                 Serendipity can be a funny thing, since small decisions or discussions
                 can have a lasting effect on the world around us. For example, in 1980–
                 81, David J. Bradley, a computer engineer at IBM, wrote a few lines of
                 code that would forever change the way that people interact with present-
                 day computers. Bradley introduced the three-key sequence combination
                 “CTRL+ALT+DEL.” In what he would later describe in an interview  as “not
                                                                           9
                 a memorable event,” Bradley’s few lines of code were designed specifically
                 to give developers a set of escape sequences to do administrative functions
                 before powering down a computer; the lines were never meant to be seen
                 by the general public. However, this three-key sequence has become one of
                 the primary methods that are used today to perform the actions of logging
                 on/off, locking, and powering down one’s computer. In much the same
                 serendipitous way, Dublin Core has surprisingly become one of the most
                 important metadata frameworks within the library community and beyond.
