I’ve just released Graphite 1.4<\/a><\/p>\n

Graphite is a PHP library to allow quick scripting with RDF, designed to work on one, or a small number of linked RDF documents and produce a page.<\/p>\n

Most of the 1.4 features were added to facilitate Les Carr who was trying to use it to solve a problem. It now has a bunch more methods you can call on a list of resources; append,union,except,intersection and sort.<\/p>\n

This means you can now do:<\/p>\n


\ninclude_once(\"arc\/ARC2.php\");
\ninclude_once(\"Graphite.php\");<\/tt><\/p>\n


\n$graph = new Graphite();
\n$graph->ns( \"ecs\",\"http:\/\/rdf.ecs.soton.ac.uk\/ontology\/ecs#\" );<\/tt><\/p>\n

$base_interest_uri = \"http:\/\/id.ecs.soton.ac.uk\/interest\/\";
\n$graph->load( $base_interest_uri.\"rdf\" );
\n$graph->load( $base_interest_uri.\"web_science\" );<\/tt><\/p>\n

$rdf_people = $people = $graph->resource( $base_interest_uri.\"rdf\" )->all( \"-ecs:hasInterest\" );<\/tt><\/p>\n

$wsc_people = $people = $graph->resource( $base_interest_uri.\"web_science\" )->all( \"-ecs:hasInterest\" );<\/tt><\/p>\n

print \"<\/tt><div>Either RDF or Web Science: \".$rdf_people->union( $wsc_people )->sort( \"foaf:name\")->label()->join( \", \" ).\"<\/div>\";<\/tt><\/p>\n

print \"<\/tt><div>Both RDF and Web Science: \".$rdf_people->intersection( $wsc_people )->sort( \"foaf:name\")->label()->join( \", \" ).\".<\/div>;
\n<\/tt><\/p>\n

Which I think is beginning to get quite powerful, and remains reasonably easy to read.<\/p>\n

It also can now cache the RDF locally so you can save repeated HTTP requests when doing your linked-data thing.<\/p>\n","protected":false},"excerpt":{"rendered":"
