RDF-Patch Export

## NAME

RDF::Trine::Exporter::RDFPatch - RDF-Patch Export

## VERSION

This document describes RDF::Trine::Exporter::RDFPatch version 1.019

## SYNOPSIS

```
 use RDF::Trine::Exporter::RDFPatch;
 my $serializer = RDF::Trine::Exporter::RDFPatch->new();
```

## DESCRIPTION

The RDF::Trine::Exporter::RDFPatch class provides an API for serializing RDF graphs to the RDF-Patch syntax.

## METHODS

- "new ( sink =\> $sink )"

  Returns a new RDF-Patch exporter object.

- "comment ( $c )"

  Serializes a comment with the given string.

- "emit\_operation ( $op, @operands )"

  Serializes an operation identified by the character `$op`, followed by `@operands` (separated by a single space) and a trailing DOT and newline.

- "add ( $st )"

  Serializes an add/insert operation for the given statement object.

- "delete ( $st )"

  Serializes a delete operation for the given statement object.

- "statement\_as\_string ( $st )"

  Returns a string with the supplied RDF::Trine::Statement object serialized as an RDF-Patch string.

- "terms\_as\_string\_list ( @terms )"

  Returns a list with each supplied term serialized as RDF-Patch strings.

- "node\_as\_concise\_string"

  Returns a string representation using RDF-Patch syntax shortcuts (e.g. PrefixNames).

## NOTES

As described in "as\_ntriples" in RDF::Trine::Node::Resource, serialization will decode any punycode \<http://www.ietf.org/rfc/rfc3492.txt\> that is included in the IRI, and serialize it using unicode codepoint escapes.
