# RDF::TrineX::Compatibility::Attean(3pm)

Compatibility layer between Attean and RDF::Trine

## 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 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\>.
