RussianQuestion
I was parsing HL7 version 2.x messages through HAPI. Now I want to parse HL7 version 3 messages, which are in XML format. HAPI does not support HL7 version 3, so how can I do this?
No correct solution
OTHER TIPS
HL7 version 3 is essentially XML-formatted HL7 data. As such, you could use any old XML parser. That said, you would have to build the intelligence re: segments etc... in yourself.
It does, however, appear that there is an HL7 v3 Java Special Interest Group, which has developed an API at least for RIM.
Another option would be to look at an integration engine. An open source option here is mirth. Mirth is a interface integration engine. It is a separate product - not a library you would integrate with your own. It can, however, take over the heavy lifting of converting HL7 to something more useful in your application - a Web Service call, a database insert, a differently formatted file (pdf, edi, etc).
I used HL7 Java SIG some time ago (2008), but it is very easy to 1. create your own parser from the schemas using JAXB (Generate Java classes from .XSD files...?), or 2. create your own parser from scratch (I would suggest to use Groovy XMLSlurper http://www.groovy-lang.org/processing-xml.html).
Mohawk College publishes a Free and Open Source (FLOSS) API Framework for HL7 version 3 messaging and CDA Document processing called the "Everest Framework".
This framework is available for Java and .NET and comes with extensive examples and documentation on how to use HL7v3 messaging.
You can download the framework at (https://github.com/MohawkMEDIC/everest).
Support is also available via the GitHub project page.
This framework was developed through grant funding provided by the Natural Sciences and Engineering Research Council of Canada (NSERC) and Canada Health Infoway.
You were asking for a link to the official parser for HL7v3 (go to the section under "v3 Utilities", I'll admit it's not easy to find but here it is: http://www.hl7.org/participate/toolsandresources.cfm?ref=nav
They have some examples and data files to test with as well.
