A method, interface, and apparatus for expressing data objects is described. A method for expressing information can comprise the steps of: extracting attributes of a plurality of data objects, wherein the attributes reflect information associated with the data objects; hierarchically grouping the data objects based on the attributes of the data objects to form a hierarchical data object structure; establishing basic representation units, wherein each basic representation unit is described using multimedia attributes and each unit corresponds to at least one data object; establishing a multi-dimensional mapping relationship between distinct attributes of a subset of the data objects that correspond to each basic representation unit and the multimedia attributes used to describe that unit and displaying the basic representation units to reflect the hierarchical grouping of the data objects on a multimedia display device, wherein the mapping relationship is used to determine the multimedia attributes of the basic representation units.
