Замечания

The ExternalMetadataColumnCollection property contains a collection of IDTSExternalMetadataColumn100 columns. This optional collection is populated by components that connect to external data sources and is used to maintain a snapshot of the columns from the external data source. The external metadata columns can then be used to validate the columns in the output column collection when the component is in a disconnected state.
