Class Definitions

The following are class definitions in the jsonld namespace:

Context	Context § Defines term definitions and other aspects of a JSON-LD Context. A context definition MUST be a map whose keys MUST be either terms, compact IRIs, IRIs, or one of the keywords @base, @import, @language, @propagate, @protected, @type, @version, or @vocab. You can read more about this feature in the JSON-LD Syntax Specification.
PrefixDefinition	Prefix Definition § A string (simple term definition), expanding to an IRI. You can read more about this feature in the JSON-LD Syntax Specification.
TermDefinition	Term Definition § A term definition is an entry in a context, where the key defines a term which may be used within a dictionary as a key, type, or elsewhere that a string is interpreted as a vocabulary item. Its value is an expanded term definition. An expanded term definition MUST be a map composed of zero or more keys from @id, @reverse, @type, @language, @container, @context, @prefix, @propagate, or @protected. An expanded term definition SHOULD NOT contain any other keys. You can read more about this feature in the JSON-LD Syntax Specification.

Property Definitions

The following are property definitions in the jsonld namespace:

base	base § If the context definition has an @base key, its value MUST be an IRI reference, or null. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:anyUri schema:domainIncludes jsonld:Context
container	container § The associated @container value in an expanded term definition. If the expanded term definition contains the @container keyword, its value MUST be either @list, @set, @language, @index, @id, @graph, @type, or be null or an array containing exactly any one of those keywords, or a combination of @set and any of @index, @id, @graph, @type, @language in any order. @container may also be an array containing @graph along with either @id or @index and also optionally including @set. If the value is @language, when the term is used outside of the @context, the associated value MUST be a language map. If the value is @index, when the term is used outside of the @context, the associated value MUST be an index map. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes jsonld:ContainerType schema:domainIncludes jsonld:TermDefinition
context	context § As an IRI, this link relation is used to associate a JSON-LD context with a JSON document so that it can be interpreted as JSON-LD. In an HTTP request header, specifies the location of a context to use for compaction. As a Context, defines an inline context definition. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes jsonld:Context, xsd:anyUri
definition	definition § Term definition(s) associated with this context. schema:rangeIncludes jsonld:TermDefinition, jsonld:PrefixDefinition schema:domainIncludes jsonld:Context
direction	direction § If the context definition has an @direction key, its value MUST be one of "ltr" or "rtl", or be null. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:string schema:domainIncludes jsonld:Context, jsonld:TermDefinition
id	id § The @id mapping of a term definition. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:anyUri schema:domainIncludes jsonld:TermDefinition, jsonld:PrefixDefinition
import	import § If the context definition contains the @import keyword, its value MUST be an IRI reference. When used as a reference from an @import, the referenced context definition MUST NOT include an @import key, itself. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:anyUri schema:domainIncludes jsonld:Context
language	language § The default language is set in the context using the @language key whose value MUST be a string representing a BCP47 language code or null. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:string schema:domainIncludes jsonld:Context, jsonld:TermDefinition
nest	nest § If the expanded term definition contains the @nest keyword, its value MUST be either @nest, or a term which expands to @nest. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:string schema:domainIncludes jsonld:TermDefinition
prefix	prefix § With the value true, allows this term to be used to construct a compact IRI when compacting. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:boolean schema:domainIncludes jsonld:TermDefinition
propagate	propagate § If the context definition contains the @propagate keyword, its value MUST be true or false. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:boolean schema:domainIncludes jsonld:Context, jsonld:TermDefinition
protected	protected § If the context definition contains the @protected keyword, its value MUST be true or false. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:boolean schema:domainIncludes jsonld:Context, jsonld:TermDefinition
reverse	reverse § The @reverse mapping of an expanded term definition. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:anyUri schema:domainIncludes jsonld:TermDefinition
term	term § The term associated with a term definition. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:string schema:domainIncludes jsonld:TermDefinition, jsonld:PrefixDefinition
type	type § If the context definition contains the @type keyword, its value MUST be a map with only the entry @container set to @set, and optionally an entry @protected. If the expanded term definition contains the @type keyword, its value MUST be an IRI reference, a term, null, or one of the keywords @id, @json, @none, or @vocab. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:anyUri, xsd:string schema:domainIncludes jsonld:Context, jsonld:TermDefinition
version	version § The processing mode defines how a JSON-LD document is processed. By default, all documents are assumed to be conformant with JSON-LD 1.1`. By defining a different version via explicit API option, other processing modes can be accessed. This specification defines extensions for the json-ld-1.1 processing mode. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:decimal schema:domainIncludes jsonld:Context
vocab	vocab § Used to expand properties and values in @type with a common prefix IRI. You can read more about this feature in the JSON-LD Syntax Specification. schema:rangeIncludes xsd:anyUri schema:domainIncludes jsonld:Context

Instance Definitions
