Instead of focusing on specific, static semantic description schemes, emphasis and focus is placed on determining what is necessary and needed to create any type or kind of semantic description for content data in various applications such as MPEG-7. In particular, numerous semantic description tools are selected after examining the principles of cognitive science and category theory. These semantic description tools provide sufficient flexibility and power to create any type or kind of semantic description. Semantic entity tools and categorical structure tools were identified as necessary and needed to create any type or kind of semantic description. Semantic entity tools are tools that represent entities in a semantic description. Categorical structure tools are tools that represent categorical structures of semantic entities and relations among these categorical structures. The semantic entity tools and the categorical structure tools facilitate creation of a semantic mosaic description for content data from multiple semantic descriptions.
