Details
This document is a technical guide detailing the usage of various functions from older versions (pre-3) of FUME (FHIR Coverter). Key functions include $resourceId(), which returns the logical ID from a search query result, and $literal(), which retrieves the relative URL for use as a literal reference. The $search() function is used to execute actual searches against the server and receive the resulting Bundle, with options for summary mode and page size. Furthermore, the $resolve() function resolves a literal reference against the FHIR server to return the concrete resource. These functions provide fundamental technical elements necessary for applications to programmatically handle specific IDs or target references when interacting with an FHIR server.
