This bundle should include all files in the Picture of the Year competition for 2009
with the exception of any that may have been deleted by the time this bundle was put together
(January 22 2012).  The file poty-2009-media.tar.gz contains all of the media, latest
version only, full size.  The file Wikimedia-Commons-20120122182651-poty-2009.xml.gz 
contains the xml of all revisions for each description page of each file, in the
same format as used for our regular XML dumps of the projects.  See
http://meta.wikimedia.org/wiki/Data_dumps#Format 
http://meta.wikimedia.org/wiki/Help:Export#Export_format
for information on that format.

License: Licensing terms for each file should be included in the text of the xml
for the specific file.  You will see a heading such as 
== {{int:license}} ==
and immediately following, something like 
{{self|GFDL|cc-by-sa-all|migration=redundant}}

In this example, the file is dual-licensed under the GFDL and cc-by-sa.  Other examples
are: {{PD-art}} (public domain, work of art with copyright expired),
{{PD-USGov-Military-Air_Force}}, and so on.
