Modelling/Humans


Modeling humans

The focus on Metabase is not on individuals, but rather on what they produce. For this reason, we limit the information about people to what's needed to link them to their products.

We only create items about human (Q23) when these are needed to describe authorship/speaker/event or project responsibility. And only when this information is already publicly available, any affiliation would also need to have been publicly communicated. Since the main affiliation might not always apply, it can be superseded by a qualifier on an item-by-item basis.

Examples

Names

Some Wikimedians participate in the movement's activities and are widely known under their usernames only. Do respect that and do not publish their real name if you happen to know it but they have not made a public connection between it and their username

Others maintain separate user accounts for their participation as affiliate staff and volunteers. It can for example happen that one person has two presentations at a conference, one as affiliate staff and another in their volunteer capacity. If the source material makes the distinction clear – e.g. the conference program says one presentation is given by Sven Svensson (WMSE) and the other by Sven123456, do create two person items, even if you happen to know whom the volunteer account belongs to.

Modeling human roles

The following properties are used to add humans to items:

Properties used

ONLY the following properties are ever allowed on a human. This is to minimize the personal data that is stored.

Required Property Example value Notes
REQUIRED instance of (P5) human (Q23)
IF EXISTS same as on Wikidata (P1) Q68773375
ONLY if no same as on Wikidata (P1) affiliation (P34) Wikimedia Sverige (Q9) Should be the main affiliation of the person. Can be overridden on a case-by-case basis with a qualifier if needed. Can also have start time (P6), end time (P7) qualifiers if later affiliations are relevant for the linked data.
