Why a Textual Language?

• Grammar is designed to concisely express exactly what you need to

• Complex projects are much easier when you use a language

• 10x faster & more agile

Agile Profile Development in CIMPL

• Write once, use many times

• Global search & replace (your BFF )

• Source code control (with meaningful diffs)

• Distributed, collaborative development

• All major FHIR versions at once

CIMPL Sample

Generates a StructureDefinition with 2760 lines of JSON

Use any text editor (but try our Visual Studio Code plug-in)

CIMPL Sample Object-oriented paradigm

Parent class from CIMPL Class Library

Distributed, Collaborative Development

Advanced Features

CIMPL is Object-Oriented

• Create classes by subclassing, extending, constraining

• Base class library “Objective FHIR”

• Objective FHIR ("OBF") is an object-oriented abstraction of FHIR

• OBF provides a consistent view of DSTU 2, STU 3 and R4 and makes

resulting profiles more interoperable

• Example: Consistent modeling of body locations

Reusability Superior Interoperability

• Everything in CIMPL is reusable

• Anything can be subclassed

Multiple FHIR Versions: Semantic Compatibility

DSTU 2 (2015)

STU 3 (2017)

R4 (2019)

• Argonaut Data Query

• Apple Health Records

• Epic

• Cerner

• mCODE

• Argonauts Provider Directory

• Argonauts Scheduling

• US Core

• CMS Blue Button 2.0 IG

• DaVinci Project
