## Overview

The EA Modeler is a canvas-based tool for building and maintaining your organization's enterprise architecture. Models are created using ArchiMate 4 notation and are intended to be implementable — not just decorative diagrams. They connect directly to the products, technology, and operations managed elsewhere in the platform.

## Key Concepts

- **ArchiMate 4** — The open standard notation used for all models. It supports three layers: Business (processes, actors, roles), Application (software, interfaces, services), and Technology (infrastructure, platforms, networks).
- **Views and Viewpoints** — A viewpoint defines which elements and relationships are relevant for a particular audience. A view is a specific diagram built from that viewpoint.
- **Reference Models** — Prebuilt architecture patterns (e.g., cloud-native application, integration hub) that can be adapted and incorporated into your own models.
- **Value Streams** — End-to-end sequences of activities that deliver value to a customer or stakeholder. Modelled in the business layer and traceable to the products and capabilities that enable them.

## What You Can Do

- Create and edit architecture views across business, application, and technology layers
- Apply standard ArchiMate viewpoints or define custom ones for your audience
- Start from reference models and tailor them to your organization
- Map value streams to the products and capabilities that support them
- Use the AI coworker to generate a draft architecture view from a description
