When editing a regular wiki page as an anon, there's a message saying that the IP will be saved and made public. This is important for data protection/transparency, and may even be required by law in some regions. We need to show such a warning on the wikibase repo too. Perhaps the message could slide in at the top of the page when the user first enters edit mode. There could be a dismiss [x], which would set a cookie to disable the message. Doesn't work with JS, but hey, nother does editing...
Could use the notification system that has recently been added to MediaWiki.
The ordinary notification is sufficient, but he should not be notified more than once and not unless he tries to edit. The message box will be automatically removed so an explicit dismiss is probably not necessary. There could be a problem if the session is terminated while the page is open, then the notification could fail. If the user edits from a page he opened while he was logged in, he should get a session failure and be asked to log in again before he can edit.
