Introduction 

The Item Mapper is a tool in the DSpace web user interface allowing repository managers to display the same item in multiple collections at once. Thanks to this feature, a repository manager is not forced to duplicate items to display them in different collections

Using the Item Mapper

In the  User Interface, the item mapper can be accessed when editing an Item.

• Login as someone with Edit permissions
• Search/browse to the Item
• Click the "Edit this Item" button
• Click "Mapped" collections" button on the "Status" tab
  • You'll be shown a list of currently mapped collections (if any)
  • You can also map the item to a new collection by clicking on "Map new collections" tab, and searching for the Collection(s) 

Implications

Mapping collection vs Owning collection

The relation between an item and the collection in which it is mapped is different from the relation that this item has with the collection to which it was originally submitted. This second collection is referred to as the "owning" collection. When an item is deleted from the owning collection, it automatically disappears from the mapping collection. From within the mapping collection, the only thing that can be deleted is the mapping relation. Removing this mapping relation does not affect the presence of the item in the owning collection. 

Mapping an item does not modify access rights

When an item gets mapped into a collection, it does not receive new access rights. It retains the authorizations that it inherited from the collection that "owns" it. Collection admins who do not have read access to an item will not be able to map them to other collections.
