Earth Data Hub Catalogue

Catalogue for the Earth Data Hub project within the EU Destin Earth initiative. This catalogue is aimed at producing a STAC API implementation and defines a simplified version of the STAC specification as a schema for its objects, written as JSONSchema in the schema/ folder.

Assumptions

The data in this repository needs to respect the following assumptions:

• The catalogue files and folders must be located inside the catalogue/ folder;
• Each folder in catalogue/ represents a collection and each of its folders represents a dataset (corresponding to a STAC item) associated to that collection;
• Collections and datasets are univoquely identified by their folder names;
• Collections and datasets metadata are written as YAML files (respectively __collection__.yaml and __item__.yaml) inside their relative folders and must respect the simplified version of the STAC specification defined in the schema/ folder;
• Thumbnail images and description files can be written as URL inside the YAML files or added to the collections and datasets folders;
• The schemas for the collections and datasets files are defined inside the schema/ folder as JSONSchema files;
• Additional files and folders used by external tools can be contained inside collections and datasets folders.

STAC Extensions

The STAC extensions adopted in the catalogue are listed below:

• Earth Data Hub (schema/extensions/earthdatahub.json)
• Dublin Core (schema/extensions/dublincore.json)
• Datacube
• xarray Assets
