This term is already in use, interchangeably with ``spatio-temporal,'' in the geographic information systems community (+E3) (hence, the preference over ``temporal-spatial''), and is consistent with the ``temporal'' modifier (+E7). Avoiding the hyphen makes it easier to type (+E2), another reason to prefer it over ``temporal-spatial''. It may be applied generically as a modifier for ``database,'' ``algebra,'' ``query language,'' ``data model,'' and ``DBMS.'
