Altova is well known for it's flagship product XMLSpy - as anyone who has worked extensively with XML data can tell you. However, they have an entire suite of product offerings, one of which is MapForce. As described on it's website:
A typical Healthcare Information Exchange (HIE) accepts data from an array of disparate sources. Often the data it accepts is semantically and syntactically altered by a providing system to satisfy interfacing requirements. However, there are also cases where data from different sources need to be properly merged before reaching the HIE's interface.
It’s been about a year and half since we first released Intel® SOA Expressway for Healthcare, which is a purpose-built, easy-to-deploy integration appliance for connecting islands of information together to enable a secure, high-performance, best-of-breed health information infrastructure. We have now begun shipping release 2.2, which contains a number of new feature enhancements.
