ACCUMULATING A TAG CACHE FROM A PROFFERED DATASET

A tag accumulator tool includes, in an expanded mode, a proffered dataset of items for user selection, and a displayed accumulation area including a tag cache having, for each one of the selected data items, a respective corresponding tag. In a reduced mode, the tag accumulator tool displays an enumeration of the selected data items. A query box is operable to, upon entry of a character string, display a redacted list of selectable items including only those items of the proffered dataset at least partially matching the character string. Each tag in the accumulation area may include an annul tool the activation of which removes the tag from the accumulation area, effectively returning the corresponding data item to an unselected status.
