In the videos I have seen about bsDD, including the one in the landing bsDD page, the example used is the one mapping the dutch classification system (NL-SfB) to IFC. It explains that an NL-SfB 22.21 Load Bearing Interior wall is mapped to an IFC object defined as IFCWall, LoadBearing = True and IsExternal = False:
But when I browse the bsDD content for this same element in the NL-SfB 2005 2.2 domain, I get this:
My issue is that the values for IsExternal and for LoadBearing are left unspecified and open. I would have expected that it would categorically say that in order to map an IFCWall to 22.21, LoadBearing needs to True and IsExternal needs to be False. Sure I can deduce the required values from the name of the 22.21 element, but this makes the dictionary, in my opinion, lacking what I understood it would provide: Clarity and an agreed unequivocal mapping. Am I missing something? Actually, I could not find any example in any of the other Domains where it would have some sort of decisive mapping to BuildingSmart pset property values.
