I just wanted to suggest that "clearing house" is very common terminology. It's been used within medical practice and within any other practices across this country for many years. It's just a place where you collect things, information, best practices, or whatever. People can then go into it and get information out of it—i.e., provinces or anyone who wants to see what other people are doing well.
