• Import["file.jsonld"] imports a JSON-LD file, returning an RDFStore.
• Import["file.jsonld",elements] imports the specified elements.
• Export["file.jsonld",expr] exports an RDFStore to a JSON-LD file.

• General Import elements:
• "Elements" list of elements and options available in this file "Rules" full list of rules for each element and option "Options" list of rules for options, properties and settings
• Data representation elements:
• "Data" an RDFStore "RawData" nested associations and lists
• The "RawData" element is equivalent to the "RawJSON" format. The import result can be "compacted", "expanded", or "flattened" by specifying the "Profile" and "Context" import options.

• Import options:
• "Base" Automatic base IRI used to resolve relative IRIs "DocumentLoader" Automatic function used to import remote contexts "ExpandContext" None context used to initialize the active context during expansion "ProduceGeneralizedRDF" False whether to import a file that contains a blank node in a property position
• The value of "Base" is only used if the file does not specify a base IRI.
• "Base" can take the following values:
• Automatic the file name of the imported file None no base IRI "iri" or URL["iri"] an IRI
• An "ExpandContext" can be given to import a JSON file as an RDFStore.
• Additional Import options for the "RawData" element:
• "CompactArrays" True whether arrays of one element should be replaced with that element "Context" None context used for compaction "Profile" None how to represent data as JSONLD
• Specifying the "CompactArrays", "Context" and "Profile" options during "RawData" import has the same effect as specifying those options during Export.
• Export options:
• "CompactArrays" True whether arrays of one element should be replaced with that element "Context" None context used for compaction "ExpandContext" None context used to initialize the active context during expansion "Profile" "Compacted" how to represent data as JSONLD "UseNativeTypes" False whether number and Boolean literals should be expressed as JSON numbers and Booleans "UseRDFType" False whether rdf:type predicates should be exported as rdf:type or @type
• A "Context" is an association that specifies how short terms relate to IRIs, which datatypes values have and which classes IRIs belong to.
• A "Profile" specifies how data is represented as JSONLD. Possible value include:
• "Compacted" shorten IRIs to terms and compact IRIs, and values to numbers and string "Expanded" expand all terms and schort forms "Flattened" collect all properties of a node into a single JSON object and generate a label for each blank node
