+  Metadata can often be thought of as a label on some bit of information
+  that can be useful to people or computer programs trying to use the data.
+  Without metadata, the person or computer trying to use the original information
+  would have to just guess what the original data is about.
+  For instance, if you create a problem and neglect to say in the title or
+  subject of the problem what it is about, then a human who wants to use
+  that problem would have to read the problem itself to see what it was about,
+  which is much more difficult than just reading a title.
+  A computer trying to do the same thing would just be out of luck; it is

+ One example of metadata is the <title> of a web page, which usually shows

+  That's information about the web page itself, not actually part of the
