Relations,
such as inverse and transitivity, were also identified. For example, the
sightseeing concept is disjoint from the shopping concept.

properties. For example, a tourism organization has a telephone number, a fax
number, an address, and an e-mail.

concepts were represented in OWL in the following way:
