Spec: https://review.openstack.org/#/c/98554/14/specs/juno/metadata-schema-catalog.rst
According to metadata definition spec, properties can include readonly flag (field), but in current implementation this information is not returned by the API v2.
Example seed which defines readonly flag is located at etc/metadefs/compute-host-capabilities.json and following properties are setup as non-readonly:
- cpu_info:topology:cores
- cpu_info:topology:threads
- cpu_info:topology:sockets
To reproduce this issue simply send GET request to Glance API v2 and query for OS::Compute::HostCapabilities namespace. Properties which defines readonly flag (shown above) has no information about it displayed in result.
Sample URL: http://localhost:9292/v2/metadefs/namespaces/OS::Compute::HostCapabilities
