Workspace content is made up of modules.
Module
A content item, such as an iView or page, which runs in a workspace page. In addition to the functionality of an iView or page, a module can also respond to workspace events. Workspace modules are created from module templates.
Module template
A template from which actual modules can be created in workspace pages.
Module templates can be of the following types:
Out-of-the-box (supplied by enterprise workspaces)
Based on portal content or URLs
Based on content external to workspaces
