migrate(obj: Dict[str, Any], version: pystac.serialization.identify.STACVersionID, info: pystac.serialization.identify.STACJSONDescription) → None[source]#: Migrate a STAC Object in dict format from a previous version. The base implementation will update the stac_extensions to the latest schema ID. This method will only be called for STAC objects that have been identified as a previous version of STAC. Implementations should directly manipulate the obj dict. Remember to call super() in order to change out the old ‘stac_extension’ entry with the latest schema URI.

abstract property prev_extension_ids: Set[str]#: A set of previous extension IDs (schema URIs or old short ids) that should be migrated to the latest schema URI in the ‘stac_extensions’ property. Override with a class attribute so that the set of previous IDs is only created once.

abstract property schema_uri: str#: The schema_uri for the current version of this extension

abstract property stac_object_types: Set[pystac.stac_object.STACObjectType]#: A set of STACObjectType for which migration logic will be applied.
