The following provides information on the tables of the UserOptionRepository.
A UserOption applies to either Knowledge or Self Service. Users define user options by setting preferences in the Knowledge or Self Service preferences page. User options supersede segmented options and site options. The UserOption repository item references the user repository item by id rather than by item-type reference so we can use the same repository item to store options for both Knowledge and Self Service users. The UserOption repository item for Knowledge users is stored in the versioned /atg/svc/ServiceRepository although the option itself is not versioned. Self Service user options are stored in the unversioned ServiceRepository that self-service uses.
