Hello All,

I have created a separate excerpt document here based on today's agreement
to extract the Vocabulary as a separate document
https://docs.google.com/document/d/1xQrBwK5tiggSWMXh7ByZ4acEjtMaIMgqyQey67fh5TQ/edit?usp=sharing
<https://docs.google.com/document/d/1xQrBwK5tiggSWMXh7ByZ4acEjtMaIMgqyQey67fh5TQ/edit?usp=sharing>

I created the document through my personal google account
mark.leuba@gmail.com so you should have access without issue.  Here is a
copy inline.

Thanks!  -Mark

The Credentials VocabularyEntities

Credential - a claim from an entity(s) that denotes qualification,
achievement, quality, or other pieces of information about an entity’s
background such as a name, government ID, payment provider, home address,
or university degree.

Recipient  - also known as the credential-owner or credentialee, an entity
<http://opencreds.org/specs/source/use-cases/#dfn-entity> that is in
control of a particular credential
<http://opencreds.org/specs/source/use-cases/#dfn-credential>; who is
typically both the primary subject of the information in a credential and
the entity that initiates its transmission.

Issuer - an entity <http://opencreds.org/specs/source/use-cases/#dfn-entity>
that creates and assigns credentials
<http://opencreds.org/specs/source/use-cases/#dfn-credential> to recipients.

Requestor - an entity
<http://opencreds.org/specs/source/use-cases/#dfn-entity> that requests a
credential <http://opencreds.org/specs/source/use-cases/#dfn-credential>
from a recipient.

User agent - a program, such as a browser or other Web client, that
mediates the communication between the recipient and the requestor
<http://opencreds.org/specs/source/use-cases/#dfn-requestor> on behalf of
the a credential recipient.

Credential Service - a program, such as a credential
<http://opencreds.org/specs/source/use-cases/#dfn-credential> storage vault
or personal credential wallet, that stores and protects access to an
credentialee's
<http://opencreds.org/specs/source/use-cases/#dfn-credentialee> credentials
and can, on request, provide secure access to Requestors.  The software
process involved is known as the Credential Agent.

Credential Agent - secure access of a credentialee’s credentials to a
requestor is done through a credential agent

Endorser - an entity, such as a witness or another organization, that
provides assurances of the value or validity of a credential.

Classes

Claim - a property value pair, where the issuer asserts one quality or
attribute of a credential earner or of an achievement attributable to the
earner. The property name takes the form of an IRI, dereferencable to a
term definition. Claims may be gathered into claim sets.

Credential Class - a specific defined set of claims intended to be issued
as an unchanging set to many recipients. A credential class may be specific
to one issuer or shared between multiple issuers. It contains the
properties of the credential that apply to all its recipients.

Credential Instance - A credential class as issued to one recipient by one
issuer, packaged in digital form to be reliably verified with a
cryptographic signature. It encapsulates the credential class’s claims, but
it also includes properties that apply specifically to the recipient’s
credential, such as its date of issue, and claims particular to the earner,
such as a unique identification number.

Credential Collection - A composition of multiple credentials earned by one
recipient. A collection may be assembled by their recipient for
transmission initiated by that recipient, or may be dynamically composed
upon a requestor’s petition. Credential recipients direct Credential
Services how to respond to requests, which requestors are permitted to see
different credentials, and whether recipient approval is required before
responding to a request.

Identity - An IRI acts as a common identifier for an identity, which can
serve as Issuer, Recipient, Endorser or Requestor of credentials. See the
Identity Credentials spec draft.

Properties

Credentials vary from one another based on the identity of the issuer and
recipient, and the properties that define their content. Properties may
apply to issuers, to credential classes or to credential
instances/recipients.
