 ## DCAT-AP to LinkML translation

+The [official DCAT-AP 3.0.0 SHACL shapes](https://github.com/nfdi-de/dcat-ap-plus/blob/main/src/dcat_ap_plus/dcat_ap_shacl.jsonld) where downloaded from the DCAT-AP GitHub repository
 from the [3.0.0 release folder within the master branch](https://github.com/SEMICeu/DCAT-AP/blob/master/releases/3.0.0/shacl/dcat-ap-SHACL.jsonld). We chose this shapes definition file, as they are in line with the current DCAT-AP Specification website and because its IRI resolves. It must be noted, that this is not case for the shapes provides in the GitHub 3.0.0 release
 (respectively the release branch).
