Standards at the core
Deep, standards-based expertise you can build on.
For two decades we have worked at the heart of healthcare interoperability — preparing specifications, especially for CDA, and supporting their implementation and testing all the way into production environments.
A recurring foundation is ART-DECOR®, the open tooling co-founded by our principal for consistent documentation, specification, implementation and testing of standards-based artefacts.
