# RDF::Trine::Parser::OwlFn(3pm)

OWL Functional Syntax Parser

## NAME

RDF::Trine::Parser::OwlFn - OWL Functional Syntax Parser

## SYNOPSIS

```
        use RDF::Trine::Parser;
        my $parser = RDF::Trine::Parser->new('owlfn');
        $parser->parse_into_model($base_uri, $data, $model);
```

## DESCRIPTION

### Methods

Beyond the methods documented below, this class inherits methods from the RDF::Trine::Parser class.

- "new(\\%options)"

  The only option supported is `"filter"` which can be used to tell the parser to ignore certain potentially boring triples.

  ```
    $flt = RDF::Trine::Parser::OwlFn::ANNOTATION
         + RDF::Trine::Parser::OwlFn::ANNOTATION_ANNOTATION;
    $parser = RDF::Trine::Parser->new('owlfn', filter=>$flt);
  ```

  The following constants are defined for filtering purposes:

  - •

    `"ANNOTATION"` - axiom annotations

  - •

    `"ONTOLOGY_ANNOTATION"` - ontology annotations

  - •

    `"ANNOTATION_ANNOTATION"` - annotation annotations

The usual `"parse_*"` methods accept an argument `"prefix_handler"` which can take a coderef which is called every time a prefix is defined by the ontology being parsed. The coderef is called with two arguments: the prefix being defined (including trailing colon), and the full URI as a string.

The `"parse_*"` methods return a string containing the remainder of the input (i.e. potentially a tail which could not be parsed).
