Metadata and linking are nicely illustrated by the way they are used to enhance photos. We expect future cameras (including cell phones) will automatically label every photo with time and place using embedded location hardware. Thus a photo can be recalled by a label, by time when taken or place where taken, or by subject, etc. Eventually, we expect software to analyze a photo’s content to create additional metadata. At present, our software allows photos to be geo-located by dragging and dropping them onto a map to “link” a location with a photo. Alternatively, a common timestamp.
