Directly or indirectly (on various projects I consult on, advise,
design/implement for, or expect to), the following use cases for a web
ontology language would be important for me (by no means exhaustive):

1) conceptual/ontological search/retrieval and navigation, i.e.,
enchance search to be based on the semantics of concepts and relations.
2) to support web services, such as lookup, constraint satisfaction
(time, quality, cost), possibly control scheduling too. This covers a
lot of ground, so one simple case (a current project) is to find/support
a weather reporting service with some limited temporal constraints,
i.e., the forecast for next Sunday in Chicago.
3) to represent product/service catalogs in business-to-business
e-commerce and to assist in the semantic mapping from a
canonical/reference set of ontologies in the product and service space
to the individual ontology supported catalogs, for parameterized
(property, attribute) search.
4) to enable the fusion/composition of information from disparate
ontology modeled sources to a resolved or reference model (for
defense-related command and control decision-making, for example).
