When mapping COBie attributes to Revit parameters, there needs to be a way to map to built-in Revit parameters such as Manufacturer. - Is it possible to obtain the GUID of built-in parameters? Maybe with [RevitLookup](https://github.com/jeremytammik/RevitLookup)? - Is there a fully itemized list of Revit system parameters and OOTB family parameters somewhere?
