fhirserver

Reference Implementation Server for the FHIR Specification.

Basic Information

This is a FHIR server + utilities written in Delphi. It is also the home of the pascal reference implementationfor FHIR. Included in this project:

• The Delphi reference implementation for FHIR (/reference-platform)
• A set of tests for the delphi reference implementation
• The FHIR reference server (supports the entire FHIR functionality, along with OAuth, OpenID.Connect, and SCIM)
• The FHIR Notepad++ plug-in - a set of useful utilities for FHIR developers

For binary releases of this content, see http://www.healthintersections.com.au/FhirServer

This project is maintained by the FHIR Project lead. The server runs in multiple locations, including http://test.fhir.orgg and other places.

Reference Server

In form, this a middleware tool to help applications exchange data via a repository. It shows how to implement a generic FHIR server against an SQL database. The server is specifically written as an reference server - it implements all parts of the specification as defined, and is co-developed with the specification. It is not well optimised for hosting/supporting very large repositories efficiently.

Libraries

The open source FHIR Server includes delphi/pascal implementations of:

• Xml/XPath/XML Patch
• JSON/JSONPointer/Json Patch
• OAuth/openID Connect (including google/facebook clients) + JWT/JWK support
• Turtle format (RDF)
• GraphQL
• SCIM
• LOINC/SNOMED/RxNorm/CVX/UCUM
• CQL (Clinical Query Language)
• All of FHIR + FHIRPath + smart all launch + cds-hooks, of course

Compiling

This is pascal code that (in principle) compiles under Delphi XE3+ (any edition, personal will do). Note that in practice, various subtle but breaking changes have been introduced to the runtime library (Streams, Indy) that mean that some fiddling with IFDEFs may be necessary.

Support for Free Pascal(/Lazarus) would be good, but requires substantial work to deal with the difference between delphi and FPC implementations of pascal. Contributions are welcome

The FhirServer depends on the following other GitHub repositories: https://github.com/grahamegrieve/delphi-markdown https://github.com/VSoftTechnologies/DUnitX

You need to get a copy of these and fix the paths for the markdown processor units in the .dprs. You also need to get a copy of the latest version of the Indy components, since the server depends on some recent fixes to Indy. note you don't need to install them - just put them in your system path. (Tools...Options)

And also you need to install https://bitbucket.org/sglienke/testinsight/wiki/Home (all delphi users should have this installed!)

After that, compiling should be simple: open the file fhirprojects.groupproj in your version of delphi, and compile all projects

Note that the FHIRServer is a big compile. You may have problems compiling in resource constrained environments.

Running

• Notepad++ plug-in. Either run the installer, or change the compile location to compile the plug-in to the notepad++ plug-in directory for your systems
• Server: See install\readme.txt, and also, you need a copy of the full specification for the same version as the generated reference implementation code (see the downloads page for that version)
