Support asset "roles" for STAC in Data Catalog data Searches
Closed this issue · 5 comments
STAC results from DAPA ciurrently utilize the asset keys of "data", "metadata", "browse", and a few others. This does not allow for the support of multiple data values without knowing their keys. To work around this, the asset key should be unique (based on the asset filename) and the asset-role will be added to indicate the type of data: https://github.com/radiantearth/stac-spec/blob/master/item-spec/item-spec.md#asset-roles
This means the code here:
https://github.com/unity-sds/unity-py/blob/main/unity_sds_client/services/data_service.py#L67-L71
Will need to be updated to A) iterate over the stac assets and create DataFiles instead of looking specifically for a asset with key data.
- STAC asset key is not based on "data" or "metadata" - should be unique and not known ahead of time
- STAC asset role is used to define data, metadata, etc. (https://github.com/radiantearth/stac-spec/blob/master/item-spec/item-spec.md#asset-roles )
- Ingest commands can ingest multiple "data" role types successfully
- unity-py properly supports asset role (https://github.com/radiantearth/stac-spec/blob/master/item-spec/item-spec.md#asset-roles )
- file a ticket with CMR to use the asset-role in their results
