FHIR-MHD Transport Pattern Mapping Notes
- FHIR REST API (in least in theory) is based on OMG Health RESTful specification
- http://www.omg.org/spec/HData/1.0/PDF/
- on first inspection, it does not seem to cause incompatibility issues with existing use of REST in MHD.
- the recommendation of using CORS has impact on HTTP level: http://enable-cors.org/. Discussed in http://www.hl7.org/implement/standards/fhir/security.html
HTTP verbs used for basic operations on resources in FHIR
- POST - create
- PUT - update
- DELETE - delete
- GET - read
There are some exceptions to this scheme: the "transaction" operation utilizes POST to create or update a set of resources (resource bundle) atomically.
Mapping of FHIR operations to existing XDS transactions
Transaction operation
This operation can facilitate Provide & Register Document Set-b (ITI-41, ITI-42) and "Update Document Set" (ITI-57) transactions. It can create and update a set of resources (authors, documents) in one transaction:
- If entry.content is omitted, the resulting operation is closer to Register (ITI-42).
- If entry.id refers to an existing resource, it mimicks "Update Document Set"
