如何使用schema.org在同一页面引用已定义的LocalBusiness条目？

Absolutely! You can totally eliminate that redundant LocalBusiness definition by using JSON-LD's @id property to create a single shared entry for your yoga studio, then referencing it in both Event listings. This keeps your code DRY (Don't Repeat Yourself) and ensures consistency across all your events.

How It Works #

1. Define your business once: Create a single LocalBusiness object with a unique @id (we’ll use a fragment like #hello-yoga-studio for simplicity—this just needs to be unique on your page).
2. Reference it in each event: Instead of retyping the entire business object under performer, just point to the @id you created. Schema parsers will automatically link the event to your shared business entry.

Quick Tips #

• We wrapped everything in an @graph array to keep all schema entities in one script—this makes it easier for search engines and parsers to recognize the relationships between your business and events.
• The @id can be any unique value, but using a fragment identifier (like #hello-yoga-studio) is a simple, standard approach for page-internal references.
• Now, if you need to update your business details (like email or description), you only have to edit one spot instead of two—win-win!
