Last night the Graduate Center of the City University of New York held a panel discussion with four museum professionals:
Christina DePaolo, Balboa Park Online Collaborative Michael Edson, Smithsonian Institution William Noel, University of Pennsylvania Neal Stimmler, Metropolitan Museum of Art
The web announcement for the event is here: http://cunydhi.commons.gc.cuny.edu/2012/11/07/wednesday-november-28-the-comm...
Although the evening was billed as a session on museums and digital humanities, it was devoted to thoughts, ideas and strategies about museums engaging with the digital world. Although Wikipedia was mentioned only once, all of these individuals appeared extremely determined to open their collections to the public through digitization, and creating/adding value to them by harnessing the knowledge of the communities that are attracted to them.
One of the questions at the end wondered why all the institutions used Flickr instead of their own websites. The responses made an argument for being "out there," that people will find the materials more easily when they're on Flickr than if kept within the museums' sites.
You can still catch most of the tweets if you search the hashtag: #cunydhi
I mention it here because they video-recorded the panel. I strongly suspect the video could become a forceful argument for convincing organizations to partner with GLAM-Wiki people. I'll watch out for when the video become available and maybe someone can post the link on the Wikimedia GLAM pages.
