Detailed Description

File holding the SMWRDFXMLSerializer class that provides basic functions for serialising OWL data in RDF/XML syntax.

Author

Markus Krötzsch Class for serializing exported data (encoded as SMWExpData object) in RDF/XML.

Member Function Documentation

makeAttributeValueString()

SMWRDFXMLSerializer::makeAttributeValueString (   $string )

protected

Escape a string as required for using it in XML attribute values.

Parameters

$string

string to be escaped

Returns

string

makeValueEntityString()

SMWRDFXMLSerializer::makeValueEntityString (   $string )

protected

Escape a string in the special form that is required for values in DTD entity declarations in XML. Namely, this require the percent sign to be replaced.

Parameters

$string

string to be escaped

Returns

string

serializeExpCollection()

SMWRDFXMLSerializer::serializeExpCollection ( SMWExpNsResource  $expResourceProperty, array  $collection,   $indent,   $isClassTypeProp  )

protected

Add a serialization of the given SMWExpResource to the output, assuming that an opening property tag is alerady there.

Parameters

$expResourceProperty	SMWExpNsResource the property to use
$expResource	array of (SMWExpResource or SMWExpData)
$indent	string specifying a prefix for indentation (usually a sequence of tabs)
$isClassTypeProp	boolean whether the resource must be declared as a class

Bug:

The $isClassTypeProp parameter is not properly taken into account.

Individual resources are not serialised properly.

serializeExpLiteral()

SMWRDFXMLSerializer::serializeExpLiteral ( SMWExpNsResource  $expResourceProperty, SMWExpLiteral  $expLiteral,   $indent  )

protected

Add to the output a serialization of a property assignment where an SMWExpLiteral is the object. It is assumed that a suitable subject block has already been openend.

Parameters

$expResourceProperty	SMWExpNsResource the property to use
$expLiteral	SMWExpLiteral the data value to use
$indent	string specifying a prefix for indentation (usually a sequence of tabs)

serializeExpResource()

SMWRDFXMLSerializer::serializeExpResource ( SMWExpNsResource  $expResourceProperty, SMWExpResource  $expResource,   $indent,   $isClassTypeProp  )

protected

Add to the output a serialization of a property assignment where an SMWExpResource is the object. It is assumed that a suitable subject block has already been openend.

Parameters

$expResourceProperty	SMWExpNsResource the property to use
$expResource	SMWExpResource the data value to use
$indent	string specifying a prefix for indentation (usually a sequence of tabs)
$isClassTypeProp	boolean whether the resource must be declared as a class

serializeNestedExpData()

SMWRDFXMLSerializer::serializeNestedExpData ( SMWExpData  $expData,   $indent  )

protected

Serialize the given SMWExpData object, possibly recursively with increased indentation.

Parameters

$expData	SMWExpData containing the data to be serialised.
$indent	string specifying a prefix for indentation (usually a sequence of tabs)

Member Data Documentation

$namespace_block_started

SMWRDFXMLSerializer::$namespace_block_started

protected

True if the $pre_ns_buffer contains the beginning of a namespace declaration block to which further declarations for the current context can be appended.

$namespaces_are_global

SMWRDFXMLSerializer::$namespaces_are_global

protected

True if the namespaces that are added at the current serialization stage become global, i.e. remain available for all later contexts. This is the case in RDF/XML only as long as the header has not been streamed to the client (reflected herein by calling flushContent()). Later, namespaces can only be added locally to individual elements, thus requiring them to be re-added multiple times if used in many elements.
