Deploying Custom Content Model
• There are two approaches to deploying a content model into the content repository:
 Bootstrap
 The bootstrap approach to deploying a content model involves modifying Alfresco content repository XML
configuration files to register the content model.
 Dynamic
 Placing the content model xml files under Company Home/Data Dictionary/Models.
