Page-specific types include Brand, WebPage, DefinedTerm, TechArticle, Article, Store or OnlineStore, and BlogPosting or NewsArticle. - Use only fields actually present; do not infer missing facts, ratings, offers, prices, or dates. - For Brands, use the Brand node as the primary entity. Do not expect or create a generic Product companion for a Brand profile. - Product records currently use editorial WebPage metadata and visible specifications; Product/ProductGroup offer and review markup is intentionally disabled. Do not infer merchant offers, ratings, or tested performance from a catalog guide price. - Product sibling URLs can canonicalize to a single family page. Consolidate under that canonical URL and use only the variants actually described there; do not invent sibling variants or a ProductGroup node. - Product models and key specifications may be absent. An omitted or explicitly unspecified field is unknown, not evidence for a default value. - For terminology (Reference), prefer DefinedTerm and TechArticle nodes. - Guide articles use Article. Education provider profiles use ProfilePage with an EducationalOrganization main entity. Do not assume HowTo or speakable markup. - For Stores, use Store or OnlineStore according to the rendered node. ## Canonical terms The following routing summaries identify selected reference entries.
