It's a ZIP archive.  The info you've found are the file name
"mimetype", the uncompressed contents of that file
"application/vnd.oasis.opendocument.text", and part of the ZIP magic
number "PK".  You should be able to use the "zipfile" module to check
to see if the file a ZIP file, if it has a member named "mimetype" and
if the contents of the file match one of the OpenOffice MIME types.
