The new slice_owners table identifies all possible slice owners. Every slice has such an owner. A slice owner is not a physical person or a user in the user database, but rather an organization. The slice owner in the Action Applications acts as slice grouping and slice group tagging.
The new slice_owner table needs an administrative interface. On the slice edit page, a new field, a combo box, of slice owners, should be displayed. Every slice must reference to a valid slice owner. This information is stored in the new field owner in the slices table.
A link from the slice edit page must lead to a new slice owner edit page which is really simple: All slice owners are displayed with their names. The names come in text edit boxes. It is possible to add a new slice owner (text edit field and "add" button) and to change the name of exiting slice owners and resubmit the changes via a submit button at the end of the page.
