We need to specify:
* the "language" of a Lexeme
* the "language" of each Term of a multi-variant lemma (and Term representation, and Sense glosse)
There are essentially two options for representing a language or variant:
* an ISO code
* a Q-Item reference (possibly mapped to an ISO code somehow)
There are several kinds of variants, mainly:
For representing lemmas (and representations and glosses) in HTML and RDF, we need ISO language codes. We can put ISO codes int Statements of items about languages, but then these statements must not change. We can make up ISO codes from Q-Ids, e.g. qqd-Q7832478, but that's not very useful, since consumers don't understand them.
