Object properties

Objects in a namespace have a variety of properties, such as a retention period and an index setting. These properties are defined for each object by the object metadata. HCP maintains both HCP-specific and POSIX metadata for objects. You can view all the metadata for objects in a namespace and modify some of it.

HCP maintains only POSIX metadata for directories and symbolic links.

The namespace configuration specifies default values for several object properties. When you store an object in the namespace, the object inherits these values. You can override some of these values when using the HTTP protocol to store objects in the namespace.

If only the HTTP protocol is enabled for a namespace, the namespace can be configured to allow objects to have multiple versions.

This chapter provides detailed information about objects and their properties. It covers HCP-specific metadata, POSIX metadata, object versions, custom metadata, and ACLs.

For information about using the HTTP protocol to retrieve a complete list of metadata for an object, see Checking the existence of an object or multiple versions of an object.

With the WebDAV, CIFS, and NFS protocols, HCP displays object metadata in metafiles. For information about these metafiles, see Metafiles.

For the WebDAV protocol, HCP also provides its own XML namespace with live properties that allow you to store and retrieve HCP system metadata. For more information about these properties, see HCP-specific metadata properties for WebDAV.
