Creating a custom model

If you would like to define a custom model, in some cases you must first create a custom model to contain the new aspect and tags to be assigned by the user. In this example, the model uses a prefix of tag, the aspect is called tag:taggable, and the property is called tag:tags.

Example: Creating custom tags model

This example contains a sample implementation of the tags custom model and is defined in the tagsModel.xml file.

<?xml version="1.0" encoding="UTF-8"?>

<!-- Definition of new Model -->

<model name="tag:tagsmodel" xmlns="http://www.alfresco.org/model/dictionary/1.0">

   <!-- Optional meta-data about the model -->

      <!-- Definition of new Taggable Aspect -->

      <aspect name="tag:taggable">

      	<title>Taggable</title>

      	<properties>

      		<property name="tag:tags">

               <title>Tags</title>

      			<type>d:text</type>

      			<multiple>true</multiple>

      		</property>

      	</properties>

      </aspect>

   </aspects>

</model>
