WebProtege - Layout configuration

The WebProtege layout

The layout of WebProtege is configurable, and it can be easily adapted to different project requirements. The user interface layout is specified declaratively in a XML file. The layout can also be made specific for a project, or specific to a project and user.

The WebProtege user interface layout is composed of tabs, e.g. Classes Tab, Individuals Tab, Change History Tab, Notes and Discussions tab, etc.

Each tab can contain several portlets that are grouped in a column layout and make up the tab layout. For example, the Classes Tab shows on the first column a Class Tree portlet, and in the second column shows a properties portlet, a restriction portlet and a notes portlet.

Adding new tabs and portlets from the user interface

To add a predefined tab in the user interface, use the Add tab menu in the ontology toolbar (top right corner). To add portlets to a tab, use the menu Add content to this tab menu in the toolbar.

Note. It is possible to store the configuration by clicking on a Save Layout button, but in the current WebProtege release it is disabled. We will restore the functionality in one of the next WebProtege releases.

Pre-configuring the WebProtege layout

The configuration of the WebProtege layout is declarative through a XML file. The default configuration xml file is located in war/projectConfigurations/configuration.xml. The XML file contains spells out the layout of a project in terms of tabs and portlets. The example for the layout of the configuration of the Classes Tab is shown below:

<tab>
    <name>edu.stanford.bmir.protege.web.client.ui.ontology.classes.ClassesTab</name>
    <label>Classes</label>
    <columns>
      <column>      
        <width>0.33</width>
        <portlets>
          <portlet>
            <name>edu.stanford.bmir.protege.web.client.ui.ontology.classes.ClassTreePortlet</name>
            <height>600</height>
            <width>200</width>
          </portlet>
        </portlets>
      </column>
      <column>
        <width>0.66</width>
        <portlets>
          <portlet>
            <name>edu.stanford.bmir.protege.web.client.ui.ontology.notes.NotesPortlet</name>
            <height>0</height>
            <width>0</width>
          </portlet>
          <portlet>
            <name>edu.stanford.bmir.protege.web.client.ui.ontology.restrictions.RestrictionsPortlet</name>
            <height>0</height>
            <width>0</width>
          </portlet>
          <portlet>
            <name>edu.stanford.bmir.protege.web.client.ui.ontology.classes.AllPropertiesPortlet</name>
            <height>200</height>
            <width>0</width>
          </portlet>
        </portlets>
      </column>
    </columns>
    <controllingPortlet reference="../columns/column/portlets/portlet"/>
  </tab>

A tab is split into columns. The Classes Tab is split into two columns: the class tree column spans 33% of the layout, and the other column spans 66%.

Each tab should have a controlling portlet. The controlling portlet sets the selection for the rest of the portlets in a tab. For example, in the Classes Tab, the controlling portlet is the class tree portlet. This means that whenever the user selects a class in the class tree, that selection is transmitted to the other portlets in the tab to update their display.

The template of a project configuration XML file is:

<project>
<tabs>
  <tab>
    <name>my.tab.class.name</name>
    <label>My tab label</label>
    <columns>
      <column>
        <portlets>
          <portlet>
            <name>my.portlet.class.name</name>
             ... (other portlet properties)
          </portlet>
            .... (other portlets)        
        </portlets>
      </column>
       ... (other columns)
    </columns>
    <controllingPortlet reference="../columns/column/portlets/portlet"/>
  </tab>
   ... (other tabs)
  </tabs>  
</project>

If you want to create a custom configuration.xml file, it is a good idea to start from an existing one (e.g. the default configuration in the WebProtege distribution) and adapt it.

Adding your own tab or portlet in the configuration file

It is quite straightforward to add a pre-existing tab or portlet to the XML configuration file. First, find the class name of the tab or portlet that you want to add (the list at the end of this wiki page should help), and then insert the <tab> or <portlet> structure in the appropriate place in the configuration file.

For example, to add the change history portlet to a tab, insert the following lines in the configuration file:

<portlet>
  <name>edu.stanford.bmir.protege.web.client.ui.ontology.changes.ChangeSummaryPortlet</name>
  <height>600</height>
</portlet>

Sometimes, you would like to aggregate some portlets in a dummy tab. This corresponds in the user interface to the Add tab -> Add your own tab menu. To create a custom tab, you can just add in the XML configuration file a edu.stanford.bmir.protege.web.client.ui.tab.UserDefinedTab and add the portlets in it. Don't forget to specify the controlling portlet!
