Current Situation, earthquake monitoring:
- Web site A, B, C ...: fault, earthquake and other geo information
- Web services G, H, I ... : map, propagation, site response ...
- Web sites X, Y, Z ... : gov't emergency authorities
- Want to aggregate data to (for R&D or realtime alerts):
- compare network locations and compute new ones
- examine correlations of geophysical observations
- interface with authorities re: events and risks
Issues:
- Different databases, attributes, locations, services
- Different jargon, meanings
- Not easy to find, access, process resources
- Can do by building specialized systems => inefficient
