Cox/2005 AGU Spring Overview e-Science / NERC Datagrid  Oceans & Atmospheres data Solid Earth and Environment community  HPC services for simulation & inversion Standards-based loosely-coupled data services  SEE Grid

Cox/2005 AGU Spring NERC DataGrid - data transfer e.g. Climate Science Modelling Language (CSML) ProfileFeature GridFeature ProfileSeriesFeature Focus on large datasets, simple structures  Time-series, profiles, gridded datasets  Series and collections BADC

Cox/2005 AGU Spring Some solid-earth e-Science/Grid projects GEON  NSF “Cyberinfrastructure” EarthByte  Sydney University/Caltech/CSIRO APAC Geosciences  Australian Partnership for Advanced Computing pmd*CRC  Cooperative Research Centre for Predictive Mineral Exploration

Cox/2005 AGU Spring Status quo: Different formats and standards Data Structures Proprietary Software Versions of Software User

Cox/2005 AGU Spring Open Geospatial Consortium - Web Feature Service GML WFS Server Data-source organised for custodian’s requirements Community-specific GML application language  TigerGML, LandGML, O&M, XMML, CGI-GML, ADX, GPML, CSML, MarineXML etc private  public boundary WFS Client HTML

Cox/2005 AGU Spring Standard transfer format allows multiple data sources WFS Client WFS Server WFS Server B WFS Server C

Cox/2005 AGU Spring Same format and standards User GML for geochemistry: XMML and OGC O&M XMML

Cox/2005 AGU Spring XMML data packet Inductively coupled mass spectrometry ICPMS Ag e-8 Ag All this (and more) required to properly transmit one number!

Cox/2005 AGU Spring PIRSA DOIR GA Mapping client Three servers, one map

Cox/2005 AGU Spring Report client Three servers, one report

Cox/2005 AGU Spring One service – many uses GML-based data can be …. Rendered into a queryable map … … formatted into a report or …. … read and used by any WFS/GML enabled application Condition: community-standard data model/encoding

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
