Description

Whenever an Wikidata Lexeme object (object of type Z6005) is presented or required in the UI, we will render a special component to view, create and edit Wikidata Lexemes.

Internal representation

Wikidata Lexemes will be represented in Wikifunctions as:

• Function call to Z6xx5 with the Lexeme id as a string input (should solve T373588 first, at least deciding the function Zid):

{
  "Z1K1": "Z7",
  "Z7K1": "Z6xx5",
  "Z6xx5K1": "L1234"
}

• As per our current implementation, the string "Lxxxx" is interpreted as a valid Z6/String object in canonical form; this should remain this way.
• Whenever a Lexeme is represented in Default View, it should be only represented as a function call to Z6xx5
  • Mode selector should not allow changing to reference
  • Mode selector should not allow changing to literal

Content retrieval

Api for the Lexeme Lookup search:
https://www.wikidata.org/w/api.php?action=help&modules=wbsearchentities

Api for retrieving a Lexeme object given its Lid:
Probably the same choice as decided for T368654: Determine which API we should use to fetch Lexeme data from Wikidata when specified in the function-orchestrator

Desired behavior/Acceptance criteria

• in view mode:
  • shows the Lexeme label and links to the external wikidata reference
  • the presentation may be, initially, a link, but it can maybe contain some visual aid to communicate that this is an external link to a Wikidata Lexeme object
• in edit mode:
  • renders a selector (CdxLookup component)
  • sets the selector to whatever initial value it may have (if any)
  • allows searching and selecting from all available Wikidata Lexemes
