README

Provides persistence and basic lookup capabilities for collections of Wikibase entities.

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/entity-store to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on EntityStore 1.x:

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

Usage

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

All services are constructed via the EntityStoreFactory class:

use Queryr\EntityStore\EntityStoreFactory;
$factory = new EntityStoreFactory(
	$dbalConnection,
	new EntityStoreConfig( /* optional config */ )
);

$dbalConnection is a Connection object from Doctrine DBAL.

Writing values

For writing values, you will need either ItemStore or PropertyStore.

$itemStore = $factory->newItemStore();
$propertyStore = $factory->newPropertyStore();

The main write methods are "store document" and "remove document by id".

$itemStore->storeItemRow( $itemRow );
$itemStore->deleteItemById( $itemId );

Note that $itemRow is of type ItemRow, which is defined by this component. ItemRow represents all values in a row of the items table. It does not require having a fully instantiated Wikibase DataModel EntityDocument object, you just need the JSON.

Next to ItemRow there also is ItemInfo, which is identical, apart for not having the JSON. (Internally these share code via the package private trait ItemRowInfo.)

Querying values

This list is incomplete and serves mainly to give you an idea of what this library contains. To get a full list, look at the services you can construct via the store, and their interfaces.

Fetching an Item by id

$q42 = $itemStore->getItemRowByNumericItemId( 42 );

Property data type lookup

$lookup = $factory->newPropertyTypeLookup();
$propertyType = $lookup->getTypeOfProperty( $propertyId );

List item info

Get cheaply retrievable info on the first 100 items.

$itemInfoList = $itemStore->getItemInfo( 100, 0 );

Restrict the result to items of type "book", assuming 424242 is the numeric id of "book".

$itemInfoList = $itemStore->getItemInfo( 100, 0, 424242 );

List item types

This will get you numeric item ids that represent the types of the items ("instance of") in the system.

$itemTypes = $itemStore->getItemTypes();
