.NET EDIFACT/X12 Framework

Question

We need to process some EDI messages for a client and i was wondering if any of you could recommend some components (not necessarily free) that could do the task. I'm interested in a framework that can parse EDI messages into .NET structures and some kind of implementation of transport protocols (SMTP, FTP, HTTP, AS2) etc.

Answer 1

There is a open source .NET x12 parser at http://x12parser.codeplex.com that has been around for a while and is pretty mature now. It already supports over 15 transaction sets including most of the ones in HIPAA set. It's pretty extendable for injecting your own specification, instructions for this are on the site. Check out the site for an html serialization of the parsed X12 message.

The nice thing that I like is that it allows you to unbundle your X12 into separate X12 messages so that you can process them individually. For instance if you want to unbundle claims you just have to unbundle it by the loop ID "2300". It will reserialize your X12 in an indented format so it is easier to reader. For example the following is an 837 claim after it has been parsed into an Interchange object and then serialized with whitespace:
