16. Cox/2005 AGU Spring Key Points e-Science depends on  Informational Services – to supply modelling constraints  Computational Services – to supply simulators and solvers e-Science community focus on “Grid” services  high-performance computing, PDE solvers – remote but tight connections  large datasets, data warehouses – simple data structures Geospatial community working on REST web-services  loosely-coupled, decision-support– on-demand discovery, binding and chaining,  detailed semantics – complex data-structures, community schemas
