It could be of benefit to be able to generate a hash of any number of fields and have this included in the schema for the connector. Could be of benefit to allow this to be used as the key of the connector, and to be used for relationships.
Obviously the UI will have to be updated to accomodate, as would the config files and adapter/factory pairs. The schema provider may have to be updated to allow for these hashes to be suggested, depending on how the configuration is done.
The hash must always calculate the same for the same input, differently should the same values be swapped between two of the fields, and be resilient to clashes.
