Catalog Record |
| Definition |
A record in a catalog, describing the registration of a single dcat:Resource. |
| Hierarchy |
|
| Usage note |
This class is optional and not all catalogs will use it. It exists for catalogs where a distinction is made between metadata about a dataset or service and metadata about the entry in the catalog about the dataset or service. For example, the publication date property of the dataset reflects the date when the information was originally made available by the publishing agency, while the publication date of the catalog record is the date when the dataset was added to the catalog. In cases where both dates differ, or where only the latter is known, the publication date SHOULD only be specified for the catalog record. Notice that the W3C PROV Ontology [[PROV-O]] allows describing further provenance information such as the details of the process and the agent involved in a particular change to a dataset or its registration. |

| Usage note |
The class of all cataloged resources, the super-class of dcat:Dataset, dcat:DataService, dcat:Catalog and any other member of a dcat:Catalog.
This class carries properties common to all cataloged resources, including datasets and data services.
The instances of this class SHOULD be included in a catalog.
When describing a resource which is not a dcat:Dataset or dcat:DataService, it is recommended to create a suitable sub-class of dcat:Resource, or use dcat:Resource with the dcterms:type property to indicate the specific type.
dcat:Resource is an extension point that enables the definition of any kind of catalog. Additional sub-classes may be defined in a DCAT profile or other DCAT application for catalogs of other kinds of resources. |

| Usage note |
In relation to the use case of data citation, when the cataloged resource is a dataset, the dcterms:isReferencedBy property allows to relate the dataset to the resources (such as scholarly publications) that cite or point to the dataset. Multiple dcterms:isReferencedBy properties can be used to indicate the dataset has been referenced by multiple publications, or other resources.
This property is used to associate a resource with the resource (of type dcat:Resource) in question. For other relations to resources not covered with this property, the more generic property dcat:qualifiedRelation can be used. See also 15. Qualified relations. |

| Usage note |
Information about licenses and rights SHOULD be provided on the level of Distribution. Information about licenses and rights MAY be provided for a Dataset in addition to but not instead of the information provided for the Distributions of that Dataset. Providing license or rights information for a Dataset that is different from information provided for a Distribution of that Dataset SHOULD be avoided as this can create legal conflicts. See also guidance at 9. License and rights statements. |

| Usage note |
dcterms:license, which is a sub-property of dcterms:rights, can be used to link a distribution to a license document. However, dcterms:rights allows linking to a rights statement that can include licensing information as well as other information that supplements the license such as attribution.
