Hi all,
I just noticed that we have a number of "orphaned items" which were
created and imported from some Wikipedia article that then got deleted.
The result is an item with almost no data, no sitelinks, and all
references claiming "imported from X Wikipedia".
Example:
https://www.wikidata.org/wiki/Q9386774
Here is what happened:
https://www.wikidata.org/w/index.php?title=Q9386774&action=history
It would be good to have a process for dealing with such cases. I am not
saying that we must delete such items immediately, but it seems obvious
that they need some special attention to become self-sustaining even
without Wikipedia articles associated.
Things that would be important to keep such items:
* Links to other external datasets that confirm the existence of the thing.
* Links to authoritative web sites that confirm the existence of the thing.
* Proper references for all data (we always want that, but here it's
even more critical: "imported from Wikipedia" is never great, but at
least it leaves some hope of finding proper references if the Wikipedia
page still exists).
In cases like the above, deletion seems to be the most reasonable
solution (the little data that is there can easily be added again if
needed in the future). It seems that one could automatically collect
such candidates for deletion (pages that are not used as property
values, have no site links, have no identifier properties, were not
edited since more than a month, an have less than, say, ten
properties+labels+descriptions).
Regards,
Markus
