The main goal of B.R.I.D.G.E. is to profile databases from around the world with the most current information. Although we try to include as many profiles as possible, we unfortunately cannot profile every database. We work with each database manager to ensure their database profile is complete and accurate, as well as receive explicit permission for their database to be listed. Some reasons for declined participation are time constraints, non-commercial interests, and information disclosure restrictions. Here is a complete list of databases that declined to be profiled.
