Interoperability Land™

Immersive Environment for the Health Sector and beyond

Interoperability Land™ (IOL) is a collaborative, digital platform designed to power the future of interoperability. Based on Meld, an open-source sandbox populated with fully synthetic FHIR® data, IOL offers a hosted ‘private locker’ immersive environment to advance industry solutions for private sector companies, technology incubators, start-up companies, and academic endeavors.

IOL is a cloud-hosted, collaborative digital platform and test bed that supports an HL7® FHIR®-based simulated healthcare ecosystem with highly realistic synthetic data to enable advanced interoperability testing and development across different organizations and systems. A solution enabler, testing environment, community support platform and technology incubator. Learn more…
