     * The default priority of a page is 0.5.

     * influence the position of your URLs in a search engine's result pages.
     * Search engines may use this information when selecting between URLs on

  sources like Apache Nutch, Apache HTTP Server, the file(1) command, etc.

  Notes:
   * Tika supports a wider range of match types than Freedesktop does
   * Glob patterns must be unique, if there's a clash assign to the most
     popular format
   * The main mime type should be the canonical one, use aliases for any
     other widely used forms
   * Where there's a hierarchy in the types, list it via a parent
