カタログのモデルに、あなたのシステムで要る属性を足すときに使います。モデルを選んで属性を入力すると、次の 2 つのファイルができます。
- @context: カタログの
@contextを URL で読み込み、あなたの属性だけを定義します。カタログの属性は IRI が変わりません。拡張するのプロファイルと同じ書き方です。 - JSON Schema: カタログの属性とあなたの属性で検証します。
名前空間には、あなたが管理するドメインの URL を使ってください。多くのシステムで役に立つ属性なら、カタログへの提案をお願いします（下のリンクから）。入力した内容はこのページの中だけで使われ、どこにも送られません。ただし、提案フォームへのリンクを開くと、入力した属性名と説明が GitHub に送られます（フォームに入力済みの状態で開くため）。
あなたの属性
あなたの @context

}JSON Schema（カタログの属性 + あなたの属性）
カタログのスキーマは閉じている（additionalProperties: false）ため、参照だけでは属性を足せません。これは https://datamodels.jp/schema/transportation/RoadRestriction/v1.0.0.json をもとに作ったもので、新しいバージョンに移るときは作り直してください。$id はあなたの URL に書き換えてください。
