Architecture

InkGen’s modular architecture enables efficient FHIR code generation while maintaining extensibility for new languages and features.

Directory Overview

  • overview.md - High-level system design and data flow
  • concepts.md - Core concepts: IR, genealogy, profiles, extensions
  • ir-design.md - Internal Representation (IR) structure and evolution
  • type-system.md - Type mapping and resolution across languages

Key Principles

  1. Separation of Concerns: FHIR parsing, IR construction, and code generation are independent
  2. Extensibility: Add new language backends without modifying core
  3. Performance: Caching, parallel processing, and lazy evaluation where possible
  4. Correctness: Type safety and constraint validation throughout the pipeline

See Architecture Decision Records for design rationale on major decisions.
