The Goal
• Analyze, visualize, access
• Data of any type and from anywhere
• Intuitively, flexibly, professionally
An infrastructure to integrate data and services

The Simpler Is Better
• No software to install
• No need to learn data formats
• No need to do programming
• No need to download large amount of data

Core technologies
• Web services– Workflow (WS-BPEL, sciflo, Apache ODE)– OpenGIS (WCS, WMS)
• Math ML– Presentation/content– Function extension– Parse and execution
