For this there are some TCA properties that were originally meant for 
IRRE (Inline Relational Record Editing) [1].

For use in Extbase you need to adjust the model. You need a model for 
the relationship in which you can include the additional properties.
This is a bit explained in [2] and a demonstration extension is 
available in [3].

To explain it a bit, let's use the example of relationships (like 
marriage, living together, etcetera) between people. If you take this on 
an international level, there can be a relationship with more than one 
person.
So, you make a model for the relationship, add fields for the 
relationship type and other properties and map this to the MM table.

 From one person you can read the relationships and for each 
relationship look at the properties of the attached person.
