The Semantic Web extends existing World Wide Web (WWW) with formal machine readable semantics that enable better understanding of Web content by both, people and machines. The OWL ontology language forms the basis of Semantic Web technologies by providing the means for defining formal semantics of concepts and their properties. Semantic Web standards also provide with the formalism and mechanisms for supporting reasoning and querying of information in OWL.Qualitative spatial and temporal information is supported using sets of SWRL rules and OWL axioms offering a sound, complete and tractable reasoning procedure based on path consistency applying on the supported sets of relations. Polynomial time complexity of spatio-temporal reasoning is achieved by restricting the supported sets of relations to "tractable" sets. Furthermore, rules enforcing cardinality constrains on dynamic properties are defined. Reasoning support for qualitative information and restriction checking is also introduced in this work for increasing expressive power of existing approaches. Building-upon existing Semantic Web standards and on the idea of integrating reasoning support into the proposed representation are important advantages of the proposed approach.Query support in SOWL is realized with two languages referred to as TOQL and SOWL Query Language. Both, are high-level query languages, independent from the underlying SOWL representation so that, the user need not be familiar with the peculiarities of the ontological spatio-temporal representation in SOWL (i.e., the 4D-fluents or the N-ary approach). TOQL handles ontologies almost like relational databases and relies on the idea of extending SQL with spatiotemporal operators. Respectively, SOWL builds-upon SPARQL, the current standard of the Semantic Web, which is also extended with a set of spatio-temporal operators similar to those introduced in TOQL.

This article proposes a crisp-based approach for representing and reasoning about concepts evolving in time and of their properties in terms of qualitative relations (e.g., “before”) in addition to quantitative ones, time intervals and points. It is not only suitable to handle precise time intervals and points, but also imprecise ones. It extends the 4D-fluents approach with crisp components to represent handed data. It also extends the Allen's interval algebra. This extension allows reasoning about imprecise time intervals. Compared to related work, it is based on crisp set theory. These relations preserve many properties of the original algebra. Their definitions are adapted to allow relating a time interval and a time point, and two time points. All relations can be used for temporal reasoning by means of transitivity tables. Finally, it proposes a crisp ontology that based on the extended Allen's algebra instantiates the 4D-fluents-based representation.
