The MBP when completed will produce approximately 250 million pages or 500 billion characters of information. The storage requirements for the image files will be approximately 50 terabytes an order of magnitude larger than any publicly available information base. Creating and managing such a vast information base poses many technological challenges and provides a fertile test bed for innovative research in many areas (described below). The MBP is a multi-agency, multi-national effort that will require the database to be globally distributed. For location independent access, this globally distributed database should appear to be a virtual central database from any place around the world. Mirroring the database in several countries will ensure security and availability. The network speeds at the various nodes would be different. Research in distributed caching and active networks would be needed to ensure that the look and feel of the database is the same from any location.
