General FHIR specifications

A large part of ZorgDomein Integrator is based on HL7 FHIR. This standard is based on the exchange of resources between endpoints. Resources are the common building blocks for all exchanges. The base specification of these resources is a 'platform specification', which implies that they need to be adjusted to the specific context of ZorgDomein Integrator. This is achieved by profiling: adapting the base FHIR specification to a custom use case. This way, we can create resource profiles which specify the custom implementation of FHIR resources. These profiles include rules about which resource elements are or are not used, or which terminologies are used in particular elements. Profiles may also include extensions: the additional elements that are added which are not part of the base specification. 

The following pages provide general specifications of the FHIR interface that is used in the different components.
