercise the Licensed Rights in the Licensed Material to: 151 | 152 | a. reproduce and Share the Licensed Material, in whole or 153 | in part; and 154 | 155 | b. produce, reproduce, and Share Adapted Material. 156 | 157 | 2. Exceptions and Limitations. For the avoidance of doubt, where 158 | Exceptions and Limitations apply to Your use, this Public 159 | License does not apply, and You do not need to comply with 160 | its terms and conditions. 161 | 162 | 3. Term. The term of this Public License is specified in Section 163 | 6(a). 164 | 165 | 4. Media and formats; technical modifications allowed. The 166 | Licensor authorizes You to exercise the Licensed Rights in 167 | all media and formats whether now known or hereafter created, 168 | and to make technical modifications necessary to do so. The 169 | Licensor waives and/or agrees not to assert any right or 170 | authority to forbid You from making technical modifications 171 | necessary to exercise the Licensed Rights, including 172 | technical modifications necessary to circumvent Effective 173 | Technological Measures. For purposes of this Public License, 174 | simply making modifications authorized by this Section 2(a) 175 | (4) never produces Adapted Material. 176 | 177 | 5. Downstream recipients. 178 | 179 | a. Offer from the Licensor -- Licensed Material. Every 180 | recipient of the Licensed Material automatically 181 | receives an offer from the Licensor to exercise the 182 | Licensed Rights under the terms and conditions of this 183 | Public License. 184 | 185 | b. Additional offer from the Licensor -- Adapted Material. 186 | Every recipient of Adapted Material from You 187 | automatically receives an offer from the Licensor to 188 | exercise the Licensed Rights in the Adapted Material 189 | under the conditions of the Adapter's License You apply. 190 | 191 | c. No downstream restrictions. You may not offer or impose 192 | any additional or different terms or conditions on, or 193 | apply any Effective Technological Measures to, the 194 | Licensed Material if doing so restricts exercise of the 195 | Licensed Rights by any recipient of the Licensed 196 | Material. 197 | 198 | 6. No endorsement. Nothing in this Public License constitutes or 199 | may be construed as permission to assert or imply that You 200 | are, or that Your use of the Licensed Material is, connected 201 | with, or sponsored, endorsed, or granted official status by, 202 | the Licensor or others designated to receive attribution as 203 | provided in Section 3(a)(1)(A)(i). 204 | 205 | b. Other rights. 206 | 207 | 1. Moral rights, such as the right of integrity, are not 208 | licensed under this Public License, nor are publicity, 209 | privacy, and/or other similar personality rights; however, to 210 | the extent possible, the Licensor waives and/or agrees not to 211 | assert any such rights held by the Licensor to the limited 212 | extent necessary to allow You to exercise the Licensed 213 | Rights, but not otherwise. 214 | 215 | 2. Patent and trademark rights are not licensed under this 216 | Public License. 217 | 218 | 3. To the extent possible, the Licensor waives any right to 219 | collect royalties from You for the exercise of the Licensed 220 | Rights, whether directly or through a collecting society 221 | under any voluntary or waivable statutory or compulsory 222 | licensing scheme. In all other cases the Licensor expressly 223 | reserves any right to collect such royalties. 224 | 225 | 226 | Section 3 -- License Conditions. 227 | 228 | Your exercise of the Licensed Rights is expressly made subject to the 229 | following conditions. 230 | 231 | a. Attribution. 232 | 233 | 1. If You Share the Licensed Material (including in modified 234 | form), You must: 235 | 236 | a. retain the following if it is supplied by the Licensor 237 | with the Licensed Material: 238 | 239 | i. identification of the creator(s) of the Licensed 240 | Material and any others designated to receive 241 | attribution, in any reasonable manner requested by 242 | the Licensor (including by pseudonym if 243 | designated); 244 | 245 | ii. a copyright notice; 246 | 247 | iii. a notice that refers to this Public License; 248 | 249 | iv. a notice that refers to the disclaimer of 250 | warranties; 251 | 252 | v. a URI or hyperlink to the Licensed Material to the 253 | extent reasonably practicable; 254 | 255 | b. indicate if You modified the Licensed Material and 256 | retain an indication of any previous modifications; and 257 | 258 | c. indicate the Licensed Material is licensed under this 259 | Public License, and include the text of, or the URI or 260 | hyperlink to, this Public License. 261 | 262 | 2. You may satisfy the conditions in Section 3(a)(1) in any 263 | reasonable manner based on the medium, means, and context in 264 | which You Share the Licensed Material. For example, it may be 265 | reasonable to satisfy the conditions by providing a URI or 266 | hyperlink to a resource that includes the required 267 | information. 268 | 269 | 3. If requested by the Licensor, You must remove any of the 270 | information required by Section 3(a)(1)(A) to the extent 271 | reasonably practicable. 272 | 273 | b. ShareAlike. 274 | 275 | In addition to the conditions in Section 3(a), if You Share 276 | Adapted Material You produce, the following conditions also apply. 277 | 278 | 1. The Adapter's License You apply must be a Creative Commons 279 | license with the same License Elements, this version or 280 | later, or a BY-SA Compatible License. 281 | 282 | 2. You must include the text of, or the URI or hyperlink to, the 283 | Adapter's License You apply. You may satisfy this condition 284 | in any reasonable manner based on the medium, means, and 285 | context in which You Share Adapted Material. 286 | 287 | 3. You may not offer or impose any additional or different terms 288 | or conditions on, or apply any Effective Technological 289 | Measures to, Adapted Material that restrict exercise of the 290 | rights granted under the Adapter's License You apply. 291 | 292 | 293 | Section 4 -- Sui Generis Database Rights. 294 | 295 | Where the Licensed Rights include Sui Generis Database Rights that 296 | apply to Your use of the Licensed Material: 297 | 298 | a. for the avoidance of doubt, Section 2(a)(1) grants You the right 299 | to extract, reuse, reproduce, and Share all or a substantial 300 | portion of the contents of the database; 301 | 302 | b. if You include all or a substantial portion of the database 303 | contents in a database in which You have Sui Generis Database 304 | Rights, then the database in which You have Sui Generis Database 305 | Rights (but not its individual contents) is Adapted Material, 306 | including for purposes of Section 3(b); and 307 | 308 | c. You must comply with the conditions in Section 3(a) if You Share 309 | all or a substantial portion of the contents of the database. 310 | 311 | For the avoidance of doubt, this Section 4 supplements and does not 312 | replace Your obligations under this Public License where the Licensed 313 | Rights include other Copyright and Similar Rights. 314 | 315 | 316 | Section 5 -- Disclaimer of Warranties and Limitation of Liability. 317 | 318 | a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE 319 | EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS 320 | AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF 321 | ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, 322 | IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, 323 | WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR 324 | PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, 325 | ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT 326 | KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT 327 | ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU. 328 | 329 | b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE 330 | TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, 331 | NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, 332 | INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, 333 | COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR 334 | USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN 335 | ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR 336 | DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR 337 | IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. 338 | 339 | c. The disclaimer of warranties and limitation of liability provided 340 | above shall be interpreted in a manner that, to the extent 341 | possible, most closely approximates an absolute disclaimer and 342 | waiver of all liability. 343 | 344 | 345 | Section 6 -- Term and Termination. 346 | 347 | a. This Public License applies for the term of the Copyright and 348 | Similar Rights licensed here. However, if You fail to comply with 349 | this Public License, then Your rights under this Public License 350 | terminate automatically. 351 | 352 | b. Where Your right to use the Licensed Material has terminated under 353 | Section 6(a), it reinstates: 354 | 355 | 1. automatically as of the date the violation is cured, provided 356 | it is cured within 30 days of Your discovery of the 357 | violation; or 358 | 359 | 2. upon express reinstatement by the Licensor. 360 | 361 | For the avoidance of doubt, this Section 6(b) does not affect any 362 | right the Licensor may have to seek remedies for Your violations 363 | of this Public License. 364 | 365 | c. For the avoidance of doubt, the Licensor may also offer the 366 | Licensed Material under separate terms or conditions or stop 367 | distributing the Licensed Material at any time; however, doing so 368 | will not terminate this Public License. 369 | 370 | d. Sections 1, 5, 6, 7, and 8 survive termination of this Public 371 | License. 372 | 373 | 374 | Section 7 -- Other Terms and Conditions. 375 | 376 | a. The Licensor shall not be bound by any additional or different 377 | terms or conditions communicated by You unless expressly agreed. 378 | 379 | b. Any arrangements, understandings, or agreements regarding the 380 | Licensed Material not stated herein are separate from and 381 | independent of the terms and conditions of this Public License. 382 | 383 | 384 | Section 8 -- Interpretation. 385 | 386 | a. For the avoidance of doubt, this Public License does not, and 387 | shall not be interpreted to, reduce, limit, restrict, or impose 388 | conditions on any use of the Licensed Material that could lawfully 389 | be made without permission under this Public License. 390 | 391 | b. To the extent possible, if any provision of this Public License is 392 | deemed unenforceable, it shall be automatically reformed to the 393 | minimum extent necessary to make it enforceable. If the provision 394 | cannot be reformed, it shall be severed from this Public License 395 | without affecting the enforceability of the remaining terms and 396 | conditions. 397 | 398 | c. No term or condition of this Public License will be waived and no 399 | failure to comply consented to unless expressly agreed to by the 400 | Licensor. 401 | 402 | d. Nothing in this Public License constitutes or may be interpreted 403 | as a limitation upon, or waiver of, any privileges and immunities 404 | that apply to the Licensor or You, including from the legal 405 | processes of any jurisdiction or authority. 406 | 407 | 408 | ======================================================================= 409 | 410 | Creative Commons is not a party to its public 411 | licenses.
