The IPS Reference Implementation Server is built to support the International Patient Summary (IPS) through an adaptation of the HAPI FHIR 
project, which is a 100% open-source (Apache 2.0 Licensed) Java based implementation of the FHIR specification.
This server supports a HL7 FHIR R4 $summary operation to retrieve a document Bundle that conforms to the FHIR Implementation Guide for IPS . You can load data using standard FHIR R4 API interactions and generate new summaries. The server has been pre-loaded with a set of example patients to demonstrate IPS documents. This server and the supporting code are under active development and may change.
