Are there any *standard* vocabularies that provide a descriptor for usernames/screennames/handles?

Question

For example, consider a subset of the user data provided by the Twitter API:

{
    "id_str": "6253282",
    "screen_name": "twitterapi",
    "name": "Twitter API"
}

Let’s say I want to model this information with JSON-LD. I can easily adapt most of this data using standards like:

• JSON-LD’s built-in @id attribute
• Schema.org’s name attribute
• RFC 7565’s acct URI scheme

{
    "@id": "acct:6253282@twitter.com",
    "???": "twitterapi",
    "http://schema.org/name": "Twitter API"
}

(The ??? is a placeholder for the descriptor I’m seeking.)

In short: are there any standard vocabularies that I could use to replace the ??? in the code snippet above?

Answer 1

The vocabulary FOAF¹ provides the nick property:

A short informal nickname characterising an agent (includes login identifiers, IRC and other chat nicknames).
