Docs For Class RdfSerializer

Description

An RDF seralizer.

Seralizes models to RDF syntax. It supports the xml:base, xml:lang, rdf:datatype and rdf:nodeID directive. You can choose between different output syntaxes by using the configuration methods or changing the configuration default values in constants.php. This class is based on the java class edu.unika.aifb.rdf.api.syntax.RDFSerializer by Boris Motik.

Methods

Constructor RdfSerializer (line 53)

Constructor

access: public

RdfSerializer RdfSerializer ()

addNamespacePrefix (line 143)

Adds a new prefix/namespace combination.

access: public

void addNamespacePrefix (String $prefix, String $namespace)

String $prefix
String $namespace

configSortModel (line 79)

Serializer congiguration: Sort Model Flag if the serializer should sort the model by subject before serializing.

TRUE makes the RDF code more compact. TRUE is default. Default can be changed in constants.php.

access: public

void configSortModel (boolean $bool)

boolean $bool

configUseAttributes (line 105)

Serializer congiguration: Use Attributes Flag if the serializer should serialize triples as XML attributes where possible.

TRUE makes the RDF code more compact. FALSE is default. Default can be changed in constants.php.

access: public

void configUseAttributes (boolean $bool)

boolean $bool

configUseEntities (line 92)

Serializer congiguration: Use Entities Flag if the serializer should use entities for URIs.

TRUE makes the RDF code more compact. FALSE is default. Default can be changed in constants.php.

access: public

void configUseEntities (boolean $bool)

boolean $bool

configUseQnames (line 118)

Serializer congiguration: Use Qnames Flag if the serializer should use qualified names for RDF reserved words.

TRUE makes the RDF code more compact. TRUE is default. Default can be changed in constants.php.

access: public

void configUseQnames (boolean $bool)

boolean $bool

configUseXmlDeclaration (line 131)

Serializer congiguration: Use XML Declaration Flag if the serializer should start documents with the xml declaration <?xml version="1.0" encoding="UTF-8" ?>.

TRUE is default. Default can be changed in constants.php.

access: public

void configUseXmlDeclaration (boolean $bool)

boolean $bool

saveAs (line 287)

Serializes a model and saves it into a file.

Returns FALSE if the model couldn't be saved to the file.

access: public

boolean saveAs ( &$model, $filename, [String $encoding = DEFAULT_ENCODING], object MemModel $model)

object MemModel $model
String $encoding
&$model
$filename

serialize (line 161)

Serializes a model to RDF syntax.

RDF syntax can be changed by config_use_attributes($boolean), config_use_entities($boolean), config_sort_model($boolean). NOTE: There is only one default namespace allowed within an XML document. Therefore if SER_RDF_QNAMES in constants.php is set to FALSE and you pass another $xml_default_namespace as parameter, the model will be serialized as if SER_RDF_QNAMES were set to TRUE.

access: public

string &serialize ( &$model, [ $xml_default_namespace = NULL], [String $encoding = DEFAULT_ENCODING], object MemModel $model)

object MemModel $model
String $encoding
&$model
$xml_default_namespace
