-# data-contracts
+# backend-data-contracts
 
-This repository is the single source of truth for all Protocol Buffer (Protobuf) schema definitions used across the Rail Ingress and Processing microservices.
+This repository is the single source of truth for all schema definitions used across the Owlboard backend communication and storage services.  Language specific types are generated here and published to the Gitea package repository linked to the repo.
 
-## Purpose
+## Directory Structure
 
-The Protobuf files defined here serve as the immutable data contract for:
-1.  **Message Queue Payloads:** Defining messages pushed to the Artemis queue (Go Process Service consumption).
-2.  **Database Schemas:** Defining the expected structure of documents in MongoDB (Go Process and TypeScript API service consumption).
-3.  **Cross-Service Communication:** Ensuring type-safe data exchange between all polyglot services (Go, TypeScript).
+| Path | Description |
+| :--- | :--- |
+| `schemas` | JSON Schema files organised into clear subfolders |
+| `scripts` | Workflow Scripts |
 
-## Directory Structure and Artifacts
+## Code Generation and Publishing Workflow
 
-| Path | Description | Contents |
-| :--- | :--- | :--- |
-| `protos/rail/v1/` | **Source Code.** Contains all source `.proto` files. **Only these files reside on the `main` branch.** | `.proto` files |
-| `ts/` | **Generated TypeScript/JavaScript code.** Used as the root for the NPM package publish. **Not committed to Git.** | `package.json`, generated `.js`, `.d.ts` |
-| `go.mod` | Defines the Go Module path: `git.fjla.uk/owlboard/backend-data-contracts`. | Go Module definition |
+The generation and release process is automated via Gitea Actions. It is triggered whenever a new **SemVer tag** (e.g., `v1.0.0`) is pushed to this repository.
 
-## Code Generation and Publishing Workflow (Gitea Action)
+## To Consume the Contracts
 
-The generation process is automated via a Gitea Action (`.gitea/workflows/generate_contracts.yml`), which runs when a change is pushed to a source `.proto` file.
+### 1. Go Services
+Since the package is hosted in the Gitea Package Registry, you must configure your environment to use the Gitea instance as a proxy.
 
-The action performs the following steps:
-1.  Generates all Go and TypeScript/JavaScript artifacts.
-2.  **Go Artifacts:** Commits the generated `*.pb.go` files to a **new Git tag** (e.g., `v1.0.1`), ensuring the `main` branch remains clean.
-3.  **TypeScript Artifacts:** Packages the generated files and publishes the corresponding version (e.g., `1.0.1`) to the internal NPM registry.
+**Setup:**
+```bash
+# Set the proxy to check our Gitea instance first
+go env -w GOPROXY="https://git.fjla.uk/api/packages/OwlBoard/go,https://proxy.golang.org,direct"
 
-### To Consume the Contract:
+# Trust our internal domain and skip the public Google checksum database
+go env -w GONOSUMDB="git.fjla.uk"
+```
 
-| Language | Artifact | Consumption Method |
-| :--- | :--- | :--- |
-| **Go** | Source Code (`*.pb.go`) | **Requires a Git Tag.** Update your service's `go.mod` file to reference the desired tag: `git.fjla.uk/owlboard/backend-data-contracts v1.0.1`. |
-| **TypeScript** | NPM Package | Update the version in your `package.json` file and install: `"@owlboard/contracts": "1.0.1"`. |
+The, you can simply run go get, as usual.
+
+#### Container Usage
+```bash
+ARG GOPROXY=https://git.fjla.uk/api/packages/OwlBoard/go,https://proxy.golang.org,direct
+ARG GONOSUMDB=git.fjla.uk
+ENV GOPROXY=$GOPROXY
+ENV GONOSUMDB=$GONOSUMDB
+```
+
+### 2. Typescript Services
+You will need to configure .npmrc in your projects root directory to point to the correct repo:
+
+```bash
+@owlboard:registry=https://git.fjla.uk/api/packages/OwlBoard/npm/
+```
+
+Then you can install as usual:
+
+```bash
+npm install @owlboard/backend-data-contracts@0.1.0
+```
