Raffles is a simple file-based RDF/Graph datastore written in PHP. It is written as a way to dynamically publish small datasets easily on PHP web hosting without using an external database.

Installation
------------

[](#installation)

composer create-project kwijibo/raffles raffles

see [Composer](http://getcomposer.org)

Creating a Store and Importing Data
-----------------------------------

[](#creating-a-store-and-importing-data)

```
    require 'Raffles/lib/rafflesstore.php';
    require_once 'Raffles/vendor/autoload.php';

    $data_dir = __DIR__ . '/data';
    $store = new RafflesStore($data_dir);
    $store->indexPredicates = array(
        'http://www.w3.org/1999/02/22-rdf-syntax-ns#type',
        'http://purl.org/dc/terms/creator',
        'http://purl.org/dc/terms/date',
    );
    // you can configure Raffles to only index specific predicates

    $store->addNamespacePrefix('library', 'http://purl.org/library/');
    // add prefixes you want to use in queries

```

### Getting types of things in the Store

[](#getting-types-of-things-in-the-store)

```
    $types = $store->getTypes();
    // array(
    // http://schema.org/Place => 321,
    // http://schema.org/Person => 456,
    //)

```

### Getting Facets

[](#getting-facets)

```
    $dates = $store->getFacets('http://purl.org/dc/terms/date');

    // array ( "1560" => 4, "1562" => 12, "1570" => 31  )

```

Basic Path query language
-------------------------

[](#basic-path-query-language)

`rdf:type=foaf:Person` (all things of type Person)

`foaf:made/dct:date=1780` (anyone who made something in 1780)

```
    $limit=20;
    $offset=0;
    $results = $store->query("foaf:made/dct:date=1560", $limit, $offset);

```

Results are returned as a PHP associative array following the [RDF JSON](https://github.com/iand/rdf-json) structure

```
    array (
    S => array(
        P => array (
          array(
              value => O,
              type => literal|uri|bnode
              [, lang=O_LANG ]
              [, datatype=O_DATATYPE ]
            )
        )
     )

```

Search
------

[](#search)

```
    $results = $store->search("Edinbu");

```
