Bug ID: 59973
Summary: Pywikibot should have a
wikibase-error-sitelink-already-used exception
Product: Pywikibot
Version: core (2.0)
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Wikidata
Assignee: Pywikipedia-bugs(a)lists.wikimedia.org
Reporter: maarten(a)mdammers.nl
Classification: Unclassified
Mobile Platform: ---
At the moment when you try to add a sitelink to an item at Wikidata that's
already used, you'll get a pywikibot.data.api.APIError.
Sitelink to Commons Category:Mormonism based on P373
failed-save
Site link [//commons.wikimedia.org/wiki/Category:Mormonism Category:Mormonism]
is already used by item [[Q8808767]]. Perhaps the items should be
[[Help:Merge|merged]] and one of them [[Wikidata:Deletion policy|deleted]]?
Request deletion of one of the items at [[Wikidata:Requests for deletion]], or
ask at [[Wikidata:Interwiki conflicts]] if you believe that they should not be
merged.

This is a bit too low level for me. This should be caught by either site or
page and a WikiBase exception should be thrown.
The behavior should probably be modeled after the IsRedirectPage exception. We
might want to create some more Wikibase exceptions while we're at it, but I
haven't looked into that.
