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.","action":"none"}],"family":"Use of data agreements","port_of":null,"variant_kind":null,"notes":"Modelled from the SPDX plain text. cc:legalcode points at the agreement on the site of the Community Data License Agreement project, which publishes both agreements, rather than at the source repository named first in the SPDX seeAlso list; dct:source points at the SPDX page the text was taken from. dct:publisher is left out: the text names no steward.
