GDC Data Dictionary


The GDC Data Dictionary defines components of the GDC Data Model and relationships between them.

Data Dictionary Viewer

The GDC Data Dictionary Viewer is a user-friendly interface for accessing the dictionary. It includes the following functionality:

  • Dictionary contents: Display of entities defined in the dictionary, including their descriptions, properties, and links.
  • Links to semantic resources: Links to semantic data resources that define Common Data Elements (CDEs) used in the dictionary
  • Submission templates: Generation JSON and TSV templates for use in GDC data submission.

Entity JSON Schemas

In technical terms, the dictionary is a set of YAML files that define JSON schemas for each entity in the dictionary. The files are available on GitHub.

The GDC API can generate entity JSON schemas in JSON format. The API also provides the template generation functionality accessible via the GDC Data Dictionary Viewer. See API documentation for details on how to access these functions programmatically.
