When you select a vSphere object in the object navigator, the object workspace appears in the vSphere Web Client main workspace. Each object workspace contains a hierarchy of nested data views in a series of top-level tabs and second-level tabs.

You can add new data views to the tabs in any object workspace. The vSphere Web Client provides extension points for specific locations in each object workspace. For more information about the available extension points, see Defining Extensions.

When you create a data view extension for an object workspace, you must also provide the Flex and HTML classes that appear as the new GUI element in the interface. As a best practice, create these classes by using the same architecture, libraries, and services as the existing data views in the vSphere Web Client. See Creating Data View Extensions.

You can also add an object workspaces for a custom object that has the default structure and tabs. In general you create object workspace extensions to support custom vSphere object types that you add to the vSphere environment.
