Hi Ian,

I have a reflexive many-to-many contacts relationship modelled, as you would expect through a join table. The entity is defined as follows:
attributes:
primary_key not null
relationship: string
contact_key not null
owner_key not null
relationships: contact: contact_key -> Person.primary_key (optional) on delete, nullify owner: owner_key -> Person.primary_key (optional) on delete, nullify

If your relationships are optional then the corresponding keys (contact_key, owner_key) should also be optional rather than 'not null'. That'd be a start in getting it right...

with regards,
