There was a recent discussion in LinkedIn on how to produce a report that lists the set of definition types for the current encyclopedia.
Attached is a macro that writes this report to Excel. The report includes the definition types supported by the metamodel that is currently in place, along with the properties for each definition and the property types.
After installing the macro, you can run it by opening the Run Macro window (ALT-F8), then select GenerateDefnAndPropertyReport.
Hope you find this helpful.
