MetadataVersion

class tracdap.rt.metadata.MetadataVersion

Bases: enum.Enum

Explicit versioning of the metadata schema.

A strictly increasing enumeration of metadata versions. The special value CURRENT is always set to the latest version and used by default, in API calls, config files and for storing in the metadata database.

TRAC can use this information identify and handle old metadata found in the metadata database. In future it may also be possible to request old metadata versions in API calls, or to run upgrades of metadata stored in an older metadata format.

CURRENT = 1

METADATA_VERSION_NOT_SET = 0

V1 = 1
