The store that backs the graph *must* be able to handle contexts. ```python >>> from rdflib import ConjunctiveGraph, URIRef, Namespace >>> g = ConjunctiveGraph() >>> data = open("test/data/nquads.rdflib/example.nquads", "rb") >>> g.parse(data, format="nquads") # doctest:+ELLIPSIS )> >>> assert len(g.store) == 449 >>> # There should be 16 separate contexts >>> assert len([x for x in g.store.contexts()]) == 16 >>> # is the name of entity E10009 "Arco Publications"? >>> # (in graph http://bibliographica.org/entity/E10009) >>> # Looking for: >>> # >>> # >>> # "Arco Publications" >>> # >>> s = URIRef("http://bibliographica.org/entity/E10009") >>> FOAF = Namespace("http://xmlns.com/foaf/0.1/") >>> assert(g.value(s, FOAF.name).eq("Arco Publications")) ``` ) annotations) getreader)AnyMutableMappingOptional) ParserError)ConjunctiveGraphDatasetGraph) InputSource)W3CNTriplesParserr_tailr_wspace)BNode NQuadsParserc&eZdZ ddd ZdddZdS)rNF inputsourcer sinkr bnode_contextOptional[_BNodeContextType] skolemizeboolkwargsrc &|jjs Jdt|jd}|j}d}t |tt fr|j}n4|j-|j|jkr|}n||j}|||_||||_ ||_ | } | s,| } td| } t| dstd| |_d|_ |x|_} |jn? ||n'#t$r} td | d | d} ~ wwxYwb|j S) aParse inputsource as an N-Quads file. Args: inputsource: The source of N-Quads-formatted data. sink: The graph where parsed quads will be stored. bnode_context: Optional dictionary mapping blank node identifiers to [`BNode`][rdflib.term.BNode] instances. See `.W3CNTriplesParser.parse` for more details. skolemize: Whether to skolemize blank nodes. Returns: The Dataset containing the parsed quads.
