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.

RDF DCAT¶

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.

URLS

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.

API

The follow API is available:

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

DataCite¶

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.
