JSON-LD is designed around the concept of a "context" to provide additional mappings from JSON to an RDF model. The context links object properties in a JSON document to concepts in an ontology. In order to map the JSON-LD syntax to RDF, JSON-LD allows values to be coerced to a specified type or to be tagged with a language.
The CP/LD format defines a flexible, extensible, machine readable format that links HTML5 documents with content to JSON-LD graphs for the data and semantics. [1]The Linked Document part of the standard outlines the minimal characteristics of documents, whereas the Content Profile part describes how to extend and refine rules for specific use cases.
SensorThings API is designed specifically for resource-constrained IoT devices and the Web developer community. It follows REST principles, the JSON encoding, and the OASIS OData protocol and URL conventions.

A SHACL validation engine takes as input a graph to be validated (called data graph) and a graph containing SHACL shapes declarations (called shapes graph) and produces a validation report, also expressed as a graph. All these graphs can be represented in any Resource Description Framework (RDF) serialization formats including JSON-LD or Turtle.
Free and open-source software portal; Vega and Vega-Lite are visualization tools implementing a grammar of graphics, similar to ggplot2.The Vega and Vega-Lite grammars extend Leland Wilkinson's Grammar of Graphics [2] by adding a novel grammar of interactivity to assist in the exploration of complex datasets.
It is a common data format for storing RDF data, along with N-Triples, JSON-LD and RDF/XML. RDF represents information using semantic triples, which comprise a subject, predicate, and object. Each item in the triple is expressed as a Web URI. Turtle provides a way to group three URIs to make a triple, and provides ways to abbreviate such ...
The NGSI-LD meta-model [15] formally defines these foundational concepts (Entities, Relationships, Properties) on the basis of RDF/RDFS/OWL, and partially on the basis of JSON-LD. An entity is the informational representative of something (a referent) that is supposed to exist in the real world, outside of the computational platform using NGSI ...
