But if the class is contained within a template instance only within
some technical background information and it is not part of the
reference model, how can a query mechanism like AQL use this information
during query execution ?
How does an AQL query engine know that an archetype based on Composition
is a Composition when this link is given in the RM-part of the
serialized instance only within the archetype_id of the
archetype_details ? From that it could deduced by using the background
knowledge of the available archetype definitions that it is in fact a
Composition. It would be easier if this would be directly included in
the RM-part of a serialized Composition itself.
Or is the class type something one would assume as part of the RM ?
Greetings
Georg
