Main components:
- Wikidata configuration
User story:
As a new Wikidata editor, I would like to quickly see which parts of an Item define the Wikidata ontology.
Problem:
As is, our users are often not aware that some of their edits on Items are modifying the Wikidata ontology. This unintentionally leads to an overly complex and inconsistent ontology. We need to improve this situation.
Solution:
A first step would be to introduce a dedicated section on Item and Property pages for classifying properties. This section is named "Classification" and it will live above the statements section. This dedicated section will make it more obvious that some properties modify the ontology.
List of properties:
The proposed section will contain the following properties:
- https://www.wikidata.org/wiki/Property:P279 (subclass of)
- https://www.wikidata.org/wiki/Property:P31 (instance of)
- https://www.wikidata.org/wiki/Property:P361 (part of)
- https://www.wikidata.org/wiki/Property:P1647 (subproperty of)
Origin: https://www.wikidata.org/wiki/Wikidata:Item_classification
- https://www.wikidata.org/wiki/Property:P1709 (equivalent class)
- https://www.wikidata.org/wiki/Property:P3950 (narrower external class)
- https://www.wikidata.org/wiki/Property:P2888 (exact match)
- https://www.wikidata.org/wiki/Property:P1382 (partially coincident with)
- https://www.wikidata.org/wiki/Property:P2670 (has parts of the class)
- https://www.wikidata.org/wiki/Property:P527 (has part)
- https://www.wikidata.org/wiki/Property:P3113 (does not have part)
- https://www.wikidata.org/wiki/Property:P2737 (union of)
- https://www.wikidata.org/wiki/Property:P2738 (disjoint union of)
- https://www.wikidata.org/wiki/Property:P2445 (metasubclass of)
- https://www.wikidata.org/wiki/Property:P1963 (properties for this type)
- https://www.wikidata.org/wiki/Property:P3176 (uses property)
- https://www.wikidata.org/wiki/Property:P1889 (different from)
- https://www.wikidata.org/wiki/Property:P460 (said to be the same as)
- https://www.wikidata.org/wiki/Property:P2959 (permanent duplicated item)
- https://www.wikidata.org/wiki/Property:P1269 (facet of)
- https://www.wikidata.org/wiki/Property:P2860 (cites work)

Notes:
- This first step will only involve the display of statements after saving. We might consider making deeper changes to the UI and recommendation system at a later time, based on user experience with this change.
Acceptance criteria:
- Wikidata is reconfigured in a way so that the described properties will show up as a dedicated section above the statements section on Item and Property pages.
Open questions:
- Should some properties be removed from this dedicated section?
- Should some properties be added to this dedicated section?
Community communication:
We would like to get community feedback via the Project Chat before implementing this change. If possible, we should also ping the community members that originally discussed this idea.
Original:
This idea came up at Wikidata Data Quality Days, WikidataCon pre-conference, and the WikidataCon session on ontology issues.
