No, that is not a data model. It is an exported record. If it were a data model you could tell if this was a "date" type, a "time string" or a "character string". In this case none are apparent. (as a hint, in this system it means that due to the fact you can't have an empty datetime attribute, all default on creation to 2000/01/01 and when this object is updated it actually gets a UNIX time string but that is irrelevant to the discussion). --tim
