FHIR (Fast Healthcare Interoperability Resources) is a new set of HL7 healthcare standards. Its main focus is on the ease of implementation, based on RESTful HTTP using XML or JSON. Components called "Resources" are used to store and exchange data between systems. The resources are just XML or JSON documents following a standard definition, and include the actual resource data (like patient demographics), metadata, tags, and a human-readable description. However they are also fully extensible, meaning that additional implementation-specific data elements can be added if needed. For more information, visit: FHIR Overview
Since Mirth Connect has HTTP connectors and supports XML/JSON data, you might have already guessed that creating a fully-compliant FHIR implementation has already been completely possible. What this technology preview provides is an even easier way for you to kick-start your new interface. The new FHIR Listener connector acts much like an HTTP Listener (that's what FHIR is based on after all), but also includes an assortment of FHIR-specific settings as well as some helper/utility classes for working with responses.
Note that at the time of writing, the latest officially released draft of FHIR is Draft Standard for Trial Use (DSTU) 2. Later drafts of the standard may not be 100% compatible with this technology preview, but we will endeavor to create new previews when newer versions of FHIR are officially released.
