In order to change the owner of a DataSet, click on the checkbox to left of the DataSet name and click Change Owner. Upon clicking the Change Owner link, a popup will appear that shows all of the users to whom you can assign the selected DataSet to. Once you select a user from the drop-down presented and confirm, that user will become the new owner of the locator. Only the owner of the DataSet and the Admin user can perform this action.
