Hi John,
I suspect you've seen this already, but you can use MediaWiki's external link
search to search for links to UNESCO. For example here's how to find links to
resources hosted at
en.unesco.org/mediabank in the commons:
https://commons.wikimedia.org/w/index.php?target=http%3A%2F%2Fen.unesco.org…
You can do searches like that on all the language Wikipedias. Maybe it could yield some
interesting data for analysis? If you're interested I have some code for collecting
the links automatically:

Also, a few years ago Liam Wyatt prepared a report for the National Museum of Australia
about their relationship with Wikimedia. Perhaps there are some ideas/approaches in there
that could be useful for your project?

Good luck!
