SMW Relationship Mapping #175

Open WolfgangFahl opened 3 years ago

WolfgangFahl commented 3 years ago

The relationship types:

1:1
1:N
N:M

need to be handled systematically and it needs to be decided in which case the usage of subobjects is necessary to do so. See #163 for an example issue based on a relation that is 1:N in the standard case and N:M ins some rare exotic cases.

The assumption is that Instances of Entities (Objects) are handled as Pages in SMW and relations between these instances are denoted as triples

Subject Predicate Object

Where

Subject is the current Page
Predicate is defined by a Property
Object is either a Value with some valid SMW Type or another Page which might represent another Object instance or simply a Wikipage with some unstructured information.

Taking the #163 case as an example:

COMAD 2020 is the subject
Event in series is the predicate
COMAD is the object
