How to handle structured data for multilingual content in Schema markup?

When handling structured data for multilingual content, Schema markup must ensure that different language versions are accurately recognized by search engines through language attributes and association mechanisms. This is typically achieved by combining language tags, multilingual attributes, and page associations. In practice, the following methods can be used: - Language identification: Use the `@language` attribute to specify the corresponding language code for Schema data in each language version (e.g., `"@language": "en"` or `"@language": "zh-CN"`) to clarify the content language. - Multilingual attributes: For core fields such as name and description, provide different language versions using `alternateName` or a custom multilingual array (e.g., `"name": {"en": "Apple", "zh-CN": "苹果"}`). - Page association: If multilingual content corresponds to different URLs, associate language-specific pages using the `sameAs` attribute or `<link rel="alternate" hreflang="x"` tags to help search engines understand the content correspondence. It is recommended to use Google's Structured Data Testing Tool to verify the completeness and correctness of each language version after markup, ensuring that multilingual Schema data conforms to search engine interpretation logic.
