NL LOM

NL LOM is the Dutch applicationprofile of LOM. This profile was constructed after a project by Stichting Kennisnet and SURFfoundation., _(*2)

In NL LOM the agreements 'Content-zoekprofiel' and 'LORElom' are merged to form a metadata agreement for Dutch education based on IEEE-LOM., _(*3)

Summary

This library offers a couple classes to simplify creating and parsing Lom objects and XML., _(*4)

The Lom class consists of multiple setters/getters which rely on data wrapped in a class. For example, setting the general language uses a value wrapped in a LomString object:, _(*5)

<?php
$lom = new NLLOM();
$lom->addGeneralLanguage(new LomString('nl'));

There are multiple types of these Lom wrapper classes, which can be found in the Library folder. For an example of creating a complete Lom record this way, check the unittest NLLOMTest.php in tests., _(*6)

Usage

Creating a new Lom object, _(*7)

 'en'
];

$lom = new NLLOM\NLLOM($options);

$lom->setGeneralTitle(
    new LomMultiLanguage([
        //Create different titles
        new LomLanguageString('Dit is een titel', 'nl'), //override default language
        new LomLanguageString('This is a title')
    ])
);
```

**Converting a Lom object to DomDocument**

```php
lomToDom($lom);

$result = $dom->saveXML();
```

**Converting existing Lom XML/DomDocument to Lom object** 
```php
load('lom_example.xml');

$mapper = new NLLOM\DomToLomMapper();
$lom = $mapper->domToLom($domDocument);
```

**Validation**
```php

<lom xmlns="http://www.imsglobal.org/xsd/imsmd_v1p2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.imsglobal.org/xsd/imsmd_v1p2 http://www.imsglobal.org/xsd/imsmd_v1p2p4.xsd">
    <general>
        <title>
            <langstring xml:lang="nl">Foobar</langstring>
        </title>
    </general>
</lom>
XML;
