Abstract
In this paper, we define Context as a data structure that gives the meaning and the environmental information of the detail data, and discuss two of its main features-nested structure and role dynamism. Then we propose a Context Model that unifies detail, meta and contextual data. We also discuss a Context-oriented query mechanism and illustrate the model by query examples.
