The French Wikisource community would be willing to experiment using lexicographical data on their project. They are already using Wikidata in templates and categories. The arbitrary access to Lexemes could be activated for this specific project.
Examples of reuse:
- in a Wikisource text, link the words to Lexemes on Wikidata to get information on the lexeme
- pass the cursor over a word to get information about its meaning
- query all the books in Wikisource containing a certain word
