RDF::Trine::Serializer::Notation3 - Notation 3 Serializer SYNOPSIS
use RDF::Trine::Serializer::Notation3; my $serializer = RDF::Trine::Serializer::Notation3->new(); DESCRIPTION
The RDF::Trine::Serializer::Notation3 class provides an API for serializing RDF graphs to the Notation 3 syntax. The output of this class is not optimised for human-readability; it's a data dump. The only minor concession it makes to human readers is that it will nicely indent formulae. I do have plans to port cwm's Notation 3 output to Perl, but this is likely to be distributed separately due to licensing concerns. Caveat scriptor: while RDF::Trine::Node::Formula understands quantification (@forAll, @forSome), RDF::Trine::Model does not. This means that @forAll and @forSome defined in the top-level graph are not-round-tripped between the Notation 3 parser and serialiser (the parser will give you warnings about this). @forAll and @forSome within formulae will work fine. METHODS
"new" Returns a new Notation 3 serializer object. "serialize_model_to_file ( $fh, $model )" Serializes the $model to Notation 3, printing the results to the supplied filehandle "<$fh">. "serialize_model_to_string ( $model )" Serializes the $model to Notation 3, returning the result as a string. "serialize_iterator_to_file ( $file, $iter )" Serializes the iterator to Notation 3, printing the results to the supplied filehandle "<$fh">. "serialize_iterator_to_string ( $iter )" Serializes the iterator to Notation 3, returning the result as a string. SEE ALSO

RDF::Trine::Serializer - RDF Serializer class VERSION
This document describes RDF::Trine::Serializer version 1.000 SYNOPSIS
use RDF::Trine::Serializer; DESCRIPTION
The RDF::Trine::Serializer class provides an API for serializing RDF graphs (via both model objects and graph iterators) to strings and files. METHODS
"serializer_names" Returns a list of valid serializer names for use as arguments to the serializer constructor. "new ( $serializer_name, %options )" Returns a new RDF::Trine::Serializer object for the serializer with the specified name (e.g. "rdfxml" or "turtle"). If no serializer with the specified name is found, throws a RDF::Trine::Error::SerializationError exception. The valid key-values used in %options are specific to a particular serializer implementation. For serializers that support namespace declarations (to allow more concise serialization), use "namespaces => \%namespaces" in %options, where the keys of %namespaces are namespace names and the values are (partial) URIs. For serializers that support base URI declarations, use "base_uri => $base_uri" . "negotiate ( request_headers => $request_headers, %options )" Returns a two-element list containing an appropriate media type and RDF::Trine::Serializer object as decided by HTTP::Negotiate. If the 'request_headers' key-value is supplied, the $request_headers is passed to "HTTP::Negotiate::choose". The option 'restrict', set to a list of serializer names, can be used to limit the serializers to choose from. Finally, an "<'extends' "> option can be set to a hashref that contains MIME-types as keys and a custom variant as value. This will enable the user to use this negotiator to return a type that isn't supported by any serializers. The subsequent code will have to find out how to return a representation. The rest of %options is passed through to the serializer constructor. "media_types" Returns a list of media types appropriate for the format of the serializer. "serialize_model_to_file ( $fh, $model )" Serializes the $model, printing the results to the supplied filehandle "<$fh">. "serialize_model_to_string ( $model )" Serializes the $model, returning the result as a string. "serialize_iterator_to_file ( $file, $iterator )" Serializes the statement objects produced by $iterator, printing the results to the supplied filehandle "<$fh">. Note that some serializers may not support the use of this method, or may require the full materialization of the iterator in order to serialize it. If materialization is required, available memeory may constrain the iterators that can be serialized. "serialize_iterator_to_string ( $iterator )" Serializes the statement objects produced by $iterator, returning the result as a string. Note that the same constraints apply to this method as to "serialize_iterator_to_file". 1; __END__ BUGS
