Question
Which title, image, type, and URL should a sharing consumer preview?
Nodes
WebPage; Preview image; Title; Object type; URL
Relationship sketch
- page → preview metadata
- preview → image asset
Evidence inputs
Actual rendered head metadata and observed sharing previews under stated conditions.
Implementation
Maintain Open Graph metadata alongside ordinary metadata and check consumer-specific output. Treat this as a preview representation, not as your semantic entity registry or evidence store.
Acceptance checks
- Preview URL and image match the intended page
- Metadata is not copied with wrong titles across routes
- Observed previews are recorded separately from configured intent
Do not infer
Open Graph, Google Knowledge Graph, and GraphRAG are three different things.
Publication boundary
Public page metadata.
Source basis
