No downstream restrictions. You may not offer or impose 204 | any additional or different terms or conditions on, or 205 | apply any Effective Technological Measures to, the 206 | Licensed Material if doing so restricts exercise of the 207 | Licensed Rights by any recipient of the Licensed 208 | Material. 209 | 210 | 6. No endorsement. Nothing in this Public License constitutes or 211 | may be construed as permission to assert or imply that You 212 | are, or that Your use of the Licensed Material is, connected 213 | with, or sponsored, endorsed, or granted official status by, 214 | the Licensor or others designated to receive attribution as 215 | provided in Section 3(a)(1)(A)(i). 216 | 217 | b. Other rights. 218 | 219 | 1. Moral rights, such as the right of integrity, are not 220 | licensed under this Public License, nor are publicity, 221 | privacy, and/or other similar personality rights; however, to 222 | the extent possible, the Licensor waives and/or agrees not to 223 | assert any such rights held by the Licensor to the limited 224 | extent necessary to allow You to exercise the Licensed 225 | Rights, but not otherwise. 226 | 227 | 2. Patent and trademark rights are not licensed under this 228 | Public License. 229 | 230 | 3. To the extent possible, the Licensor waives any right to 231 | collect royalties from You for the exercise of the Licensed 232 | Rights, whether directly or through a collecting society 233 | under any voluntary or waivable statutory or compulsory 234 | licensing scheme.

Attribution. 246 | 247 | 1. If You Share the Licensed Material (including in modified 248 | form), You must: 249 | 250 | a. retain the following if it is supplied by the Licensor 251 | with the Licensed Material: 252 | 253 | i. identification of the creator(s) of the Licensed 254 | Material and any others designated to receive 255 | attribution, in any reasonable manner requested by 256 | the Licensor (including by pseudonym if 257 | designated); 258 | 259 | ii. a copyright notice; 260 | 261 | iii. a notice that refers to this Public License; 262 | 263 | iv. a notice that refers to the disclaimer of 264 | warranties; 265 | 266 | v. a URI or hyperlink to the Licensed Material to the 267 | extent reasonably practicable; 268 | 269 | b. indicate if You modified the Licensed Material and 270 | retain an indication of any previous modifications; and 271 | 272 | c. indicate the Licensed Material is licensed under this 273 | Public License, and include the text of, or the URI or 274 | hyperlink to, this Public License. 275 | 276 | 2. You may satisfy the conditions in Section 3(a)(1) in any 277 | reasonable manner based on the medium, means, and context in 278 | which You Share the Licensed Material.

If requested by the Licensor, You must remove any of the 283 | information required by Section 3(a)(1)(A) to the extent 284 | reasonably practicable. 285 | 286 | b. ShareAlike. 287 | 288 | In addition to the conditions in Section 3(a), if You Share 289 | Adapted Material You produce, the following conditions also apply. 290 | 291 | 1. The Adapter's License You apply must be a Creative Commons 292 | license with the same License Elements, this version or 293 | later, or a BY-NC-SA Compatible License. 294 | 295 | 2. You must include the text of, or the URI or hyperlink to, the 296 | Adapter's License You apply. You may satisfy this condition 297 | in any reasonable manner based on the medium, means, and 298 | context in which You Share Adapted Material. 299 | 300 | 3. You may not offer or impose any additional or different terms 301 | or conditions on, or apply any Effective Technological 302 | Measures to, Adapted Material that restrict exercise of the 303 | rights granted under the Adapter's License You apply. 304 | 305 | 306 | Section 4 -- Sui Generis Database Rights. 307 | 308 | Where the Licensed Rights include Sui Generis Database Rights that 309 | apply to Your use of the Licensed Material: 310 | 311 | a. for the avoidance of doubt, Section 2(a)(1) grants You the right 312 | to extract, reuse, reproduce, and Share all or a substantial 313 | portion of the contents of the database for NonCommercial purposes 314 | only; 315 | 316 | b. if You include all or a substantial portion of the database 317 | contents in a database in which You have Sui Generis Database 318 | Rights, then the database in which You have Sui Generis Database 319 | Rights (but not its individual contents) is Adapted Material, 320 | including for purposes of Section 3(b); and 321 | 322 | c. You must comply with the conditions in Section 3(a) if You Share 323 | all or a substantial portion of the contents of the database. 324 | 325 | For the avoidance of doubt, this Section 4 supplements and does not 326 | replace Your obligations under this Public License where the Licensed 327 | Rights include other Copyright and Similar Rights. 328 | 329 | 330 | Section 5 -- Disclaimer of Warranties and Limitation of Liability. 331 | 332 | a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE 333 | EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS 334 | AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF 335 | ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, 336 | IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, 337 | WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR 338 | PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, 339 | ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT 340 | KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT 341 | ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU. 342 | 343 | b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE 344 | TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, 345 | NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, 346 | INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, 347 | COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR 348 | USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN 349 | ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR 350 | DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR 351 | IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. 352 | 353 | c. The disclaimer of warranties and limitation of liability provided 354 | above shall be interpreted in a manner that, to the extent 355 | possible, most closely approximates an absolute disclaimer and 356 | waiver of all liability. 357 | 358 | 359 | Section 6 -- Term and Termination. 360 | 361 | a. This Public License applies for the term of the Copyright and 362 | Similar Rights licensed here.

Where Your right to use the Licensed Material has terminated under 367 | Section 6(a), it reinstates: 368 | 369 | 1. automatically as of the date the violation is cured, provided 370 | it is cured within 30 days of Your discovery of the 371 | violation; or 372 | 373 | 2. upon express reinstatement by the Licensor. 374 | 375 | For the avoidance of doubt, this Section 6(b) does not affect any 376 | right the Licensor may have to seek remedies for Your violations 377 | of this Public License. 378 | 379 | c. For the avoidance of doubt, the Licensor may also offer the 380 | Licensed Material under separate terms or conditions or stop 381 | distributing the Licensed Material at any time; however, doing so 382 | will not terminate this Public License. 383 | 384 | d. Sections 1, 5, 6, 7, and 8 survive termination of this Public 385 | License. 386 | 387 | 388 | Section 7 -- Other Terms and Conditions. 389 | 390 | a.

To the extent possible, if any provision of this Public License is 406 | deemed unenforceable, it shall be automatically reformed to the 407 | minimum extent necessary to make it enforceable. If the provision 408 | cannot be reformed, it shall be severed from this Public License 409 | without affecting the enforceability of the remaining terms and 410 | conditions. 411 | 412 | c. No term or condition of this Public License will be waived and no 413 | failure to comply consented to unless expressly agreed to by the 414 | Licensor. 415 | 416 | d. Nothing in this Public License constitutes or may be interpreted 417 | as a limitation upon, or waiver of, any privileges and immunities 418 | that apply to the Licensor or You, including from the legal 419 | processes of any jurisdiction or authority. 420 | 421 | ======================================================================= 422 | 423 | Creative Commons is not a party to its public 424 | licenses.
