Most sites ship structured data as scattered snippets — one Article block here, one Organization block there. Schema implementation as @id graph connects every node by stable URIs: Person, Organization, WebSite, Article, Product, FAQ, BreadcrumbList. Deployment is wired into CI so validation fails fast, before reaching production.

Stable @id URIs for Person, Organization, WebSite, Brand, Product. Cross-page references via @id, not inlined duplication.
Article, BlogPosting, FAQPage, HowTo, Product, Offer, Service, Event, BreadcrumbList — mapped to your content types with consistent property usage.
Schema.org validator, Google Rich Results Test and JSON-LD lint wired into CI. Pull requests fail when invalid markup ships.
Style guide, ownership model, change-control for new schema types and properties. Versioning of the graph in a documented source-of-truth.
