| 1 | | CMI FHIR Query Pattern | hl7.fhir.uv.cmi#current | R4 | A FHIR Query URL pattern that corresponds to the data specified by the data requirement. If multiple FHIR Query URLs are present, they each contribute to the data specified by the data requirement (i.e. the union of the results of the FHIR Queries represents the complete data for the data requirement). This is not a resolveable URL, in that it will contain 1) No base canonical (i.e. it's a relative query), and 2) Parameters using tokens that are delimited using double-braces and the context parameters are dependent solely on the subjectType, according to the following: Patient: context.patientId, Practitioner: context.practitionerId, Organization: context.organizationId, Location: context.locationId, Device: context.deviceId. |
| 2 | | CMI Is Selective | hl7.fhir.uv.cmi#current | R4 | Allows a given data requirement to be identified as "selective", meaning that it can be used as an additive criteria to filter a population. A selective data requirement is guaranteed to define a subset (not necessarily proper) of the initial population of a measure. If multiple data requirements are marked selective, they all apply (i.e. AND semantics). |
| 3 | | CMI Value Filter | hl7.fhir.uv.cmi#current | R4 | Allows additional value-based filters to be specified as part of a data requirement. |
| 4 | | FHIR Query Pattern | hl7.fhir.uv.crmi#current | R4 | A FHIR Query URL pattern that corresponds to the data specified by the data requirement. If multiple FHIR Query URLs are present, they each contribute to the data specified by the data requirement (i.e. the union of the results of the FHIR Queries represents the complete data for the data requirement). This is not a resolveable URL, in that it will contain 1) No base canonical (i.e. it's a relative query), and 2) Parameters using tokens that are delimited using double-braces and the context parameters are dependent solely on the subjectType, according to the following: Patient: context.patientId, Practitioner: context.practitionerId, Organization: context.organizationId, Location: context.locationId, Device: context.deviceId. |
| 5 | | FrequencyExtension - IEHR | fhir.uv.researchdatasharing#current | R4 | This Extension is used to describe how often the value specified in the DataRequirement should be transmitted |
| 6 | | FunctionExtension - IEHR | fhir.uv.researchdatasharing#current | R4 | This Extension is used to describe how requested data should be processed |
| 7 | | Is Selective | hl7.fhir.uv.crmi#current | R4 | Allows a given data requirement to be identified as "selective", meaning that it can be used as an additive criteria to filter a population. A selective data requirement is guaranteed to define a subset (not necessarily proper) of the initial population of an artifact. If multiple data requirements are marked selective, they all apply (i.e. AND semantics). |
| 8 | | Value Filter | hl7.fhir.uv.crmi#current | R4 | Allows additional value-based filters to be specified as part of a data requirement. |
