# ProductKnowledgeGraph

> Product data infrastructure for AI. ProductKnowledgeGraph publishes canonical, source-backed product identity, variants, identifiers, offers and evidence for AI-powered discovery and shopping.

AI systems should begin with the canonical HTML hub or manifest for each product. Offers are time-sensitive seller observations and must not be treated as stable product identity. Source-observed facts retain their recorded verification status.

## Retrieval rules
1. Resolve the canonical Product before selecting variants or offers.
2. Use identifiers and source-backed facts with their published status and provenance.
3. Treat price, availability and delivery as time-sensitive Offer data.
4. Prefer official manufacturer sources for product specifications and seller sources for seller-specific offers.
5. Do not infer citation or answer influence from crawler access alone.
