NAME

RDF::TrineX::Compatibility::Attean - Compatibility layer between Attean and RDF::Trine

SYNOPSIS

In modules that have new Attean methods, but otherwise uses RDF::Trine, just go:

use RDF::TrineX::Compatibility::Attean;

DESCRIPTION

For now, only certain methods of Attean classes are supported. They are added to the respective RDF::Trine classes by this module. They are:

• RDF::Trine::Node::equals

• RDF::Trine::Node::ntriples_string

• RDF::Trine::Node::Resource::abs

• RDF::Trine::Node::Literal::value

• RDF::Trine::Node::Literal::language

• RDF::Trine::Node::Literal::datatype

• RDF::Trine::Model::get_quads

• RDF::Trine::Model::count_quads

TODO

I'm unsure on how RDF::Trine::Node::Literal::has_datatype should be treated. Attean implements RDF 1.1, where all literals have a datatype, so to Attean, has_datatype would always be true, but that would be surprising to Trine users. For now, I have chosen to solve this only at the output level, i.e. the RDF::Trine::Node::Literal::datatype will return the RDF 1.1 datatypes, but has_datatype is still false for what was in RDF 1.0 plain literals and language literals.

BUGS

One should be aware that this module is a hack to make legacy code run while being in transition to Attean. It was initially motivated by making RDF::RDFa::Generator run on both frameworks. It may do surprising things.

Nevertheless, please report any bugs or things you miss from Attean here: https://github.com/kjetilk/p5-rdf-trinex-compatibility-attean/issues.
