Hi Friedrich, I made a small .exp test to map from IFC schema/spec to SQLite

test.zip

The requirements:

1. Each TYPE and ENTITY type should be a table - without duplication (I don't care about inverses/relationships, so there's not a need to map relationships, just TYPES and ENTITY types as individual tables without mapping parent/child) - also I want to drop Ifc prefixes (IfcPerson = Person)
2. A query that shows each ENTITY holds which ENTITY types (including inverses) but it won't be a table, it'd be just a list or something like that
