Metadata

Metadata is data about the data.  There is no consistent way to present the metadata.  Many data sets use an XML file, but there is no single way to view the resulting files, and other files will have an HTML or TXT file, or even multiple files.  Microsoft Word or the browser might do a reasonable job, but often you will have to use the search function to find what you want,such as "datum" or "projection".  The file name will often include the word "meta".

XML uses tags like HTML, but the tags are specficic to the kind of data, like <datum>WGS84</datum>.   You want smart formating to see the various tages.
