This documents illustrates the mappings defined in GeoDCAT-AP, as implemented in the iso-19139-to-dcat-ap.xsl XSLT.
- Used namespaces
- Reference code lists for metadata elements
- Mapping summary
- Mappings of individual metadata elements
For a number of INSPIRE metadata elements, this document proposes the use of URI code list registers. These registers include:
- Code lists defined in the INSPIRE Metadata Regulation [INSPIRE-MD-REG], and made available through the URI registers operated by the INSPIRE Registry [INSPIRE-REGISTRY].
- URI registers operated by the Publications Office of the EU, whose use is recommended in DCAT-AP.

The following sections provide a summary of the alignments defined in GeoDCAT-AP.
The alignments are grouped as follows:
- Alignment for metadata records (metadata on metadata)
- Alignments for resource metadata common to datasets, series and services
- Alignments for resource metadata specific to datasets and series
- Alignments for resource metadata specific to services
The alignments supported only in the extended profile of GeoDCAT-AP are in bold.
The domain of the mappings is dcat:CatalogRecord, with the exception of metadata standard title and version, whose domain is dct:Standard.

The metadata standard is modelled with dct:Standard, and it is described by a title and a version - see below |

As a rule, the domain of the mappings is either dcat:Dataset, dcat:DatasetSeries or dcat:DataService / dcat:Catalog (when the element is used for services). However, “starred” elements – i.e., elements whose name is preceded by an asterisk (“*”) – are those having as domain either dcat:Distribution (when the element is used for datasets and series) or dcat:DataService / dcat:Catalog (when the element is used for services).
