Hi everyone,
At Wikimania we had several discussions about the future of Wikidata and
Commons. Some broader feedback would be nice.
Now we have a property "Commons category"
(
https://www.wikidata.org/wiki/Property:P373). This is a string and an
intermediate solution.
In the long run Commons should probably be a wikibase instance in it's
own right (structured metadata stored at Commons) integrated with
Wikidata.org, see
https://www.wikidata.org/wiki/Wikidata:Wikimedia_Commons for more info.
In the meantime we should make Commons a wikidata client like Wikipedia
and Wikivoyage. How would that work?
We have an item
https://www.wikidata.org/wiki/Q9920 for the city
Haarlem. It links to the Wikipedia article "Haarlem" and the Wikivoyage
article "Haarlem". It should link to the Commons gallery "Haarlem"
(
https://commons.wikimedia.org/wiki/Haarlem)
We have an item
https://www.wikidata.org/wiki/Q7427769 for the category
Haarlem. It links to the Wikipedia category "Haarlem". It should link to
the Commons category "Haarlem"
(
https://commons.wikimedia.org/wiki/Category:Haarlem).
The category item (Q7427769) links to article item (Q9920) using the
property "main category topic"
(
https://www.wikidata.org/wiki/Property:P301).
We would need to make an inverse property of P301 to make the backlink.
Some reasons why this is helpful:
* Wikidata takes care of a lot of things like page moves, deletions,
etc. Now with P373 (Commons category) it's all manual
* Having Wikidata on Commons means that you can automatically get
backlinks to Wikipedia, have intro's for category, etc etc
* It's a step in the right direction. It makes it easier to do next steps
Small change, lot's of benefits!
