If you want to test quickly :

• Start a nuxeo
• Enable the development profile (Admin Center > Update Center > Studio > Click on the button)
• Restart
• In the file $NUXEO_HOME/nxserver/nuxeo.war/incl/tree_explorer.xhtml

Replace line 47 the following content

<h:outputText value="#{nxd:titleOrId(node.document)}" />

by the that

<h:outputText value="#{node.document.dublincore.creator}" />

If you are satisfied :

• create a bundle project
• in the src/main/resources/web/nuxeo.war/incl/ copy the modified file
• and create a file name deployment-fragment.xml with the following content

Here is the content of the file:

<?xml version="1.0"?>
<fragment version="1">

  <require>org.nuxeo.ecm.webapp.ui</require>

  <install>
    <!--  unzip the war template -->
    <unzip from="${bundle.fileName}" to="/" prefix="web">
      <include>web/nuxeo.war/**</include>
    </unzip>
  </install>

</fragment>
