An embodiment includes determining semantic attributes of a bookmark. The embodiment also includes determining respective attribute values for each of the semantic attributes of the bookmark. The embodiment also includes rendering a three-dimensional (3D) virtual space for display to a user, where the virtual space is defined by three orthogonal axes, each associated with a respective one of the semantic attributes. The embodiment also includes displaying a symbol representative of the bookmark in the virtual space. The symbol is positioned in the virtual space at an intersection of perpendicular projections from locations on the three axes corresponding with respective attribute values of the attributes associated with the respective axes.
