SDW –(Spatial Data Workbench) an Integrated Knowledge Management System for High-throughput Computational Ecology
•Collection Management System
SRB- (Storage Resource
Broker) Multiple, distributed, heterogeneous datasets managed as a single,
logical collection
TeraGrid computing - TeraGrid is a
multi-year effort to build and deploy the world's largest, fastest, distributed
infrastructure for open scientific research.
The Biomedical Informatics
Research Network (BIRN) Knowledge-based integration of
human/mouse brain, structural/functional MRI
ClimDB: LTER Climate
database - Integration
of distributed weather and hydrology data
SEEK: (Scientific
Environment for Environmental Knowledge)Modeling frameworks, semantic
integration, workflow systems for environmental modeling
Web
Services Fabric:
Catalog for service discovery,Network
Switches, routing tables, Network Director: monitor/ensure
Data grids Provide access to large distributed data sets, Focus on: naming
issues, hiding file access latency via HSM and remote I/O techniques
Distributed databases: Provide ability to query and
update data in distributed DBMS’s, Focus on: schema
integration, query optimization, transaction processing support
Open
Grid Services Architecture (OGSA) Everything
is a service, System
“transparencies” for data on the Grid, Location/Name: could be anywhere on the Grid, Distribution:
could be distributed across multiple locations, Replication: could be in more
than one location(s), Heterogeneity: could be in more than one format—file or
DBMS, points or polygons, etc… (the difficult one),
Ownership & Costing: should not have to negotiate with each source individually
GEON: (The Geosciences Network)
Close collaboration
between geoscientists and IT to interlink databases and Grid-enable
applications, “Deep” data modeling of 4D data, Situating 4D data in
context—spatial, temporal, topic, process, XML-based standards for data
exchange, Semantic integration of Geosciences data, Logic-based formalisms to represent knowledge
and map between ontologies
SOAP: Simple Object Access Protocol
Allow
the access of Simple Object over the Web
SOAP=XML+HTTP+standards
Web
Services Description Language
WSDL describes what a web
service can do, where it resides, and how to invoke it.
Universal
Description, Discovery and Integration
UDDI is a registry for
connecting producers and consumers of web services.
