Hello.

Is there a common or crosswise vocabulary strategy when suggesting new Predefined type enumerations (i.e. ISO/DIS 6707-1)? I see the risk of increasing inconsistencies when including new options due to the previous lack of Schema definitions.

Thanks for the updates.

Hi David,

very good point! Thank you for that.

Indeed we should take that into account. In this case all new elements should go through review anyways. IFC schema and domain experts are requested to do so.

Regards
