pdsinterop / flysystem-rdf example snippets

// Create Formats objects
$formats = new \Pdsinterop\Rdf\Formats();

// Use an adapter of your choice
$adapter = new League\Flysystem\Adapter\Local('/path/to/files/');

// Create the RDF Adapter
$rdfAdapter = new \Pdsinterop\Rdf\Flysystem\Adapter\Rdf(
    $adapter,
    new \EasyRdf\Graph(),
    $formats,
    'server'
);

// Create Flysystem as usual, adding the RDF Adapter
$filesystem = new League\Flysystem\Filesystem($rdfAdapter);

// Add the `AsMime` plugin to convert contents based on a provided MIME type, 
$filesystem->addPlugin(new \Pdsinterop\Rdf\Flysystem\Plugin\AsMime($formats));

// Read the contents of a file in the format it was stored in
$content = $filesystem->read('/foaf.rdf');

// Read the contents of a file in another format from what was stored in
$convertedContents = $filesystem
    ->asMime('text/turtle')
    ->read('/foaf.rdf');

// Get the MIME type of the format the requested mime-type would return
// This is especially useful for RDF formats that can be requested with several
// different MIME types.
$convertedMimeType = $filesystem
    ->asMime('text/turtle')
    ->getMimetype('/foaf.rdf');

// This also works for `has`
$hasConvertedContents = $filesystem
    ->asMime('text/turtle')
    ->has('/foaf.ttl');

// Without using the plugin, this will be false
$hasContents = $filesystem->has('/foaf.ttl');

// Create Flysystem as usual, adding an adapter of your choice
$adapter = new League\Flysystem\Adapter\Local('/path/to/files/');
$filesystem = new League\Flysystem\Filesystem($adapter);

// create and add the RdF Plugin
$plugin = new \Pdsinterop\Rdf\Flysystem\Plugin\ReadRdf(new \EasyRdf\Graph());
$filesystem->addPlugin($plugin);

// Read the contents of a RDF file in another format from what was stored in
$content = $filesystem->readRdf('/foaf.rdf', \Pdsinterop\Rdf\Enum\Format::TURTLE);
