For what purpose? <meta> elements are hidden to user and machines don't need
yet another place to look. If you're concerned about validation (indeed even
if you aren't), change

<img src="http://ny-pictures.com/nyc/cc-icons/by.png" alt="by/2.0"
class="small_license">

to

<a href="http://creativecommons.org/licenses/by/2.0/" rel="license"><img
src="http://ny-pictures.com/nyc/cc-icons/by.png" alt="by/2.0"
class="small_license"></a>

and add nothing else.

That happens to work as RDFa, but validates and is also
http://microformats.org/profile/rel-license

But even if you don't want to add rel="license", add the link so users can
actually click. :-)

If you want to use meta elements you're doing the right thing by using
dcterms. Ask the DC folk about best practices and validators.
