dcterms:rights, dcterms:accessRights, and dcterms:license in Darwin Core
by John Wieczorek 29 Dec '13

29 Dec '13

Dear all, Bob Morris recently submitted an issue [1] to the Darwin Core code site showing a potential ambiguity in the inclusion from Dublin Core of both dcterms:rights and dcterms:accessRights in the Simple Darwin Core schema [2]. The ambiguity arises from the fact that dcterms:accessRights is actually a subclass of dcterms:rights. Looking at the Darwin Core documentation about the use of these terms, I noticed that dcterms:rights [3] suggests a license ("http://creativecommons.org/licenses/by-sa/3.0/") as an example. I think this example is an inappropriate use for the term and instead is an example of a dcterms:license. I think it would be a good idea to add dcterms:license to the list of terms promoted by Darwin Core, especially after reading Peter Desmet's blog posts [4, 5]. If license was indeed the intent for including dcterms:rights in the first place, then perhaps it can be deprecated, leaving only its subtype dcterms:accessRights. Discussion welcome, so that I know whether to submit an issue for these changes to the Darwin Core.
