Looking for a library to process CDA (AKA HL7v3, AKA CCD) messages in Java

Question

I am working on processing CDA messages for a Java application. CDA is yet another XML standard for sending medical information, it is closely related to CCD and HL7v3.

I have already reviewed the following libraries and found them lacking, promising, but lacking.

• JAXB - Feed it a CDA XSD and let it generate classes. It'll work, but it doesn't really provide much more than a Java layer to access the XML
• HL7 JavaSIG from Regenstreif - Promising, but half the project appears to be hidden under the label "encumbered" with little information about how to gain access or get that data through proper channels.
• MDHT - Early releases, tightly bound to the modeling tools in Eclipse. Seems like it'll work, but very steep learning curve.

I do have access to resources at HL7.org.

Any ideas for other libraries to look at? Communities to visit to ask experts?

Answer 1

You might find this project more focused (e.g. less learning curve than MDHT)

https://openhealthworkbench.projects.openhealthtools.org/

Answer 2

Two options are creeping to the top of my list:

MDHT - mdht.projects.openhealthtools.org/ Braid - http://braid.sourceforge.net

MDHT has a lot of extras on it beyond what one NEEDS to produce or consume and utilize CDA/CCD messages. Braid is purportedly proven, having participated in a few IHE Connectathons.

I'll keep posting here until I give up or find an answer.

It is infuriating that these standards are published without a useful reference library in a major language, but thats another thread.

i also meet this problem, can you tell me how you solved this issue finally?
