Building a "Knowledge Graph" for E-commerce: Using JSON-LD Schema to Bridge the Identity Gap

The circular sameAs reference pattern is clever for entity disambiguation. One thing worth considering: if you are syncing schema across Shopify + Amazon + LinkedIn, you might run into stale sameAs links when one platform changes its URL structure. We built a scheduled validator that checks each sameAs URL returns 200 — caught three broken links in the first month that would have silently degraded our Knowledge Panel.
