LiteralTerm Class Reference

from PyKDE4.nepomuk import *

Inherits: Nepomuk.Query.Term
Namespace: Nepomuk.Query.LiteralTerm

Detailed Description

\class LiteralTerm literalterm.h Nepomuk/Query/LiteralTerm

Match literal properties via full text.

Other than the rest of the terms LiteralTerm has two uses:

Usage in ComparisonTerm

%LiteralTerm can be used in a ComparisonTerm with both properties with a literal range and a resource range. The former case is the simple one: the value() of the %LiteralTerm will simply be compared to the value of the ComparisonTerm.property(). In the latter case value() will be matched to rdfs:label of any resource. So in essence the following two examples are equal:

 ComparisonTerm( Vocabulary.NAO.hasTag(), LiteralTerm("nepomuk") );
 ComparisonTerm( Vocabulary.NAO.hasTag(), ComparisonTerm( Vocabulary.RDFS.label(), LiteralTerm("nepomuk") ) );

Usage as "stand-alone" term

As a term by itself %LiteralTerm will act like a traditional full text query and match all resources that contain the string value in some property.

 LiteralTerm( "nepomuk" );

The example above will match all resources that have a property with a value containing the string "nepomuk".
