Objective: Unified, networked access to geographically distributed data from
Observing Systems and Historical Data Archives (focus on in situ data) Method:
Integrate several new, modern and proven, off-the-shelf, Open Source, network-based applications and technology developments
CORBA/Java RMI Data Server – network middleware SGT - Interactive, Java graphics tools NdEdit - Interactive Java in-situ data selecting / subsetting tool LDAP - Directory Services XML - Automated metadata generation tool Habanero - Collaborative tool environment
Dual access: Web and desktop Java application Web help and tutorial

Uniform network access to distributed observational datasets
Sophisticated Java tools for subsetting large, irregular, in situ data collections
Data fusion and data download From a desktop Java application or the web
Modern, scalable off-the-shelf components Open Source Java, CORBA, LDAP, XML Free and low maintenance
Extensible Scalable Extensible to satellite, gridded products, model results Poised to utilize new networking technology (e.g.,network Quality
of Service, Collaboration) Significant technology spin-offs already realized
