Raptor parser, serializer or XML writer options.

RAPTOR_OPTION_SCANNING

If true (default false), the RDF/XML parser will look for embedded rdf:RDF elements inside the XML content, and not require that the XML start with an rdf:RDF root element.

RAPTOR_OPTION_ALLOW_NON_NS_ATTRIBUTES

If true (default true) then the RDF/XML parser will allow non-XML namespaced attributes to be accepted as well as rdf: namespaced ones. For example, 'about' and 'ID' will be interpreted as if they were rdf:about and rdf:ID respectively.

RAPTOR_OPTION_ALLOW_OTHER_PARSETYPES

If true (default true) then the RDF/XML parser will allow unknown parsetypes to be present and will pass them on to the user. Unimplemented at present.

RAPTOR_OPTION_ALLOW_BAGID

If true (default true) then the RDF/XML parser will support the rdf:bagID attribute that was removed from the RDF/XML language when it was revised. This support may be removed in future.

RAPTOR_OPTION_ALLOW_RDF_TYPE_RDF_LIST

If true (default false) then the RDF/XML parser will generate the idList rdf:type rdf:List triple in the handling of rdf:parseType="Collection". This triple was removed during the revising of RDF/XML after collections were initially added.

RAPTOR_OPTION_NORMALIZE_LANGUAGE

If true (default true) then XML language values such as from xml:lang will be normalized to lowercase.

RAPTOR_OPTION_NON_NFC_FATAL

If true (default false) then illegal Unicode Normal Form C in literals will give a fatal error, otherwise just a warning.

RAPTOR_OPTION_WARN_OTHER_PARSETYPES

If true (default true) then the RDF/XML parser will warn about unknown rdf:parseType values.

RAPTOR_OPTION_CHECK_RDF_ID

If true (default true) then the RDF/XML will check rdf:ID attribute values for duplicates and cause an error if any are found.

RAPTOR_OPTION_RELATIVE_URIS

If true (default true) then relative URIs will be used wherever possible when serializing.

RAPTOR_OPTION_WRITER_AUTO_INDENT

Automatically indent elements when seriailizing.

RAPTOR_OPTION_WRITER_AUTO_EMPTY

Automatically detect and abbreviate empty elements when serializing.

RAPTOR_OPTION_WRITER_INDENT_WIDTH

Integer number of spaces to use for each indent level when serializing with auto indent.

RAPTOR_OPTION_WRITER_XML_VERSION

Integer XML version XML 1.0 (10) or XML 1.1 (11)

RAPTOR_OPTION_WRITER_XML_DECLARATION

Write XML 1.0 or 1.1 declaration.

RAPTOR_OPTION_NO_NET

Deny network requests inside other requests.

RAPTOR_OPTION_RESOURCE_BORDER

Border color of resource nodes for GraphViz DOT serializer.

RAPTOR_OPTION_LITERAL_BORDER

Border color of literal nodes for GraphViz DOT serializer.

RAPTOR_OPTION_BNODE_BORDER

Border color of blank nodes for GraphViz DOT serializer.

RAPTOR_OPTION_RESOURCE_FILL

Fill color of resource nodes for GraphViz DOT serializer.

RAPTOR_OPTION_LITERAL_FILL

Fill color of literal nodes for GraphViz DOT serializer.

RAPTOR_OPTION_BNODE_FILL

Fill color of blank nodes for GraphViz DOT serializer.

RAPTOR_OPTION_HTML_TAG_SOUP

Use a lax HTML parser if an XML parser fails when read HTML for GRDDL parser.

RAPTOR_OPTION_MICROFORMATS

Look for microformats for GRDDL parser.

RAPTOR_OPTION_HTML_LINK

Look for head <link> to type rdf/xml for GRDDL parser.

RAPTOR_OPTION_WWW_TIMEOUT

Set timeout for internal WWW URI requests for GRDDL parser.

RAPTOR_OPTION_WRITE_BASE_URI

Write base directive for Turtle/N3.

RAPTOR_OPTION_WWW_HTTP_CACHE_CONTROL

HTTP Cache-Control: header

HTTP User-Agent: header

RAPTOR_OPTION_JSON_CALLBACK

JSON serializer callback function.

RAPTOR_OPTION_JSON_EXTRA_DATA

RAPTOR_OPTION_RSS_TRIPLES

Atom/RSS serializer writes extra RDF triples it finds (none, rdf-xml, atom-triples)

RAPTOR_OPTION_ATOM_ENTRY_URI

Atom entry URI. If given, generate an Atom Entry Document with the item having the given URI, otherwise generate an Atom Feed Document with any items found.

RAPTOR_OPTION_PREFIX_ELEMENTS

Integer. If set, generate Atom/RSS1.0 documents with prefixed elements, otherwise unprefixed.

RAPTOR_OPTION_STRICT

Boolean. If set, operate in strict conformance mode.

RAPTOR_OPTION_WWW_CERT_FILENAME

String. SSL client certificate filename

RAPTOR_OPTION_WWW_CERT_TYPE

String. SSL client certificate type

RAPTOR_OPTION_WWW_CERT_PASSPHRASE

String. SSL client certificate passphrase

RAPTOR_OPTION_NO_FILE
