WP1: Requirements analysis
it is very important to first define the
exchange scenarios / uses cases
of the IFC extensions to be developed
otherwise the data model might fail to fulfill
the requirements coming from these uses cases
consensus must be found regarding the use cases
to be supported
use case identification was based on the results of
the IFC-Infra Overall Architecture project
