QueryR TermStore

Stores terms of Wikibase entities to facilitate

• lookup of EntityIds given a term
• lookup of term(s) given an EntityId
• storing a Fingerprint for an EntityId
• removing all terms associated with an EntityId

System dependencies

• PHP 5.5 or later (PHP 7 and HHVM are supported)
• php5-sqlite (only needed for running the tests)

Installation

To add this package as a local, per-project dependency to your project, simply add a dependency on queryr/term-store to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on TermStore 1.x:

{
    "require": {
        "queryr/term-store": "~1.0"
    }
}

Usage

If you are curious what the database schema is, look at src/TermStoreInstaller.php.

All services are constructed via the TermStoreFactory class:

use Queryr\TermStore\TermStoreFactory;
$factory = new TermStoreFactory(
	$dbalConnection,
	new TermStoreConfig( /* optional config */ )
);

$dbalConnection is a Connection object from Doctrine DBAL.

Writing to the store

$writer = $factory->newTermStoreWriter();

$writer->storeEntityFingerprint( $entityId, $fingerprint );
$writer->dropTermsForId( $entityId );

Lookup up an EntityId based on terms

$idLookup = $factory->newEntityIdLookup();

$idLookup->getItemIdByLabel( $languageCode, $labelText );
$idLookup->getItemIdByText( $languageCode, $termText );
$idLookup->getIdByLabel( $languageCode, $labelText );

See the EntityIdLookup interface for all methods and their documentation.

Lookup label based on EntityId and language

$labelLookup = $factory->newLabelLookup();
$labelLookup->getLabelByIdAndLanguage( $entityId, $languageCode );

See the LabelLookup interface for documentation.
