The x: namespace

@prefix x: <https://x-cli.tamnd.com/ns#> .

x rdf writes schema.org wherever a term exists and x: where none does. This page is the x: half. It is served at the namespace URL itself, so a triple store that follows its nose from x:repliesTo lands here.

Nothing on this page is an invention where schema.org already had a word. A reply is not a schema:comment, because a comment is a different thing on a different kind of page; a repost is not a schema:sharedContent, because that is what was shared and not the act of sharing. Where the fit was close enough, the mapping uses schema.org and this page says nothing at all: schema:author, schema:mentions, schema:citation, schema:keywords, schema:associatedMedia, schema:sameAs, schema:location, schema:containedInPlace, schema:memberOf.

Classes

Term	What it is
x:Conversation	A thread, identified by the id X gives the whole conversation rather than any one post in it.
x:Hashtag	A hashtag, lowercased, without the #.
x:Cashtag	A ticker symbol tag, lowercased, without the $.
x:Trend	One trending topic, in one place, at one moment. All three parts are part of the identity.
x:Poll	A poll attached to a post.
x:Card	A link preview card: the title, description, and image X renders for a URL.
x:CommunityNote	A Community Note attached to a post.

Properties

Term	Domain to range	What it says
x:repliesTo	post to post	This post is a reply to that one.
x:reposts	post to post	This post is a repost of that one.
x:inConversation	post to conversation	This post belongs to that thread.
x:taggedSymbol	post to cashtag	This post carries that ticker tag.
x:hasPoll	post to poll	This post carries that poll.
x:hasCard	post to card	This post carries that link preview.
x:hasNote	post to note	This post carries that Community Note.
x:pinned	account to post	This account has pinned that post to its profile.
x:follows	account to account	The first account follows the second. A followers listing and a following listing both normalise to this, pointing the way the claim points.
x:liked	account to post	This account liked that post.
x:reposted	account to post	This account reposted that post.
x:owns	account to list	This account owns that list.
x:hosted	account to space	This account hosted that Space, or created it.
x:spokeIn	account to space	This account held the microphone in that Space. Not x:hosted, because a speaker is not an admin.
x:joined	account to dateTime	When the account was created. schema:dateCreated describes the page rather than the person, so this is its own term.
x:state	space to text	X's own word for what became of a Space: Running, Scheduled, Ended, TimedOut, Canceled. Not normalised, because a Space that timed out and one the host ended are different events and only X knows which happened.

Counters

Engagement counts are not x: terms. They are schema:InteractionCounter, which is what X itself publishes in the microdata on every status and profile page, so the counts a crawl produces line up with the counts X states:

<x://tweet/20> schema:interactionStatistic [
  a schema:InteractionCounter ;
  schema:interactionType schema:LikeAction ;
  schema:name "Likes" ;
  schema:userInteractionCount 307403
] .

Followers use schema:interactionStatistic and follows use schema:agentInteractionStatistic, which is the same split X makes: one is something done to the account, the other is something the account did.
