The Open Geospatial Consortium (OGC®) membership has announced OGC’s approval of the OGC Common DataBase (CDB) specification as an OGC Best Practice.
I wonder therefore if FME should offer support for the CDB format - while it is just has a folder based structure, it is unwieldy and difficult for a human to navigate; therefore a transformer to help extract and modify data from (or to) a CDB may be beneficial.
