FAQ - DCAT with ISO/CSDGM

This FAQ provides a method for linking to a geospatial record (ISO/CSDGM) in DCAT-US 1.1 metadata for publishing into GeoPlatform.

GeoPlatform supports the publishing of ISO 19139:2007 and Content Standard for Digital Geospatial Metadata (CSDGM) metadata records. GeoPlatform can additionally support the publishing of geospatial metadata records linked within a DCAT-US record using the Distribuition and conformsTo fields. The following examples show the process for linking to geospatial records.

For more information on the GeoPlatform’s harvesting see the Data Sources FAQ.

Best practice for creating the DCAT record includes:

  • Use the downloadURL field to point to the URL that provides a direct access link to the original source metadata file.

  • Include a mediaType and format (text/xml and XML, respectively).

  • Ensure that the DCAT record title and abstract are the same as the source metadata record.

  • Include the “geospatial” theme in the DCAT record so that your dataset will be marked as geospatial in Data.gov and therefore discoverable by the GeoPlatform.

Example DCAT Snippet from “Final Critical Habitat for 24 species in Hawaii” DCAT-US record.
