LINKING OF RECORDS
If a receiving agency wishes to link data from different sources, including administrative sources, investigations into the legal practicality of undertaking such a process will need to occur. If all legislative requirements are met and data linking can occur then rules for dealing with inconsistencies across records for the same entity need to be developed. Rules for dealing with records not exactly matched on the basis of unique identifiers also need to be developed in order to be able to use various pieces of information together. One of the difficulties with administrative data is the lack of consistency and coherence with other sources which is needed in order to undertake data linking.
