Catmandu provides a suite of perl modules to ease the import, storage, retrieval, export and transformation of metadata records.

catmandu::rdf contains modules for handling rdf data within the catmandu framework. rdf data is encoded/decoded in aref as implemented with rdf::aref. please keep in mind that rdf is a graph-based data structuring format with specialized technologies such as sparql and triple stores. using catmandu::rdf to transform rdf to rdf (e.g. conversion from one rdf serialization to another) is possible but probably less performant than decent rdf tools. catmandu::rdf, however, is more conventient to convert between rdf and other data formats.
