Expand description
Convert HL7 v2.xml XML Schema files into the JSON dictionary the
hl7-2 crates read.
HL7 publishes the v2.xml encoding as a set of XML Schema documents, and
sites that customise HL7 customise those documents: a hospital’s PID
is the standard’s PID plus or minus whatever the local system actually
sends. hl7-2 reads a dictionary rather than a schema, which is what
lets one build serve every release and every dialect — so this crate is
the bridge between the two. Point it at a directory of schemas and it
writes the dictionary that describes them.
use hl7_2_from_xsd_into_json_dictionary::{Options, convert_directory};
let document = convert_directory("schemas/paris".as_ref(), &Options::default())?;
std::fs::write("paris.json", document.to_json())?;The dictionary that comes out states cardinality as well as data types,
which is what lets hl7-2-from-er7-into-xml in schema mode produce a
document that validates against the very schemas it was built from. See
spec/index.md for the conversion rules (source of truth).
