NIST/ITL is collaborating with industry to define standards-based approaches to clinical document registries. We are collaborating on the project 'Integrating the Healthcare Enterprise' (IHE), an industrial effort with a focus on interoperability of healthcare systems. NIST/ITL is a primary author of the IHE Profiles: Cross-Enterprise Document Sharing Family. NIST/ITL has also developed a reference implementation for the XDS profile and a web-based test suite, allowing vendors to determine conformance to the XDS profile. Vendors also use the test suite as an early stage tool for interoperability testing.
The reference implementation is available as an open source project hosted on Source Forge, called IheOs (i.e., IHE Open Source), at http://iheos.sourceforge.net. The test suite is available at http://ihexds.nist.gov/.
