DID Document (JSON)
(
)
16. A DID Document is a JSON-LD serialization of a DID Entity (14). A DID Document has a set of attributes that includes the following: id (DID) (13) service (endpoints) authentication publicKey @context etc. The id (DID) attribute (13) is the unique identifier or key for the DID Document. The id (DID) attribute is given the nickname “DID” (aka Decentralized Identifier) for convenience; but more importantly, to clarify what a DID specifically refers to (as well as to clarify what the term DID specifically does not refer to). “DID” should only be used to refer to the id (DID) attribute of a DID Entity (14) (or DID Document). id (DID) are used to index, find, and retrieve DID Documents from the Technology Layer (30). id (DID) exists as an attribute of a DID Entity (14) (and by implication, as an attribute of DID Document, the JSON-LD serialization of the corresponding DID Entity).
