Declare a list of xattr keys TODO the below comment is currently copied from the owncloud driver, revisit Currently,extended file attributes have four separated namespaces (user, trusted, security and system) followed by a dot. A non root user can only manipulate the user. namespace, which is what we will use to store ownCloud specific metadata. To prevent name collisions with other apps We are going to introduce a sub namespace "user.ocis.".

Functions

func ReferenceFromAttr

func ReferenceFromAttr(b []byte) (*provider.Reference, error)

ReferenceFromAttr returns a CS3 reference from xattr of a node. Supported formats are: "cs3:storageid/nodeid".
