The Collection Manager is where you start your collection building process; it allows you to easily manage and edit data templates and collection properties.
After creating the collection properties and using the LUNA Uploader to add content to a collection the collection can be immediately viewed in the LUNA Viewer. Any changes made to a collection are also immediately published.
There are only two tabs in the Collection Manager: Collections and Templates. With these 2 tabs you'll create and edit collection properties and work with data templates and schemata.
