        !             2: \index{Metadata}\label{What Is Metadata?}\emph{Metadata} is \emph{data about data}. Metadata can often be thought
        !             3: of as a label on some bit of information that can be useful to people or
        !             4: computer programs trying to use the data. Without metadata, the person or
        !             5: computer trying to use the original information would have to just guess
        !             6: what the original data is about. For instance, if you create a problem and
        !             7: neglect to say in the title or subject of the problem what it is about, then

        !            15: itself, not actually part of the web page. People use the title information
        !            16: when they bookmark a page, so they know what the page is. Search engines
        !            17: use it as a clue about the content of the web page.
