Current internet standards provide the people many options for processing and manipulation with spatial data but difficulties occur when temporal data are needed to be applied. Traditional relational databases widely used on the Internet are not designed to store temporal data and this fact limits the authors in developing more enhanced geographic models. This paper is comparing several data models and approaches for managing temporal data, their suitability especially for practical usage, e.g. performing difficult queries, analyzing managed data as well as supporting construction of specific data formats needed by different web applications.
