Table 258 · Entries in a permissions dictionary
ISO 32000-1:2008, §12.8.5 · PDF page 485 ↗
/UR3 dictionary
(Optional) A signature dictionary that shall be used to specify and validate additional capabilities (usage rights) granted for this document; that is, the enabling of interactive features of the conforming reader that are not available by default. For example, A conforming reader does not permit saving documents by default, but an agent may grant permissions that enable saving specific documents. The signature shall be used to validate that the permissions have been granted by the agent that did the signing. The signature dictionary shall contain a Reference entry that shall be a signature reference dictionary that has a UR transform method (see 12.8.2.3, “UR”). The transform parameter dictionary for this method indicates which additional permissions shall be granted for the document. If the signature is valid, the conforming reader shall allow the specified permissions for the document, in addition to the application’s default permissions.
Qualifier: Optional
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
