Questions about serializing

Which serialization method is the most efficient?

Currently, the "nt" output format uses the most efficient serialization; "rdf/xml" should also be efficient. You can serialize to these formats using code similar to the following:

myGraph.serialize(target_nt, format="nt")
myGraph.serialize(target_rdfxml, format="rdf/xml")

How can I use some of the abbreviated RDF/XML syntax?

Use the "pretty-xml" format argument to the serialize method:

myGraph.serialize(target_pretty, format="pretty-xml")

How can I control the binding of prefixes to XML namespaces when using RDF/XML?

Each graph comes with a NamespaceManager instance in the namespace_manager field; you can use the bind method of this instance to bind a prefix to a namespace URI:

myGraph.namespace_manager.bind('prefix', URIRef('scheme:my-namespace-uri:'))

Does RDFLib support serialization to the TriX format?

Not yet. Note that RDFLib does support parsing TriX, however. But that's a different FAQ.
