In order to facilitate the editor's task of resolving issues raised in the commenting process, a special purpose form was designed (see Figure 4).
Figure 4: CASCADE Review Form
Any number of review forms may be visible at one time and they may be acted upon and disposed of in any order. There are radio-button selection boxes incorporated into the upper panel that allow categorization of a comment. The panel also displays information about the author of the comment, the date of the e-mail correspondence, and the name of the document section to which the comment is linked. The lower half of the form displays the content of the comment. The text entry field in the middle of the form is used to record notes about the comment being viewed or to justify classification decisions. (While text annotations are optional, CASCADE automatically documents and time-stamps any change to the classification of the comment.) A scrolling window is used so that long comments can be viewed while keeping forms small. Every exposure (i.e., viewing) of a comment is recorded in the transaction log and every visit that involves a change of selectors or writing of a remark is appended to the comment itself.
