Can HAPI FHIR be used to parse HL7v3 messages?

[MaS]

Hey everyone!

I'm just starting to dive into the topic and haven't found a similar question here, so I hope this is not redundant.

The software I'm developing will soon need to provide an interface that allows external software to push HL7v3 messages to our system, reads those messages and creates database entries based on them. Ideally, I'd love to use HAPI FHIR for that; since FHIR is backwards compatible to HL7v3, I would hope that it's possible, but I'd like to confirm (or disprove) this before I start playing around with it.

Can anyone help me out?

Thanks a lot!

HL7 FHIR and HL7 v3 are different standards families, and don't actually share much design similarity. Unfortunately there is no concept of backwards compatibility between them, and as a result HAPI FHIR definitely can't parse HL7v3 payloads.

There are a few tools out there that try to create libraries for working with HL7 v3 (one example would be Eclipse MDHT: https://projects.eclipse.org/projects/modeling.mdht ). I haven't used any of them personally though. For what it's wortth, any time I've ever had to parse v3 payloads, I've just used the XSDs to generate JAX models and worked with those. It's clunky, but if you're only trying to extract data it's not so bad.

Cheers,

James

The FHIR standard pages do maintain a set of informational mappings from FHIR to the RIM. For example, see this one for Patient: http://hl7.org/fhir/patient-mappings.html#rim

However, FHIR is not based on the RIM so there is no tooling available to automatically apply these mappings as far as I know.

It looks old XML parsers are workable . I am interested in a Web Service call.
