Overview

RDFa format specification.

Examples:

Obtaining an Notation3 format class

RDF::Format.for(:n3)            #=> RDF::N3::Format
RDF::Format.for("etc/foaf.n3")
RDF::Format.for(file_name:      "etc/foaf.n3")
RDF::Format.for(file_extension: "n3")
RDF::Format.for(content_type:   "text/n3")

Obtaining serialization format MIME types

RDF::Format.content_types      #=> {"text/n3")" => [RDF::N3::Format]}

Obtaining serialization format file extension mappings

RDF::Format.file_extensions    #=> {n3: "text/n3"}
