Currently, the toolkit allows a user to create the specification and associated with the model. How about being able to generate the specification based on model elements? Generally, we find early in a project LOD/LOI is defined at a high level, it is not until the design is underway until the specifics are specified, at this point, we generally already have a model with defined components.
Linking the uniclass2015 codes to IFC class and enumerations will help close the 'inconsistency-gap' between specifiers and designers.
