Raptor Overview

I. Raptor Tutorial

Initialising and Finishing using the Library

Listing built-in functionality

Parsing syntaxes to RDF Triples

Introduction

Create the Parser object

Parser features

Set RDF triple callback handler

Set fatal error, error and warning handlers

Set the identifier creator handler

Set namespace declared handler

Set the parsing strictness

Provide syntax content to parse

Parse the content from a URI (raptor_parse_uri())
Parse the content of a URI using an existing WWW connection (raptor_parse_uri_with_connection())
Parse the content of a C FILE* (raptor_parse_file_stream())
Parse the content of a file URI (raptor_parse_file())
Parse chunks of syntax content provided by the application (raptor_start_parse() and raptor_parse_chunk())

Restrict parser network access

Filtering parser network requests with feature RAPTOR_FEATURE_NO_NET
Filtering parser network requests with raptor_www_set_uri_filter()
Filtering parser network requests with raptor_parser_set_uri_filter()
Setting timeout for parser network requests with feature RAPTOR_FEATURE_WWW_TIMEOUT

Querying parser static information

Querying parser run-time information

Aborting parsing

Destroy the parser

Parsing example code

Serializing RDF triples to a syntax

Introduction

Create the Serializer object

Serializer features

Declare namespaces

Set error and warning handlers

Provide a destination for the serialized syntax

Serialize to a filename (raptor_serialize_start_to_filename())
Serialize to a string (raptor_serialize_start_to_string())
Serialize to a FILE* file handle (raptor_serialize_start_to_file_handle())
Serialize to an raptor_iostream (raptor_serialize_start_to_iostream())
Serialize to an raptor_iostream and close iostream (raptor_serialize_start())

Get or construct RDF Triples

Send RDF Triples to serializer

Querying serializer run-time information

Destroy the serializer

Serializing example code
