Complete coding for NHIN Direct may be done this month

What comes out will not just be a code dump, but a reference implementation with complete documentation.

Arien Malec writes about real progress on the creation of NHIN Direct, a system that would let health files ride securely and efficiently on existing Internet infrastructure.

"I've come to realize that for basic interoperability, the value of a high quality, production ready, open-source implementation is critical," Malec writes. Specifications and documentation are less important than a reference implementation.

So that is what the NHIN Direct team has now focused on.

Malec offered the chart at the right, showing the group's progress. In less than a month the team has gone from about 10,000 lines of code to over 25,000 lines. And a substantial portion of that code has undergone unitest testing.

The chart includes both C# .Net and Java implementations of the reference design, Malec adds. The comment count line (it's in red) represents Javadoc/C# XML comments that generate API documents. Installation guides and other documentation are also being produced alongside the code.

"We are aiming for the end of this month to be code complete for all the major components," he concludes, and what comes out will not just be a code dump, but a reference implementation with complete documentation.
