Where the Python XMP Toolkit can really shine, though, is when you are
converting an image from another format such as TIFF or JPEG into JPEG 2000.
For example::
>>> import requests
>>> r = requests.get('http://photojournal.jpl.nasa.gov/tiff/PIA17145.tif')
>>> with open('PIA17145.tif', 'wb') as fptr: fptr.write(r.content)

>>> xf = XMPFile()
>>> xf.open_file('PIA17145.tif')
>>> xmp = xf.get_xmp()
