Localisation is searching the sources that (might) have relevant information on the client. Localisation on a broad level is done via an interface Mitz offers. This means the GtK should offer Mitz Connector functionality when an explicit patient consent is necessary for the information exchange the GtK supports.
With the so-called open authorization query a healthcare provider can ask Mitz which other healthcare providers maintain records of a certain client may and can be consulted for one or more data categories. The result gives 0 or more healthcare providers (identified with URA) that have client consent to share the requested datatype and might have it. The URA-identifier in combination with the type of electronic service(s) that need to be addressed can be used as search parameter to find corresponding Twiin GtK interfaces in ZORG-AB (see addressing).
