I enhanced DataBasin object's describe. First, I do parse the RecordTypeInfo now, but that was the easy part. Salesforce.com returns only the record type ID and name, but programmatically, this is not very useful. The important bit would be the Developer Name of each record type.
I enhanced the results by querying automatically the RecordType table, extracting the Developer Name, matching it through the RT Id and merging back the results, so that the resulting DBSObject has a complete Record Type information, totally transparent.
