Building Time Aware Applications in RDF

HPL-2009-6 Building Time Aware Applications in RDF - McBride, Brian
Keyword(s): semantic web, temporal RDF, temporal query, temporal modeling, temporal application.
Abstract: Several techniques for using RDF to model change over time in a domain are reviewed and a new approach with a lower triple count than previous approaches is described. It is argued that the application programmer requires tool support so that she does not have to deal with the details of the modelin ...

NAME

       RDF::Query::Algebra::TimeGraph - Algebra class for temporal patterns

VERSION

       This document describes RDF::Query::Algebra::TimeGraph version 2.908.

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.

       "new ( $interval, $pattern, $time_triples )"
	   Returns a new TimeGraph structure.

       "construct_args"
	   Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.

       "interval"
	   Returns the time interval node of the temporal graph expression.

       "pattern"
	   Returns the graph pattern of the temporal graph expression.

       "time_triples"
	   Returns the triples describing the time interval of the temporal graph.

       "sse"
	   Returns the SSE string for this algebra expression.

       "as_sparql"
	   Returns the SPARQL string for this algebra expression.

       "type"
	   Returns the type of this algebra expression.

       "referenced_variables"
	   Returns a list of the variable names used in this algebra expression.

       "potentially_bound"
	   Returns a list of the variable names used in this algebra expression that will bind values during execution.

       "definite_variables"
	   Returns a list of the variable names that will be bound after evaluating this algebra expression.
