- Record Locator Service (RLS)
The Record Locator Service (RLS) maintains an index of the locations of
patient records for each person in the system. Clinical information is
never sent to the RLS. Furthermore, the RLS only stores secured, blinded
demographic information necessary for record linking. When a patient is
registered with an institution, a query is submitted to the RLS. The RLS
returns the location of any matching records. A location consists of a
site identifier and a record identifier specific to the remote site.

- Peer to Peer Data Exchange (PtPE)
Finally, the located data interchange is managed purely between the adapters
amongst institutions using encrypted web services.
