Introduction

+ +

+This document serves as a collection of known DID Document properties and +property values. +

+ +
+

The Registration Process

+

+ The registration process is described in the [[[DID-EXTENSIONS]]]. +

+
+ +
+ +
+ +
+

Property Names

+ +

+The following section defines the properties available for use in a DID +document. Note that some of these properties are defined in the +DID Core Specification, and +others are defined elsewhere and may be method- or domain-specific. Please read +the associated specifications to ensure that the properties you use are +appropriate for your implementation. The properties are arranged here according +to the purpose they serve. +

+ +

+This registry is a work in progress and some properties are missing normative +definitions. We are working on this! This does NOT mean that in future it will +be possible to submit items to the registry without normative definitions (see ). +

+ +
+

DID document properties

+

+These properties are foundational to DID documents, and are expected to be +useful to all DID methods. + +

+DID +Specification Registries Issue 370 This property should be moved into a +separate suite and linked to here rather than relying on the Verifiable +Credentials vocabulary. There are known issues with the first version of the +Security vocabulary JSON-LD context and the first version of the Verifiable +Credentials JSON-LD context which will prevent these contexts from being listed +in the same document. For now it's suggested that implementers rely upon the +first version of the Verifiable Credentials JSON-LD context and not rely on +the Security vocabulary JSON-LD context in the same document. +

CredentialRegistry

+

The CredentialRegistry endpoint allows publication of a dedicated service endpoint in a DID document, through which verifiable credentials can be queried. Each registry endpoint is a REST endpoint. When a `GET` request is sent to the URI formed by appending the credentialSubject.id as a URL-encoded string to the given endpoint URI, the registry MUST return an array of verifiable credentials associated with the subject ID. A sample registry endpoint can be found here.

+

+ Verifiable credential registries are supposed to hold credentials that are publicly accessible by default, e.g., for product passports on a product type level. An additional authentication for limiting access to certain credentials is currently under development. +

DID Methods

+ +

+This table summarizes the DID method specifications currently in development. +The links will be updated as subsequent Implementer’s Drafts are produced. +This registry does not act as an endorsement of any particular DID method or its +underlying technologies by the W3C, the W3C Decentralized Identifier Working Group, +or any affiliated members of the W3C. It exists as a mechanism for developers to +discover various DID methods that they might wish to implement. +

+

+The normative requirements for DID method specifications can be found in +Decentralized Identifiers +v1.0: Methods [[DID-CORE]]. DID methods that do not meet these requirements +will not be accepted. We encourage DID method authors to provide an email +address in the Author Links column, as this helps with maintenance. +If an email address is omitted, a label noting that there is no +contact information for the author will be applied to the registry entry. +
