FAQ - GeoPlatform Linked Open Data

Linked Open Data are structured data interlinked that is understandable by machines and humans.

GeoPlatform’s GeoNetwork provides formatters to transfrom metadata into the JSON-LD, RDF DCAT, and DataCite Linked Data Schemas.

Getting GeoPlatform’s metadata record UUID

GeoPlatform creates a unique UUID for every metadata in GeoPlatform. The UUID for each record can be gotten from the URL or from the page view of the metadata record.


DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web.

GeoPlatform GeoNetwork RDF DCAT End Point

The RDF DCAT end point provides a way of getting information about the catalog, the datasets and services, and links to distributed resources in a machine-readable format. The formats of the output are based on DCAT, an RDF vocabulary that is designed to facilitate interoperability between web-based data catalogs.


The following URLs are available:

https://geonetwork.geoplatform.gov/geonetwork/srv/eng/rdf.search?: returns a dcat:Catalog record. By default this will describe all the records in the catalog, but query filters are available (see below)

https://geonetwork.geoplatform.gov/geonetwork/srv/eng/rdf.metadata.get?uuid= : returns an RDF record for the given UUID

JSON-LD (JSON for Linking Data)

JSON-LD is a lightweight Linked Data format. It is easy for humans to read and write. It is based on the already successful JSON format and provides a way to help JSON data interoperate at Web-scale. JSON-LD is an ideal data format for programming environments, REST Web services, and unstructured databases such as Apache CouchDB and MongoDB.


The follow API is available:

https://geonetwork.geoplatform.gov/geonetwork/srv/api/records/<UUID>/formatters/jsonld : returns an RDF record for the given UUID


The DataCite Metadata Schema is a list of core metadata properties chosen for an accurate and consistent identification of a resource for citation and retrieval purposes, along with recommended use instructions.


The follow API is available:

https://geonetwork.geoplatform.gov/geonetwork/srv/api/records/<UUID>/formatters/datacite : returns an DataCite record for the given UUID
