The table below lists the operations HCP supports and indicates which protocols you can use to perform those operations. Some operations relate to specific types of metadata. For more information on this metadata, see Object properties.

Store, replace, or delete an annotation for an object |
✓ | |||

Store or retrieve object data and an annotation in a single operation |
✓ | |||
Store or retrieve object data and the default annotation in a single operation |
✓ | |||
Check for annotation existence |
✓ | |||
Check for existence of the default annotation |
✓ | ✓ | ||
List annotations |
✓ | |||
Read an annotation |
✓ | |||
Read the default annotation |
✓ | ✓ | ✓ | ✓ |
Store, replace, or delete an ACL for an object |
✓ | |||
Check for ACL existence |
✓ | ✓ | ||
Read ACLs |
✓ | ✓ | ✓ | ✓ |
Create an empty directory in a namespace |
✓ | ✓ | ✓ | ✓ |
View the namespace directory structure, not including metadirectories |
✓ | ✓ | ✓ | ✓ |
View the namespace directory structure, including both directories and metadirectories |
✓ | ✓ | ✓ | |
Rename an empty directory (unless atime synchronization is enabled) |
✓ | ✓ | ✓ | |
Delete an empty directory |
✓ | ✓ | ✓ | ✓ |
Create a symbolic link |
✓ | ✓ | ||
Read through a symbolic link to an object |
✓ | ✓ | ✓ | ✓ |
Delete a symbolic link |
✓ | ✓ | ✓ | ✓ |
List the namespaces accessible to you |
✓ | |||
List namespace statistics |
✓ | |||
List namespace permissions for the user |
✓ | |||
List the retention classes available in the namespace |
✓ |
These considerations apply to symbolic links:
•If you use CIFS to create a symbolic link, you can read through the link only with CIFS. You cannot use CIFS to read through a symbolic link created with NFS.
•HTTP and WebDAV support for reading through symbolic links is limited to retrieving object data. Other HTTP and WebDAV operations on symbolic links may produce unexpected results.

Tip: You can use the HCP Search Console to delete, purge, hold, release, change ownership, or modify ACLs on multiple objects with a single operation. |
