sameAs
In data science, sameAs or exactMatch is a method of indicating that the subject of, or entity represented by, two resources is considered to be one and the same thing. It is a key part of the Semantic Web.
Uses
The concept of sameAs exists in a number of different schemas and systems:
- JSON-LD[1]
- OWL -
owl:sameAs[2] - schema.org[3]
- SKOS -
skos:exactMatch[4] - Wikidata - Property:P2888 "exact match", with the alias "sameas"[5]
The owl:sameAs predicate has been described as "an essential ingredient of the Semantic Web architecture".[2]
Recognition
Google recognises sameAs relationships expressed via schema.org or JSON-LD, used by individuals or organisations, and uses them to populate the Google Knowledge panel in search results.[1]
