ODA Common Data Access (CDA) API provides direct access to BimRv element properties and BimRv database structure information (meta-data) at runtime.
The Common Data Access API is based on the Kernel SDK runtime system extension — the RxProperties mechanism — and is fully independent of a BimRv database.
The Common Data Access API for BimRv SDK is implemented as a wrapper for parameters contained in a BimRv project and is based on a special representation of
a BimRv database structure that is close to the IFC tree representation.
