JSON-LD 形式で schema.org ボキャブラリをリクエストする場合 (これは、次のリクエスト ヘッダーを介して実行できます):
Accept: application/ld+json, application/json;q=0.9, application/javascript;q=0.5, text/javascript;q=0.5, text/plain;q=0.2, */*;q=0.1
応答文書 (下部に含まれている部分を切り取ったもの) は非常に小さく、一見すると不完全に見えます。いくつかの属性のみがリストされており、完全な階層で示されているようなタイプはないようです。http://schema.org/CreativeWorkという 1 つのタイプを見ても、ドキュメントには表示されない多くの属性があります (例:キーワード)。すべての Thing の一部である属性nameでさえ、結果には表示されません。
schema.org で言及されているすべての属性がこのドキュメントに含まれていないのはなぜですか?
