Prohibitions

  • Change license from the text Not permitted: Change license. Replacing the license of the work, or of an adaptation, with another license, or changing its terms.

License-wide duties

  • Computational use only from the text Using the work only as the input of a computation, such as analysis, training or testing, and not publishing or performing the work itself.

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.

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.

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.

History

This license model has 2 versions. Version 2 is the one served today; every earlier version keeps its own address, so a conclusion drawn from one of them can still be checked against it.

    The changes since version 1 recorded which sentence of the text each statement rests on and named the license the record itself is published under.

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.
