For example, the date is always part of an online order. When you rent a car it is for specific dates. Events in the world occur at specific times and usually have a finite duration. Transactions occur in a sequence, with the current state of a system depending on the exact history of all the transactions. Knowledge of the temporal relationships between transactions, events, travel and orders is often critical. OWL-Time has been developed in response to this need, for describing the temporal properties of any resource denoted using a web identifier (URI), including web-pages and real-world things if desired. OWL-Time focusses particularly on temporal ordering relationships. While these are implicit in all temporal descriptions, OWL-Time provides specific predicates to support, or to make explicit the results of, reasoning over the order or sequence of temporal entities. OWL-Time was developed in the Spatial Data on the Web Working Group (a joint activity involving&nbsp;W3C&nbsp;and the OGC).<\/p>\n<\/div>\n<\/div>\n<\/section>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview Temporal information is important in most real world applications.
