Abstract
The design space for representing temporal data in XML has thus far received limited empirical attention. As a result, designers do not fully understand the design space and trade-offs between various representational approaches. This thesis presents an initial characterization of that design space and provides a qualitative and quantitative analysis of the extreme ends of the spectrum, as well as an expressive language for describing temporal data. We extend an existing language, τXSchema, to implement three classes of representations and show that the edit-based scheme provides the best performance in terms of creation time and representation size, although the item-based and sliced-based schemes can be validated more quickly. We also provide an analysis of where temporal constraint functionality should be implemented and show that, with a few exceptions, temporal constraint functionality must be implemented within the tools and cannot be implemented in the representational schema. These results provide insight into the overall design space for temporal representations that will be useful to researchers, tool implementers, and users of τXSchema.
