The only metadata stored is a plain english description of the content. The format of a description metadata element is as follows:<br><br><code><metadata><br> <scheme><br> <name>description</name><br> <location><i>location of resource used to parse and query the scheme</i></location><br> <content-type>text/plain</content-type><br> </scheme><br> <i>plain english description</i><br></metadata></code><br><br>For an example of this class in use, see <a
