1 | Dublin Core | DC Definition | DCAT | CKAN | Proposal | Notes |
2 | contributor | An entity responsible for making contributions to the resource. | dct:contributor | extra:contributor | Add support for contributor to the CKAN DCAT plugin | Not part of standard CKAN DCAT plugin |
3 | coverage | The spatial or temporal topic of the resource, spatial applicability of the resource, or jurisdiction under which the resource is relevant. | dct:coverage; dcat:spatial; dcat:temporal | extra:spatial_uri + extra:spatial + extra:spatial_text; extra:temporal_start + extra:temporal_end; extra:coverage | For CKAN/DCAT to coverage, use a text description of the spatial and temporal characteristics e.g. "Bounding lat-lon [53, -4.5],[50, 1.7]. 2022-01-01 - 2022-12-31" For DC->DCAT/CKAN, store coverage as dct:coverage/extra:coverage without attempting to generate dcat:spatial and dcat:temporal. Note that extra:coverage is not part of the standard CKAN DCAT plugin | Lack of definition for coverage makes mapping DC->DCAT or CKAN problematic. |
4 | creator | An entity primarily responsible for making the resource. | dct:creator | extra:creator | Add support for contributor to the CKAN DCAT plugin | Not part of standard CKAN DCAT plugin |
5 | date | A point or period of time associated with an event in the lifecycle of the resource. | dct:date or dct:issued | extra:issued | Map date to the issed date of the dataset dct:issued | The DC "date" field definition makes it impossible to infer how it is being used. |
6 | description | An account of the resource. | dct:description | notes | ||
7 | format | The file format, physical medium, or dimensions of the resource. | dct:format | resource:format | ||
8 | identifier | An unambiguous reference to the resource within a given context. | dct:identifier | extra:identifier (synonyms - extra:guid, extra:id) | ||
9 | language | A language of the resource. | dct:language | extra:language | ||
10 | publisher | An entity responsible for making the resource available. | dct:publisher | extra:publisher_uri | ||
11 | relation | A related resource. | dct:relation | extra:relation | Store in the CKAN extra:relation field unmodified | Not part of standard CKAN DCAT plugin. CKAN has its own "relations" structure that is complex to map to this one |
12 | rights | Information about rights held in and over the resource. | dct:rights or dct:license | resource:rights or resource:license | For CKAN/DCAT to DC use dct:rights if available, otherwise dct:license | The rights may include license and copyright elements. They are combined in DC but separate in DCAT and CKAN. For DC->CKAN/DCAT use rights. |
13 | source | A related resource from which the described resource is derived. | dct:source | extra:source | ||
14 | subject | The topic of the resource. | dct:keywords | tags | For DC->DCAT/CKAN store in dct:keywords/tags For DCAT/CKAN->DC concatenate dcat:keywords/tags and dcat:theme e.g. dcat:theme: "assets" dcat:keywords: "132kV, tranformer" -> dc:subject: "assets, 132kV, transformer" | |
15 | title | A name given to the resource. | dct:title | title | ||
16 | type | The nature or genre of the resource. | dct:type | extra:dcat_type | ||
