Schema-Driven Generation of Synthetic HL7 FHIR RDF Data from Shape Expressions (ShEx)

<p>We describe how synthetic HL7 FHIR data in RDF was produced directly from Shape Expressions (ShEx), using the authoritative FHIR R4 ShEx schema as the sole source of domain structure. Rather than encoding clinical knowledge in a domain-specific simulator, we drive generation from the published shapes: a schema-driven generator (rudof generate) consumes them, and a small configuration file controls scale, cardinalities, and value generation. This note reports the method---schema selection, a minimal schema preparation step, the generator configuration, and the invocation---so that the process is reproducible.</p>
