Exceptions and Limitations. For the avoidance of doubt, where 156 | Exceptions and Limitations apply to Your use, this Public 157 | License does not apply, and You do not need to comply with 158 | its terms and conditions. 159 | 160 | 3. Term. The term of this Public License is specified in Section 161 | 6(a). 162 | 163 | 4. Media and formats; technical modifications allowed.

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