Adding Metadata to a MOSS 2007 Publishing Portal pt2

Add three columns to the Content Type that you use for WCM. In this example I've used PageTitle, PageDescription and PageKeywords.

Add the assembly to the Master Page and reference the MetaData dll
<%@ Register TagPrefix="metaControl" Namespace="MetaData.Render" Assembly="MetaData.Render, Version=1.0.0.0, Culture=neutral, PublicKeyToken=198d2f392e054e3e" %>

Example: In the head
<metaControl:SharePointMetaTag runat="server" ID="metaTag1" MetaName="DESCRIPTION" MetaAttributeName="Content" PublishingPagePropertyName="PageDescription" DefaultAttributeContent=""/>


The DefaultAttributeContent is where the editor has not completed the field as we've made them non manditory
