v19 v20 174 174 EHR Service Model 175 175 176 176 177 The EHR service model defines the coarse-grained interface to electronic health record service. The level of granularity is openEHR Contributions and Compositions, i.e. a version-control / change-set interface. 178 179 177 180 178 181 Part of the model defines the semantics of server-side querying, i.e. queries which cause large amounts of data to be processed, generally returning small aggregated answers, such as averages, or sets of ids of patients matching a particular criterion. … … 182 185 Archetype Service Model 183 186 187 188 184 189 The archetype service model defines the interface to online repositories of archetypes, and can be used both by GUI applications designed for human browsing as well as access by other software services such as the EHR. 190 191 185 192 Terminology Interface Model 193 194 186 195 187 196 The terminology interface service provides the means for all other services to access any terminology available in the health information environment, including basic classification vocabularies such as ICDx and ICPC, as well as more advanced ontology-based terminologies. Following the concept of division of responsibilities in a system-of-systems context, the terminology interface abstracts the different underlying architectures of each terminology, allowing other services in the environment to access terms in a standard way. The terminology service is thus the gateway to all ontology- and terminology-based knowledge services in the environment, which along with services for accessing guidelines, drug data and other "reference data" enables inferencing and decision support to be carried out in the environment.
