The valid-time temporal model provides an approach for consistently representing temporal information. In this model, a piece of information — which is often referred to as a ''fact'' or a ''proposition'' — can be associated with instants or intervals denoting the times that the fact is held to be true. Such facts have a value and one or more ''valid times''. In other words, every temporal fact holds information denoting the facts's ''valid-time''. Conceptually, this representation means that every temporal fact is held to be true or ''valid'' during the time or times associated with this fact. No conclusions can be made about the fact for time periods outside of its valid-time. {nid ASM} |
