This standard developed to describe 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. OWL-Time also supports other representations of temporal position and duration, including temporal coordinates (scaled position on a continuous temporal axis) and ordinal times (named positions or periods).

Temporal information is important in most real world applications. 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 W3C and the OGC).
