Form Population

View the page here: http://hl7.org/fhir/uv/sdc/populate.html

Population operations

• $populate
• $populate-html

Smart Forms only supports full population at the moment, and SMART App Launch is a requirement. Only patient, practitioner and encounter launch contexts are supported.

Population mechanisms

• Observation-based
• Expression-based
• StructureMap-based

While StructuredMap-based population mechanism is not supported, sdc-questionnaire-sourceQueries is supported, using an expression-based approach.

Form Data Extraction

View the page here: http://hl7.org/fhir/uv/sdc/extraction.html

This is something we are super interested in, but haven't quite got to it yet.

Modular Forms

View the page here: http://hl7.org/fhir/uv/sdc/modular.html#modular-questionnaires

Our Forms Server https://smartforms.csiro.au/api/fhir supports the $assemble operation. The implementation is based on http://hl7.org/fhir/uv/sdc/modular.html#modular-questionnaires.

Adaptive Forms

View the page here: http://hl7.org/fhir/uv/sdc/adaptive.html

This is not something on our radar at the moment :(
