Structured data
Schema.org @graph
Also: JSON LD @graph, connected schema, structured data graph
A typical business homepage @graph declares the Organization (or the right LocalBusiness subtype for a local business) with an @id ending in #organization, a WebSite, the people who run it with worksFor pointing back, and each Service with provider pointing back.
Several disconnected JSON LD blocks, each repeating the business under a different identity, are a common mistake. One block with one @graph and stable @id values is easier to maintain and harder to contradict. Markup must describe what is visible on the page.
