RDF::Core - An object oriented Perl module to support RDF.
Besides the basic querying, there is a query language implemented. The query language is focused on resource, not statement and the typical pattern is me->neighbor->child->age to express neighbour's children's age, not (me,neighbour, him) && (him, child, it) && (it, age, value). It contains some shortcuts to express things, that are (possibly) expressed often, like object->rdf:type = someClass. Functions are another enhancement of the language. They can be used instead of resource or property. Functions are implemented in a separated library, so that it's easy to create new or modify existing ones.
We focus on acceptable and clean interface between parts of the module. Typically a storage should have it's interface on a 'statement level' (add statement, get statement) rather then on data elements level (add this value into hash_one and that into hash_two), which comes with interface based on lower level base.
RDF::Core includes the following modules. See documentation for particular modules for details:
