FHIR libraries

Reference libraries

We use FHIR in 3 projects in the reference stack

1. HIP Service: Where we pack the data in FHIR formats. The reference HIP Service is a .net project and we use the FHIR C# reference library.
2. HIU Service: Where we unpack and process the FHIR data. Reference HIU is written in Java and we use the HAPI Library
3. HIU Interface: We started using the fhir.js, but ended up writing our own simplistic javascript processing library, as we anyway get the data in FHIR json format from the HIU backend service and we do not make any resource specific call (e.g. create data)

There are tons of really useful resources listed in the FHIR website.

• Reference implementations - check out the reference implementation section.
• Open source implementations - provides other libraries written in Delphi, PHP, Python, JavaScript etc

FHIR Validator

Before you go too far ahead and break your head about why is your data is not accepted or displayed, its a good idea to keep validating the resources that you compose. You can use the following tools (again from the FHIR website)

• Reference FHIR resource validator (Java)
• Online FHIR resource validator
