simplified some wording for better understanding

    1: \label{Metadata_Description}
    2: 
    3: \index{Metadata}\label{What Is Metadata?}\emph{Metadata} is \emph{data about data}. Metadata can often be thought
    4: of as a label on some bit of information that can be useful to people or
    5: computer programs trying to use the data. Without metadata, the person or
    6: computer trying to use the original information would have to guess
    7: what the original data is about. For example, if you create a problem and
    8: neglect to say in the title or subject of the problem what it is about, then
    9: a human who wants to use that problem would have to read the problem itself
   10: to see what it was about, which is much more difficult than just reading
   11: a title. A computer trying to do the same thing would be out of luck;
   12: it is too stupid to understand the problem statement at all.
   13: 
   14: One example of metadata is the <title> of a web page, which usually shows
   15: up in the title bar of the browser. That is information about the web page
   16: itself and is not actually part of the web page. People use the title information
   17: when they bookmark a page. Search engines
   18: use it as a clue about the content of the web page.
