Interface to Data Dictionary (Delphi 3)

Does anyone have any idea about how to interface with the Delphi 3 Data
Dictionary? Looking at the structure of the tables doesn't give me any
clues - it looks like the information is in BLOB fields. Delphi 2
apparently shipped with a Case Expert tool which vendors could supply a
DLL for, but this wasn't included in D3.

Any help on this matter would be greatly appreciated.
