# FHIR Pattern Languages

> Reusable guidance for healthcare interoperability — three pattern languages covering FHIR implementation architecture, FHIR authoring, and IG authoring.

This is an AI agent discovery file for the **FHIR Pattern Languages** collection at [https://fhirpatterns.net/](https://fhirpatterns.net/).

## What This Site Contains

This site hosts three independent, navigable pattern languages. Each pattern documents a recurring problem, the forces that shape its solution, the solution itself, its consequences, and related patterns. Patterns are interlinked into networks that support decision-making across the FHIR lifecycle.

## Pattern Languages

### FHIR Implementation Patterns

Distributed FHIR patterns for interoperability, privacy, security, imaging, and integration.

- **URL**: https://fhirpatterns.net/fhir-implementation-patterns/
- **Agent instructions**: https://fhirpatterns.net/fhir-implementation-patterns/agents.md
- **Content index** (llms.txt): https://fhirpatterns.net/fhir-implementation-patterns/llms.txt
- **Full content** (all patterns): https://fhirpatterns.net/fhir-implementation-patterns/llms-full.txt

### FHIR Authoring Pattern Language

Patterns for building FHIR R4 Implementation Guides and terminology artifacts with fast feedback using HL7 tooling.

- **URL**: https://fhirpatterns.net/fhir-authoring-patterns/
- **Agent instructions**: https://fhirpatterns.net/fhir-authoring-patterns/agents.md
- **Content index** (llms.txt): https://fhirpatterns.net/fhir-authoring-patterns/llms.txt
- **Full content** (all patterns): https://fhirpatterns.net/fhir-authoring-patterns/llms-full.txt

### IG Authoring Pattern Language

Patterns for authoring HL7 FHIR Implementation Guides with disciplined repository layout, naming, ADR governance, FSH usage, reuse, and robust CI.

- **URL**: https://fhirpatterns.net/ig-authoring-patterns/
- **Agent instructions**: https://fhirpatterns.net/ig-authoring-patterns/agents.md
- **Content index** (llms.txt): https://fhirpatterns.net/ig-authoring-patterns/llms.txt
- **Full content** (all patterns): https://fhirpatterns.net/ig-authoring-patterns/llms-full.txt

## Usage Guidance

- For a specific pattern language, navigate to its `agents.md` for targeted context
- Use `llms.txt` for a concise index of pages with descriptions
- Use `llms-full.txt` for the complete text of all patterns in one document
- Each pattern page follows a consistent structure: problem, context, forces, solution, consequences, related patterns
