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.
