<h1>Introduction</h1>
<p>
This document serves as an official registry for all known global parameters,
properties, and values used by the Decentralized Identifier ecosystem.
</p>
</section>
<section>
<h1>The Registration Process</h1>
<p>
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 Github Pull Request, where
the modification request adheres to the following rules:
</p>
<ol>
<li>
Any addition to the DID Core Registries MUST specify a human readable
description of the addition.
</li>
<li>
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.
</li>
<li>
Any addition to the DID Core Registries that is a property or value, MUST
specify a machine readable JSON-LD Context for the addition.
</li>
<li>
Any addition to the DID Core Registries that is a JSON-LD Context MUST link
all terms to the associated human readable description.
</li>
<li>
Any addition to the DID Core Registries MUST specify a non-normative JSON Schema
(the specification is normative) for the addition.
</li>
<li>
Properties in the DID Core Registries MUST NOT be removed, only deprecated.
</li>
<li>
JSON-LD Contexts MUST be versioned and MUST NOT be date stamped.
</li>
<li>
JSON-LD Contexts SHOULD use scoped terms and MUST use the @protected feature to
eliminate the possibility of term conflicts.
</li>
</ol>
<p>
Additions that do not meet these criteria MUST NOT be accepted. 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.
