This document serves as an official registry for all known global parameters, properties, and values used by the Decentralized Identifier ecosystem.

This registry is under active development and implementers are advised against using the registry unless they are directly involved with the W3C DID Working Group.

Comments regarding this document are welcome. Please file issues directly on GitHub, or send them to public-did-wg@w3.org ( subscribe, archives).

Introduction

This document serves as an official registry for all known global parameters, properties, and values used by the Decentralized Identifier ecosystem.

The Registration Process

Software implementers might find that the existing Decentralized Identifier Core specification [[DID-CORE]] is not entirely capable of addressing their use case and might need to add a new parameters, properties, or values to this registry in order to achieve their use case in a globally interoperable fashion. In order to add a new parameter, property, or value to this registry, an implementer MUST submit a modification request for this registry, as a pull request on the repository where this registry is hosted, where the modification request adheres to the following policies:

  1. Any addition to the DID Core Registries MUST specify a human readable description of the addition.
  2. If there are copyright, trademark, or any intellectual property rights concerns, the addition and use MUST be authorized in writing by the intellectual property rights holder under a F/RAND license. Examples include DID Methods that use trademarked brand names, property names that utilize the titles of copyrighted works, and patented technology that would cause the use of the extension to require licensing a patent.
  3. Any addition MUST NOT create unreasonable legal, security, moral, or privacy issues that will result in direct harm to others. Examples of unacceptable additions include any containing racist language, technologies used to persecute minority populations, and unconsented pervasive tracking.
  4. Any addition to the DID Core Registries MUST link, via at least a URL, preferably a content-integrity protected one, to the defining specification so that implementers can implement the property.
  5. Any addition to the DID Core Registries that is a property or value, MUST specify a machine readable JSON-LD Context for the addition.
    • The JSON-LD Context MUST be included in full as part of the submission.
    • A namespace URI MUST be provided for the JSON-LD Context so that consumer implementations can consistently map a URI to the full context.
    • The URI provided MUST be persistent, and link all terms to their associated human readable descriptions.
    • The URI provided SHOULD resolve or link to the full context contents.
    • JSON-LD Contexts MUST be versioned and MUST NOT be date stamped.
    • JSON-LD Contexts SHOULD use scoped terms and MUST use the @protected feature to eliminate the possibility of term conflicts.
  6. Properties in the DID Core Registries MUST NOT be removed, only deprecated.

The Editors of the DID Specification Registries MUST consider all of the policies above when reviewing additions to the registry and MUST reject registry entries if they violate any of the policies in this section. Entities registering additions can challenge rejections first with the W3C DID Working Group and then, if they are not satisfied with the outcome, with the W3C Staff. W3C Staff need not be consulted on changes to the DID Specification Registries, but do have the final authority on registry contents. This is to ensure that W3C can adequately respond to time sensitive legal, privacy, security, moral, or other pressing concerns without putting an undue operational burden on W3C Staff.

Entries that are identified to cause interoperability problems MAY be marked as such at the discretion of the maintainers of this registry, and if possible, after consultation with the entry maintainer.

Any submission to the registries that meet all the criteria listed above will be accepted for inclusion. These registries enumerate all known mechanisms that meet a minimum bar, without choosing between them.

The Labeling Process

This section describes labels that are used to categorize registry entries.

Deprecated
This label is applied to registry entries that should not be relied on.
No Contact Info
This label is applied to registry entries for which no point of contact has been provided.

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.

ISSUE 240 on DID Core: The duplication and/or possible interaction of properties held in a JWK and a verification method are an active topic of discussion in the Working Group. Implementers are cautioned that the behavior of values associated with this property are not stable and might change in the future.

Do not include private or extraneous information in verification methods. The class of private information related to JWKs is defined here.

DID Methods

This table summarizes the DID method specifications currently in development. The links will be updated as subsequent Implementer’s Drafts are produced.

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.
