Welcome to the Polar Data Catalogue Metadata API

Swagger Logo

This API is aimed at facilitating harvest and acquisition of PDC metadata. A variety of endpoints are available to eliminate the need for bulk harvest and subsequent filtering. PDC currently offers metadata in two formats:

  • JSON-LD: This is the default format, structured to be compliant with schema.org standards.
  • XML: This is an optional format, structured to be compliant with ISO 19115 standards.

General usage documentation is provided below, including setup instructions, a step-by-step user guide, and an advanced section with code snippets. Developers can Fast Track to the API Endpoint Specifications described on our Swagger page.
