Property level
The properties we use ensure that we capture the correct information in a way that we can analyse it. Secundary the choice of properties supports transferability with other sdata ystems, to retrieve and to export information.
Maching properties, in order to ensure they have the same meaning, is essential for the interoperability. This can be done on different levels of accuracy:
- a property is identical. (This is the highest level of interoperability.)
- a property is more detailed, but can fall back on a more general property. (This ensures we can export towards a main system, but needs work to inport.)
Example: we use [type of information] within sources, which can fall back to [instance of]
- a property shows similar information in a different way. (This needs some work to ensure interoperability, but is feasable and accurate.)
example: we use [significant date] with a qualifier [context] and [timeline label], Wikidata uses [significant event] with a [point in time] qualifier.
- a property does not exist in other property systems. (Here interoperability is only possible if we (are allowed to) create new properties in the existing systems.)
- a property is less detailed than the existing ones in other systems. (This a situation we need to avoid.)
The relation with other systems should be documented in the property pages.

Taxonomy level
A taxonomy or controlled language is the way we define and structure things. In concreto, the taxonomies are often related to the expected values of one or more properties. For some properties, there are existing taxonomies. For other properties, we need to develop them ourselves.
In the first place we use the Wikidata taxonomies, where they usefull, and adapt them to our needs with respect for the reverse transferability.

Item level
On the level of an individual item, we try always to refer to a Wikidata item.
