Abstract
This article describes the architecture of a framework for integrating medical information using Health Level Seven and FHIR. An iterative programming methodology was followed along with the incremental approach. The following steps have been done in order: the exchange format type is established, the terminologies, code systems and value sets, to be used are established, mappings that will be used are established, set the RESTful API over HTTP, gather all the FHIR resources required, set URLs for the search, set URLs for the operations, establish asynchronous usage, Design of communications with rest of systems, coding and testing and establish profiling. In conclusion, a framework was designed and developed to enable interoperability in different medical information systems, all this through the use of the international standards HL7 and FHIR, and taking into account certain lessons learned from previous works related to the area.
