Parameters:

activeProperty - The Active Property

value - The value to compact

Returns:

The compacted value

_iriCompactionStep5point4

public static String _iriCompactionStep5point4(String iri,
                                               Object value,
                                               String compactIRI,

getPrefixes

public Map<String,String> getPrefixes(boolean onlyCommonPrefixes)

Return a map of potential RDF prefixes based on the JSON-LD Term Definitions in this context.

No guarantees of the prefixes are given, beyond that it will not contain ":".

Parameters:

onlyCommonPrefixes - If true, the result will not include "not so useful" prefixes, such as "term1": "http://example.com/term1", e.g. all IRIs will end with "/" or "#". If false, all potential prefixes are returned.

Returns:

A map from prefix string to IRI string

public Context clone()

Overrides:

clone in class HashMap<String,Object>

getInverse

public Map<String,Object> getInverse()

Inverse Context Creation http://json-ld.org/spec/latest/json-ld-api/#inverse-context-creation Generates an inverse context for use in the compaction algorithm, if not already generated for the given active context.

Returns:

the inverse context.

getContainer

public String getContainer(String property)

Retrieve container mapping.

Parameters:

property - The Property to get a container mapping for.

Returns:

The container mapping if any, else null

isReverseProperty

public Boolean isReverseProperty(String property)

getTypeMapping

public String getTypeMapping(String property)

getLanguageMapping

public String getLanguageMapping(String property)

expandValue

public Object expandValue(String activeProperty,
                          Object value)
                   throws JsonLdError

Throws:

JsonLdError
