As you may have seen in the media, or on social media, today, Heritage England, who maintain the country's list of, er, listed buildings, have launched a crowd-souring initiative, asking people to provide information and images about listed buildings.
It's a horribly missed opportunity - it seems no thought has been given to collaborating with the Wikimedia movement, who have been colleclting such pictures on Commons (not least as "Wiki Loves Monuments") and writing about the buildings for over a decade, on Wikipedia.
Nor are people submitting images asked to put them under open licence. They claim their terms, at:
http://historicengland.org.uk/terms/website-terms-conditions/enriching-the-l...
allow the images to be used on Wikipedia, but that's not so.
I'm in contact with them, and am hoping to have a phone chat with the project manager later today. I'll keep you informed.
