4.6 Names and Descriptions

When displaying a credential, it can be helpful to have text provided by the issuer that furnishes the credential with a name and a short description of its purpose. The name and description properties serve these purposes.

      name

An OPTIONAL property that expresses the name of the credential. If present, the value of the name property MUST be a string or a language value object as described in 11.1 Language and Base Direction. Ideally, the name of a credential is concise, human-readable, and could enable an individual to quickly differentiate one credential from any other credentials they might hold.

      description

An OPTIONAL property that conveys specific details about a credential. If present, the value of the description property MUST be a string or a language value object as described in 11.1 Language and Base Direction. Ideally, the description of a credential is no more than a few sentences in length and conveys enough information about the credential to remind an individual of its contents without having to look through the entirety of the claims.

[Example 5](https://www.w3.org/TR/vc-data-model-2.0/#example-use-of-the-name-and-description-properties): Use of the name and description properties
