From translatewiki.net

This form label is for the input field for the wiki identifiers. Users may type one or more identifiers here.

Identifiers can be a language code (e.g. 'de' will assume the German Wikipedia), or a database code (enwiki_p for English Wikipedia), hostname (fr.wiktionary, optionally including ".org") and some others as well. Almost any form of identification or guessing is accepted.
