Below are the specific steps taken during development: + +### 1. Base Class Integration +We inherited from the `TAPAdapter` base class in `tap_adapter_base.py`. This enforced a standard interface for fetching, transforming, and packaging data. + +### 2. OAuth2 with Token Rotation +Because John Deere access tokens are short-lived, we implemented a sophisticated authentication handler: +* **Registry Integration**: The adapter loads credentials and tokens from a local `farmers_registry.json` file. +* **401 Unauthorized Handling**: If an API call fails with a `401`, the adapter automatically triggers `refresh_token()`, updates the local registry with new tokens, and retries the original request seamlessly. + +### 3. Smart Data Discovery (`get_vendor_data`) +The adapter performs a two-stage discovery process: +* **Organization Fetching**: It first retrieves all organizations the authenticated user has access to. +* **Asset Probing**: For each organization, it attempts to fetch data from the latest `/equipment` endpoint. If that fails or returns no data, it falls back to the `/machines` endpoint to ensure no machinery is missed. + +### 4. SIRUP & BITE Transformation +To make the data "AI-ready," we implemented two transformation layers: +* **`transform_to_sirup`**: Normalizes various machine attributes (ID, Brand, Model, Serial Number) into a flat, predictable JSON structure. +* **`sirup_to_bite`**: Wraps the normalized data in a BITE (Basic Intelligence Terminal Entity) packet, complete with unique ULID headers, metadata, and cryptographic hashes for data integrity. + +--- + +## 📂 Project Structure + +| File | Purpose | +| :--- | :--- | +| `johndeere_adapter.py` | Main logic for JD API interaction and data transformation. | +| `tap_adapter_base.py` | The universal interface and factory for all TAP adapters. | +| `tap_vendors.yaml` | Configuration file where the JD adapter is registered with its API base URL and credentials. | +| `TESTING.md` | Comprehensive guide for running unit and integration tests. | + +--- + +## 🔧 Configuration + +To enable the adapter, ensure your `tap_vendors.yaml` includes the following entry: + +```yaml +- vendor_name: johndeere + adapter_class: tap_adapters.johndeere_adapter.JohnDeereAdapter + base_url: [https://sandboxapi.deere.com/platform](https://sandboxapi.deere.com/platform) + auth_method: oauth2 + credentials: + client_id: ${DEERE_CLIENT_ID} + client_secret: ${DEERE_CLIENT_SECRET} + + +🧪 Testing +For detailed instructions on verifying the implementation—including how to use the john-tap.py utility for initial authorization—please refer to the TESTING.md file. diff --git a/implementation/tap_adapters/John_deer_TESTING.md b/implementation/tap_adapters/John_deer_TESTING.md new file mode 100644 index 0000000..3116f12 --- /dev/null +++ b/implementation/tap_adapters/John_deer_TESTING.md @@ -0,0 +1,105 @@ +# John Deere Adapter: Testing & Integration Guide + +This document provides developers and maintainers with the steps required to verify the John Deere TAP adapter, ranging from mocked unit tests to real-world integration. + +--- + +## 1.
