3a. Project Scope

FHIR Shorthand is a specification of a domain-specific language (DSL) to allow Implementation Guide authors to define conformance resources (e.g., StructureDefinitions, ValueSets, etc.) and general instances (e.g., examples). This project will define the syntax of FHIR Shorthand, and develop a reference implementation of an importer/exporter/compiler ("Sushi") that creates FHIR content ready for the FHIR IG Publisher or other consumers of Conformance Resources. Project will also explore importing StructureDefinitions to FSH.

3b. Project Need

To better support complex clinical modeling/profiling projects and effectively integrate across projects.

Explanation:
To grow, the FHIR community needs scalable, user-friendly tools for IG creation and maintenance. Currently, IG projects are difficult and slow, and the results inconsistent. As a user-facing format, StructureDefinitions (SDs) are complex and unwieldy. While available tools (Forge, Trifolia-on-FHIR, Excel spreadsheets) improve this situation, there are still shortcomings:
a. Although the current tools provide a friendlier interface, the tools are not particularly agile when it comes to refactoring.
b. Source code control system (SCCS) features such as differentials and merging changes are not well supported. Excel files cannot be effectively diff’ed, and the other tools can be managed in SCCS only as SDs.

To address these limitations, we propose a domain specific language (DSL) designed for the job of defining profiles, extensions, invariants, value sets, examples, search parameters, etc. FHIR Shorthand (FSH) will be designed to work optimally with SCCS, with meaningful differentials, support for merging and conflict resolution, and refactoring through global search/replace operations. These features will permit FSH to scale in ways that visual editors and spreadsheets cannot.
