# RDF::Trine::Serializer::Notation3(3pm)

Notation 3 Serializer

## NAME

RDF::Trine::Serializer::Notation3 - Notation 3 Serializer

## SYNOPSIS

```
 use RDF::Trine::Serializer::Notation3;
 my $serializer = RDF::Trine::Serializer::Notation3->new();
```

## DESCRIPTION

The RDF::Trine::Serializer::Notation3 class provides an API for serializing RDF graphs to the Notation 3 syntax.

The output of this class is not optimised for human-readability; it's a data dump. The only minor concession it makes to human readers is that it will nicely indent formulae. I do have plans to port cwm's Notation 3 output to Perl, but this is likely to be distributed separately due to licensing concerns.

*Caveat scriptor:* while RDF::Trine::Node::Formula understands quantification (@forAll, `@forSome`), RDF::Trine::Model does not. This means that `@forAll` and `@forSome` defined in the top-level graph are not-round-tripped between the Notation 3 parser and serialiser (the parser will give you warnings about this). `@forAll` and `@forSome` within formulae will work fine.

### Constructor

- "new"

  Returns a new Notation 3 serializer object.

### Methods

- "serialize\_model\_to\_file ( $fh, $model )"

  Serializes the `$model` to Notation 3, printing the results to the supplied filehandle `"<$fh"`\>.

- "serialize\_model\_to\_string ( $model )"

  Serializes the `$model` to Notation 3, returning the result as a string.

- "serialize\_iterator\_to\_file ( $file, $iter )"

  Serializes the iterator to Notation 3, printing the results to the supplied filehandle `"<$fh"`\>.

- "serialize\_iterator\_to\_string ( $iter )"

  Serializes the iterator to Notation 3, returning the result as a string.
