Linked Data
Linked Data ‘is structured data which is interlinked with other data so it becomes more useful through semantic queries.’
What is now generally discussed as linked data used to be referred to as Semantic Web.
See JSON-LD, Linked Data terminology and technologies, Interoperability, IPLD allows us to treat all hash-linked data structures as subsets of a unified information space.
See Grading scheme for open data, formats.
