Attributes

model: The RDF::Trine::Model which data will be extracted from. The only attribute which the constructor requires.
page_properties: An arrayref of RDF::Trine::Node::Resource objects, each of which are taken to mean "something a bit like foaf:homepage". There is a sensible default.
title_properties: An arrayref of RDF::Trine::Node::Resource objects, each of which are taken to mean "something a bit like foaf:name". There is a sensible default.
cache: A hashref for caching data into, or a blessed object which supports get and set methods compatible with CHI and Cache::Cache. If you do not supply a cache, then a hashref will be used by default.
