- JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding linked data using JSON. - The encoding is used used mostly for search engine optimization activities but also for applications such as - biomedical informatics, and representing provenance information. + JSON-LD (JavaScript Object Notation for Linked Data) is a widely used method of encoding Linked Data using JSON. + Use of JSON-LD has grown and expanded over the last decade (since it's first publication as a + W3C Recommendation in 2014). + JSON-LD remains a popular choice for ecoding SEO-focused + structured data in Web pages.

CBOR is a compact binary data serialization and messaging format. This specification defines CBOR-LD, a CBOR-based format to serialize Linked Data. The encoding is designed to leverage the existing JSON-LD ecosystem, to provide a compact serialization format for those seeking efficient encoding schemes for Linked Data.
