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)

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.

Field of use restriction: Computational Use

Clauses

Warranty disclaimer

4.2. THE 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

4.3. NEITHER DATA PROVIDER NOR ANY UPSTREAM DATA PROVIDER 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 DATA OR RESULTS, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Additional clauses

1.1. You may use, modify, and distribute the Data made available to you by the Data Provider under this C-UDA for Computational Use if you follow the C-UDA's terms. 1.2. Data Provider will not sue you or any Downstream Recipient for any claim arising out of the use, modification, or distribution of the Data provided you meet the terms of the C-UDA. 1.3 This C-UDA does not restrict your use, modification, or distribution of any portions of the Data that are in the public domain or that may be used, modified, or distributed under any other legal exception or limitation. 2.1 You agree that you will use the Data solely for Computational Use. 2.2 The C-UDA does not impose any restriction with respect to the use, modification, or distribution of Results. 3.1. You may redistribute the Data, so long as: 3.1.1. You include with any Data you redistribute all credit or attribution information that you received with the Data, and your terms require any Downstream Recipient to do the same; and 3.1.2. You bind each recipient to whom you redistribute the Data to the terms of the C-UDA. 4.1. Data Provider does not represent or warrant that it has any rights whatsoever in the Data. 5.1. “Computational Use” means activities necessary to enable the use of Data (alone or along with other material) for analysis by a computer. 5.5. “Result” means anything that you develop or improve from your use of Data that does not include more than a de minimis portion of the Data on which the use is based. Results may include de minimis portions of the Data necessary to report on or explain use that has been conducted with the Data, such as figures in scientific papers, but do not include more. Artificial intelligence models trained on Data (and which do not include more than a de minimis portion of Data) are Results.

Review

Written from the license text by: Giray Havur
Written on: 2026-09-15
Second review: not yet done
Record changed since this review: yes (version 2, 2026-09-24)
Findings: 11 recorded, 7 applied to the record, 0 proposed

The Computational Use of Data Agreement: use, modify and distribute the data for computational use, keeping the credit that came with it and binding every recipient to the same agreement. The record follows the Community Data License Agreement records of this review group, models the binding as a cc:ShareAlike duty on the acts of redistribution, and quotes the computational use restriction, which no vocabulary term can carry.

11 findings

minor Rubric 1 spdx:licenseId applied

The record carries the SPDX id C-UDA-1.0 and the SPDX name as dct:title. The library holds no other data use agreement, so dalicc:variantKind is left out; the two agreements of this review group are siblings, not versions of one another.
major Rubric 2 odrl:target applied

dcmitype:Dataset and dalicc:CreativeWork. Data is "the material you receive under the C-UDA in modified or unmodified form, but not including Results": material, not only data, and the agreement is used for text and image collections as much as for tables. No software is named.
major Rubric 3 odrl:permission applied

Section 1.1 reads "You may use, modify, and distribute the Data made available to you by the Data Provider under this C-UDA for Computational Use if you follow the C-UDA's terms." The record permits reproduce, distribute, display, present, modify, derive, commercial use, derivative works, modified works and the distribution fee. dalicc:sublicense carries the redistribution right of section 3.1, under which you bind each recipient to the terms of the agreement. dalicc:useForModelTraining is permitted because the agreement addresses it expressly: a model trained on the Data is a Result, and the agreement "does not impose any restriction with respect to the use, modification, or distribution of Results".
major Rubric 4 odrl:prohibition applied

One prohibition, dalicc:ChangeLicense, from section 3.1.2: "You bind each recipient to whom you redistribute the Data to the terms of the C-UDA." The agreement travels with the data, so the licensee cannot put the data under other terms. The use restriction of section 2.1 is not modelled as a prohibition; see the rubric 8 finding.
major Rubric 5 odrl:duty applied

Two duties on each of odrl:distribute, odrl:modify and odrl:derive: cc:Attribution from section 3.1.1, "You include with any Data you redistribute all credit or attribution information that you received with the Data, and your terms require any Downstream Recipient to do the same", and cc:ShareAlike from 3.1.2, the duty to bind each recipient to the terms of the agreement. cc:ShareAlike is the closest term the library has for that binding; it hangs off the acts, not off the odrl:Set, because it is redistribution that triggers it.
minor Rubric 6 dalicc:WarrantyDisclaimer applied

Section 4.2 goes into dalicc:WarrantyDisclaimer and 4.3 into dalicc:LiabilityLimitation. dalicc:additionalClauses carries the grant, the covenant not to sue, the public domain carve out, the restrictions section, the redistribution conditions, the representation of section 4.1 and the definitions of Data and Result.
minor Rubric 7 cc:jurisdiction applied

cc:jurisdiction stays dalicc:worldwide and dalicc:validityType dalicc:perpetual: the agreement names no governing law, no territory and no term, and no termination clause either.
gap Rubric 8 dalicc:additionalClauses none

Section 1.2 is a covenant not to sue rather than a licence: "Data Provider will not sue you or any Downstream Recipient for any claim arising out of the use, modification, or distribution of the Data provided you meet the terms of the C-UDA." It is wider than dalicc:patentGrant, which is why that permission was not written, and no term covers a general covenant not to sue. Quoted; proposed term dalicc:covenantNotToSue.
gap Rubric 8 dalicc:additionalClauses none

Section 2.1, "You agree that you will use the Data solely for Computational Use", is a field of use restriction that the vocabulary cannot express. Computational Use is defined as "activities necessary to enable the use of Data (alone or along with other material) for analysis by a computer". dalicc:useForModelTraining is not the same thing and was not stretched to cover it. The clause and its definition are quoted; proposed term dalicc:computationalUseOnly, or a general dalicc:fieldOfUseRestriction taking the field as a literal.
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 two data use agreements share every section number and most of their wording. The whole difference is that the C-UDA limits use to Computational Use and binds every recipient to its own terms, while the O-UDA restricts nothing and lets the licensee redistribute under terms of its choice. In the model that is a cc:ShareAlike duty and a dalicc:ChangeLicense prohibition on one side against a dalicc:ChangeLicense permission and a no-warranty notice duty on the other. Both sit beside the Community Data License Agreement records of this review group, which use the same vocabulary of Data, Results and Downstream Recipients.
