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 ...

CPU time on multitask applications

Hello all, I'm using clock() function (from ctime) to realize how long it takes my threaded application to complete an algorithm.

NAME
RDF::vCard - convert between RDF and vCard SYNOPSIS
use RDF::vCard; use RDF::TrineShortcuts qw(rdf_string); my $input = "http://example.com/contact-data.rdf"; my $exporter = RDF::vCard::Exporter->new; my $data = join '', $exporter->export_cards($input); print $data; # vCard 3.0 data my $importer = RDF::vCard::Importer->new; $importer->import_string($data); print rdf_string($importer->model => 'RDFXML'); DESCRIPTION
This module doesn't do anything itself; it just loads RDF::vCard::Exporter and RDF::vCard::Importer for you. RDF::vCard::Exporter RDF::vCard::Exporter takes some RDF using the W3C's vCard vocabulary, and outputs RDF::vCard::Entity objects. RDF::vCard::Importer RDF::vCard::Importer does the reverse. RDF::vCard::Entity An RDF::vCard::Entity objects is an individual vCard. It overloads stringification, so just treat it like a string. RDF::vCard::Entity::WithXmlSupport RDF::vCard::Entity::WithXmlSupport is a subclass of RDF::vCard::Entity, with a "to_xml" method. It requires XML::LibXML to be installed and working. The importer and exporter will try to create these if possible. RDF::vCard::Line RDF::vCard::Line is internal fu that you probably don't want to touch. BUGS
If your RDF asserts that Alice is Bob's AGENT and Bob is Alice's AGENT, then RDF::vCard::Export will eat your face. Don't do it. Please report any other bugs to https://rt.cpan.org/Public/Dist/Display.html?Name=RDF-vCard <https://rt.cpan.org/Public/Dist/Display.html?Name=RDF-vCard>. SEE ALSO
