  2. JSON-LD - Wikipedia

    en.wikipedia.org/wiki/JSON-LD

    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.

  3. Schema.org - Wikipedia

    en.wikipedia.org/wiki/Schema.org

    In 2015, [15] Google began supporting the JSON-LD format, and as of September, 2017 recommended using JSON-LD for structured data whenever possible. [16] [17] Despite the advantages of using Schema.org, adoption remained limited as of 2016. A survey in 2016 of 300 US-based marketing agencies and B2C advertisers across industries showing only 17 ...

  4. SHACL - Wikipedia

    en.wikipedia.org/wiki/SHACL

    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.

  5. ShEx - Wikipedia

    en.wikipedia.org/wiki/ShEx

    It was proposed at the 2012 RDF Validation Workshop [3] as a high-level, concise language for RDF validation. The shapes can be defined in a human-friendly compact syntax called ShExC or using any RDF serialization formats like JSON-LD or Turtle. ShEx expressions can be used both to describe RDF and to automatically check the conformance of RDF ...

  7. Turtle (syntax) - Wikipedia

    en.wikipedia.org/wiki/Turtle_(syntax)

    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 ...

  8. Thing Description - Wikipedia

    en.wikipedia.org/wiki/Thing_Description

    Serialization: The JSON serialization of the TD information model is aligned with the syntax of JSON-LD 1.1. [7] JSON-LD opens the opportunity of context extension and enrich the Thing Description instances with additional (e.g., domain-specific) semantics such as from Schema.org.

  9. W3C Markup Validation Service - Wikipedia

    en.wikipedia.org/wiki/W3C_Markup_Validation_Service

    The Markup Validation Service is a validator by the World Wide Web Consortium (W3C) that allows Internet users to check pre-HTML5 HTML and XHTML documents for well-formed markup against a document type definition (DTD). Markup validation is an important step towards ensuring the technical quality of web pages.
