A more specific sub-property SHOULD be used if the nature of the relationship of the link is known. The property dcat:distribution SHOULD be used to link from a dcat:Dataset to a representation of the dataset, described as a dcat:Distribution

Revised usage note:

dcterms:relation SHOULD be used where the nature of the relationship between a cataloged resource and related resources is not known. A more specific sub-property SHOULD be used if the nature of the relationship of the link is known. The property dcat:distribution SHOULD be used to link from a dcat:Dataset to a representation of the dataset, described as a dcat:Distribution

Following #1532, update in the for 6.4.9 Property: language

Current Usage Note:

"In the context of DCAT 2.0, if representations of a dataset are available for each language separately, define an instance of dcat:Distribution for each language and describe the specific language of each distribution using dcterm:language (i.e. the dataset will have multiple dcterm:language values and each distribution will have just one as the value of its dcterm:language property).

New Usage Note:

If representations of a dataset are available for each language separately, define an instance of dcat:Distribution for each language and describe the specific language of each distribution using dcterms:language (i.e., the dataset will have multiple dcterms:language values and each distribution will have just one as the value of its dcterms:language property). In case of multilingual distributions, the distributions will have multiple dcterms:language values.
