Modeling a document

There are many possible types of document (Q21). See the list of available types.

When a new document type is needed, it should have subclass of (P4) = document (Q21) (see white paper (Q47)), or subclass of (P4) = more specific type (see final report (Q76) which is a type of report (Q29)).

Document types are expected to have a same as on Wikidata (P1), though special cases that are not relevant for Wikidata are imaginable.

Linking topics and projects

A document should have one or more main subject (P15) to describe what it's about, e.g. linked open data (Q70). The value of this statement can be an index term (Q12) (topical keyword), an activity/event (a report from an edit-a-thon), a project (a report from a project), an organization, a Wikimedia content project (Q22)...

The more subject keywords we add, the easier it becomes to run nuanced searches and analyses.

A document that was produced within the scope of a particular project, as is the case with documents produced by WMSE, should link to this project with produced in the scope of the project (P36).

Note that documents like application (Q43), which are directly related to a particular project, but were not created during this project, will have the project as main subject (P15) but not as produced in the scope of the project (P36) (because an application is published before the project has started).
