Form Template Field Mapping Extension

Canonical../StructureDefinition/nexus-form-template-field-mapping
Statusdraft · 1.26.0
BaseExtension (constraint)
ContextDocumentReference (element)
SourceFSH · JSON

Which fillable fields of a form template's file a chart value pre-fills. One rule per field: the field's name in the file, verbatim, and the chart value that fills it, coded from the form chart value vocabulary (patient.lastName, patient.birthDate.year, patient.address.city, ...). A form started from the template opens with each mapped field filled from the patient's chart and every value still editable; a field the mapping does not name, or whose chart value cannot be resolved, is left blank.

Extension

Short Which fillable fields of the template's file a chart value or a fixed value pre-fills, as the default fill template and any named ones
Definition Which fillable fields of a form template's file a chart value pre-fills. One rule per field: the field's name in the file, verbatim, and the chart value that fills it, coded from the form chart value vocabulary (patient.lastName, patient.birthDate.year, patient.address.city, ...). A form started from the template opens with each mapped field filled from the patient's chart and every value still editable; a field the mapping does not name, or whose chart value cannot be resolved, is left blank. Rules are keyed by field name because a fillable PDF may draw one named field on several pages, and every widget carrying the name is filled. The mapping is carried only by a template (a DocumentReference marked under NamingSystem/nexus-form-template); a filed form carries the filled values in its own file and needs no mapping.

Short Additional content defined by implementations
Definition May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Comments Extensible rather than required: the vocabulary is expected to grow, and a deployment may carry a key ahead of this specification listing it. A reader that does not know a key leaves the field blank -- an unfilled box, never a wrong value -- so an unknown key degrades safely. Carried instead of staticValue, never beside it.
