Prohibitions

This license states no prohibitions.

License-wide duties

This license states no duties that apply to the work as a whole.

What applies by default

The statements above are the library's reading of this license: each is marked with the sentence it rests on, or as a library convention where the text is not explicit. The statements below are the ones the DALICC reasoner supplies for acts the license says nothing about, from the default rules of the dependency graph it reasons with. Each one names the legal source it rests on. None of it is in the record.

  • Promote by default rule (adopted) Using the name or trademarks of the licensor or of contributors to endorse or promote a product.

    This license says nothing about Promote, and the graph applies this reading in all jurisdictions it covers: it is not permitted unless the license permits it.

    A licence that says nothing about endorsement is read as not allowing it: the licence gives the licensee no right to use the licensor's name or marks in a way that states or implies that the licensor endorses the licensee or its product, while stating truthfully that a work is based on or uses the licensed work is a different act that this rule does not decide. A copyright licence grants rights in the work, and the right to use a name or a trademark is a separate right under trademark law and the protection of names, which a silent copyright licence does not pass on. Combining a licence that is silent about endorsement with one that permits it shows a conflict marked as coming from this rule.

    Basis Trademark and name rights are separate from copyright: Regulation (EU) 2017/1001 article 9 lets the proprietor of an EU trade mark prevent all third parties not having his consent from using the sign in the course of trade, and Directive (EU) 2015/2436 article 10, 15 U.S.C. 1114 and 1125(a), section 12 BGB and section 43 ABGB protect marks and names in the same way. The library's evidence is Creative Commons 4.0 section 2(b)(2): Patent and trademark rights are not licensed under this Public License. A copyright licence that is silent grants no right to use the licensor's name or marks to suggest endorsement (Worldwide)

Further terms

These are the things the license says about itself beyond the acts it permits, forbids and requires: when it ends, how long there is to put a breach right, which law governs it, and so on. A term that comes from the DALICC vocabulary links to its definition.

Patent license ends if you sue
Yes. Not a ban on suing: a patent claim over the work ends the patent license, or the whole license, as the text provides.
Or later version option
Yes
Sublicense survival
Yes
Terminates on breach
Yes

Clauses

Warranty disclaimer

6.1 EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE DATA (INCLUDING ENHANCED DATA) IS PROVIDED ON AN “AS IS” BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

Limitation of liability

6.2 NEITHER YOU NOR ANY DATA PROVIDERS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE DATA OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Additional clauses

2.1 Subject to the conditions set forth in Section 3 of this Agreement, Data Provider(s) hereby grant(s) to You a worldwide, non-exclusive, irrevocable (except as provided in Section 5) right to: (a) Use Data; and (b) Publish Data. 2.2 To the extent that the Data or the coordination, selection or arrangement of Data is protected or protectable under copyright, Sui Generis Database Rights, or other law, Data Provider(s) further agree(s) that such Data or coordination, selection or arrangement is hereby licensed to You and to anyone else who Receives Data under this Agreement for Use and Publication, subject to the conditions set forth in Section 3 of this Agreement. 2.3 Except for these rights and licenses expressly granted, no other intellectual property rights are granted or should be implied. (a) You may do so under a license of Your choice provided that You give anyone who Receives the Data from You the text of this Agreement, the name of this Agreement and/or a hyperlink or other method reasonably likely to provide a copy of the text of this Agreement; and (b) You must cause any Data files containing Enhanced Data to carry prominent notices that You have changed those files; and (c) If You Publish Data You Receive, You must preserve all credit or attribution to the Data Provider(s). Such retained credit or attribution includes any of the following to the extent they exist in Data as You have Received it: legal notices or metadata; identification of the Data Provider(s); or hyperlinks to Data to the extent it is practical to do so. 3.2 You may provide additional or different license terms and conditions for use, reproduction, or distribution of that Enhanced Data, or for any combination of Data and Enhanced Data as a whole, provided that Your Use and Publication of that combined Data otherwise complies with the conditions stated in this License. 3.3 You and each Data Provider agree that Enhanced Data shall not be considered a work of joint authorship by virtue of its relationship to Data licensed under this Agreement and shall not require either any obligation of accounting to or the consent of any Data Provider. 3.4 This Agreement imposes no obligations or restrictions on Your Use or Publication of Results. 4.1 Each Data Provider represents that the Data Provider has exercised reasonable care, to assure that: (a) the Data it Publishes was created or generated by it or was obtained from others with the right to Publish the Data under this Agreement; and (b) Publication of such Data does not violate any privacy or confidentiality obligation undertaken by the Data Provider. 5.1 All of Your rights under this Agreement will terminate, and Your right to Receive, Use or Publish the Data will be revoked or modified if You materially fail to comply with the terms and conditions of this Agreement and You do not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If Your rights under this Agreement terminate, You agree to cease Receipt, Use and Publication of Data. However, Your obligations and any rights and permissions granted by You under this Agreement relating to Data that You Published prior to such termination will continue and survive. 5.2 If You institute litigation against a Data Provider or anyone else who Receives the Data (including a cross-claim in a lawsuit) based on the Data, other than a claim asserting breach of this Agreement, then any rights previously granted to You to Receive, Use and Publish Data under this Agreement will terminate as of the date such litigation is filed. 7.1 You agree that it is solely Your responsibility to comply with all applicable laws with regard to Your Use or Publication of Data, including any applicable privacy, data protection, security and export laws. You agree to take reasonable steps to assist a Data Provider fulfilling responsibilities to comply with applicable laws with regard to Use or Publication of Data Received hereunder. 7.2 You and Data Provider(s), collectively and individually, waive and/or agree not to assert, to the extent permitted by law, any moral rights You or they hold in Data. 7.4 The Data Provider(s) reserve no right or expectation of privacy, data protection or confidentiality in any Data that they Publish under this Agreement. If You choose to Publish Data under this Agreement, You similarly do so with no reservation or expectation of any rights of privacy or confidentiality in that Data. 7.5 The Community Data License Agreement workgroup under The Linux Foundation is the steward of this Agreement (“Steward”). No one other than the Steward has the right to modify or publish new versions of this Agreement. Each version will be given a distinguishing version number. You may Use and Publish Data Received hereunder under the terms of the version of the Agreement under which You originally Received the Data, or under the terms of any subsequent version published by the Steward. 1.11 “Sui Generis Database Rights” means rights, other than copyright, resulting 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 succeeded, as well as other equivalent rights anywhere in the world.

The permissive Community Data License Agreement, version 1.0: use and publish the data, including under a licence of your choice, as long as the text of the agreement travels with it, changed files are marked and the credit of the data providers is preserved. The record follows the OdcOpenDatabaseLicense and OpenDataCommonsAttributionLicenseV10 records for its dataset target and its attribution duties, and is the first record in the library to carry dalicc:suiGenerisDatabaseRights and dalicc:moralRightsNonAssertion together.

11 findings

  • minor Rubric 1 spdx:licenseId applied

    The record carries the SPDX id CDLA-Permissive-1.0 and the SPDX name as dct:title, with the two long dashes of the licence's own name replaced by plain hyphens in dct:alternative. No dalicc:variantKind is written: version 2.0 is a different text, and it is the 2.0 record that carries the version marker.

  • major Rubric 2 odrl:target applied

    dcmitype:Dataset and dalicc:CreativeWork, because Data is defined as "the information (including copyrightable information, such as images or text), collectively or individually, whether created or gathered by a Data Provider": images and text are creative works, not only data. No software is named.

  • major Rubric 3 odrl:permission applied

    Section 2.1 grants "a worldwide, non-exclusive, irrevocable (except as provided in Section 5) right to: (a) Use Data; and (b) Publish Data", and Use is defined to include copying, adapting and computational use. The record permits reproduce, distribute, display, present, modify, derive, commercial use, derivative works, modified works and the distribution fee. dalicc:suiGenerisDatabaseRights carries section 2.2, which licenses the data "to the extent that the Data or the coordination, selection or arrangement of Data is protected or protectable under copyright, Sui Generis Database Rights, or other law". dalicc:moralRightsNonAssertion carries section 7.2, where the parties "waive and/or agree not to assert, to the extent permitted by law, any moral rights". dalicc:ChangeLicense with a cc:Notice duty and dalicc:sublicense carry section 3.1(a), "You may do so under a license of Your choice provided that You give anyone who Receives the Data from You the text of this Agreement".

  • major Rubric 4 odrl:prohibition applied

    One prohibition, dalicc:patentRetaliationTermination, from section 5.2: "If You institute litigation against a Data Provider or anyone else who Receives the Data (including a cross-claim in a lawsuit) based on the Data, other than a claim asserting breach of this Agreement, then any rights previously granted to You to Receive, Use and Publish Data under this Agreement will terminate as of the date such litigation is filed." The clause is wider than the term, which the vocabulary defines for patent claims: it covers any litigation based on the Data. It is quoted in full so the difference is readable.

  • major Rubric 5 odrl:duty applied

    Section 3.1 states the conditions for publishing, so cc:Attribution and cc:Notice hang off odrl:distribute, and odrl:modify and odrl:derive add dalicc:modificationNotice from 3.1(b), "You must cause any Data files containing Enhanced Data to carry prominent notices that You have changed those files". No cc:ShareAlike is written: this is the permissive member of the family, and section 3.2 expressly allows additional or different licence terms for Enhanced Data.

  • minor Rubric 6 dalicc:WarrantyDisclaimer applied

    Section 6.1 goes into dalicc:WarrantyDisclaimer and 6.2 into dalicc:LiabilityLimitation. dalicc:additionalClauses carries the grant, the conditions, the representations, both termination clauses, the compliance, moral rights, privacy and steward paragraphs of section 7 and the definition of Sui Generis Database Rights.

  • minor Rubric 7 cc:jurisdiction applied

    cc:jurisdiction stays dalicc:worldwide, which section 2.1 states in as many words, and dalicc:validityType stays dalicc:perpetual: the agreement names no term and calls the grant irrevocable except on the termination of section 5. The agreement names no governing law at all.

  • gap Rubric 8 dalicc:additionalClauses none

    Section 5.1 terminates the rights on an uncured material breach and keeps alive what was published before. Quoted; proposed terms dalicc:terminatesOnBreach and dalicc:sublicenseSurvival.

  • info Rubric 8 dalicc:orLaterVersionOption proposed

    Section 7.5 lets the recipient use the data under the version received or any later version published by the steward. Not written, for the reason given in the other records of this addition.

  • info Rubric 9 record none

    The consistency check of app.services.composer with the axioms of dg_default returned an empty conflict list.

  • info Rubric 10 record none

    Family: the three Community Data License Agreement records of this review group share their definitions and their warranty and liability sections. This one is the permissive member: no share-alike, a licence of your choice on publication, and attribution preserved. CDLA-Sharing-1.0 replaces 3.1(a) with reciprocity and CDLA-Permissive-2.0 rewrites the whole agreement in one page and drops the attribution condition.

Every change names the reason behind it: a finding of the content review, one of its library-wide decisions, the metadata that review wrote onto every record, or a hand edit. None of it is legal advice.

Nothing on this page is legal advice. What a license means is decided by its text; ask a legal advisor before you rely on it.
