Please create a new namespace called "Opera" on it.wikisource, as per this discussion:
https://it.wikisource.org/w/index.php?title=Wikisource:Bar&oldid=1534560#Lo_stato_dell.27Opera

The namespace should also have the alias "Work".

Corresponding talk namespace: "Discussioni opera", with alias "Work talk".

Please move, if possibile, the existing pages in Category:Opere to the new namespace Opera.

For further information: the pages in this namespace will be linked to the "Work items" on Wikidata. They will represent a "creative work" (a novel, a poem etc.), which is present on Wikisource in many editions. Disambiguation pages will continue to be used to disambiguate between works with same title, but we feel that they are not up to the task of disambiguating between different editions of a work.
