Cross-Domain Resource Discovery: Integrated Discovery

One of the primary goals of the project has been to develop (and implement with real databases) a search and retrieval system based on international standards that is capable of searching cross-domain resources held in multiple locations. This goal has been achieved, although even more resources and services have yet to be added to the system, and truly seamless integration of these services will require further development of additional “middleware”. We have developed and demonstrated technology for “harvesting” distributed databases and integrating the information in them into a hierarchical set of database selection servers that can be scaled to very large size without loss of performance.
