Organizations like ours (and we are not alone) are having second thoughts about how much metadata we share and with whom. Some are becoming skittish, because the tides have turned once again and quality metadata is in high demand. We decided at OER Commons, for example, to place an "all rights reserved" notice on our website (meaning, you can’t scrape metadata and reuse it), and a license for non-commercial use on our metadata, with the goal of working with partners who desire something more than faux collaboration.
Our business in life is not to succeed but to continue to fail in high spirits. -- Robert Louis Stevenson
