| # Understanding Integrator Development Kit (IDK) metadata |
| |
| The manifest of the Fuchsia IDK is a JSON file that is described using |
| a [JSON schema](https://json-schema.org/latest/json-schema-core.html). |
| The goal of having a metadata based description of the IDK is to allow |
| automated processing of the IDK to integrate it into build environments |
| and SDKs usable by developers. |
| |
| It is expected that the contents and structure of the IDK will change over time |
| so care should be taken when interpreting the metadata during any transformations. |
| The source of truth for the structure of the metadata is always the files contains in |
| the `meta/schemas` directory of the IDK. |
| |
| The source for the schema is found in [`//build/sdk/meta`](/build/sdk/meta). |
| |
| ## Manifest structure |
| |
| The [manifest](/build/sdk/meta/manifest.json) has the following required properties: |
| |
| Property | Description |
| :----------------|:-------------: |
| | arch | Architecture targeted for this SDK. There is a host architecture and a list of target device architectures. | |
| | id | Build id of the SDK. | |
| | parts | The array of elements in the SDK. Each part has a type, which is defined in `meta/schemas/<type>.json` | |
| | schema_version | The version of the schema for the metadata. This value should be verified when using an automated integration process to make sure the metadata is being interpreted correctly. | |
| |
| |
