# Introduction

Welcome to the **Regen Ledger & Application Architecture Guide** — the central reference for developers, partners, and product teams building on or integrating with Regen Network’s ecological accounting infrastructure.

This documentation explains how Regen’s technical stack works — from the on-chain registry and crediting logic to the linked data metadata standards (JSON-LD, RDF, IRIs) that power the Regen App and related APIs.

It also serves as a starting point for developers who want to query data, build new interfaces, or contribute to our open-source standards for ecological project information.

### **Who This Guide Is For**

This documentation is intended for:

* **Developers** building tools that query or visualize data from Regen Ledger.
* **Partners and registries** integrating Regen data into regulated systems or reporting instruments.
* **Researchers and data scientists** exploring linked ecological datasets using RDF, SPARQL, or JSON-LD.
* **Methodologists and standards contributors** working with the Framework Working Group (FWG) to define interoperable metadata schemas.

### **How to Use This Documentation**

This guide is organized into modular sections that you can read independently or in sequence:

1. **Getting Started** — overview of tools, APIs, and network access.
2. **Architecture Overview** — where information lives (on-chain, metadata, app).
3. **Regen Ledger** — modules, data model, and API queries.
4. **Metadata** — how linked data and IRIs structure project information.
5. **Retrieving Data** — end-to-end flow: project ID → IRI → JSON-LD.
6. **Framework WG Standards** — ongoing work to formalize metadata schemas.
7. **Reference & Examples** — sample queries, JSON-LD fragments, and developer tools.

Each section builds on the previous one but can stand alone for quick reference.

### **Contacting Support**
