Appendix 1 - Default Namespace

hcpsdk is primarily targeting the authenticated Namespaces invented with HCP version 3.

Nevertheless, it is possible to use hcpsdk with the legacy Default Namespace by taking notice of a few differences:

  • As there is no user authentication with the Default Namespace, use the hcpsdk.DummyAuthorization class as the authorization argument when instantiating an hcpsdk.Target
  • Different from authenticated Namespaces, the root folder for requests is /fcfs_data (instead of /rest)
  • An HEAD request for an object stored in the Default Namespace will yield very limited object metadata, only. If you need more, you need to request the metadata by a GET from /fcfs_metadata/your/path/to/object/core-metadata.xml
  • The Default Namespace can have a single annotation (custom metadata), only. You need to request it by a GET from /fcfs_metadata/your/path/to/object/custom-metadata.xml
  • Several actions you can trigger by a POST request to an authenticated Namespace need to be executed by a PUT to one of the files in /fcfs_metadata/your/path/to/object/.


Consult the manual Using the Default Namespace available from the HCP System and Tenant Management Consoles for details about working with the Default Namespace.
