[edit] Notes/Snippets
- Demonstrate usefulness of DataFed to individual providers, users and mediators.
- Network effect will produce value to the overall community
- Classes of particpants involve providers, users and mediators
- Classes of services: data access services, processing services, display control services and connectivity wrapper/adapter services.
- DataFed architecture utilizes adaptors and wrappers to facilitate networking for DataFed:
- Wrapping heterogeneous data was initially thought to be useful for networking-computer accessible legacy data systems that could not be changed at their source. The wrapper can be provided by a third party.
- Adaptor services are connectors between information systems with well-defined and stable input/output
- Networking Standards:
- Loosely coupled workflows from reusuable service components can be created by using wrappers and adapters.
- Wrappers have flexible inputs that are adaptable specificity of a specific data provider and standardized outputs.
- Adapters have standardized inputs from providers, but flexible outputs to adapt to the needs of specific clients.
- Relationship to National Air Monitoring Strategy(NAMS)
- NAMS was designed to produce more reusable datasets for multiple programs/applications in EPA
- Information System needs to facilitate the access, processing/analysis/integration of broad range of data to multiple applications
- Relationship to GEOSS and EPA OEI
- Explain GEOSS: International/Interagency; Multi-Sensory; System of Systems;
- GEOSS Approach: Build on existing systems; Publish reusable components; Integrate through international standard interfaces
- GEOSS Architecture: Service Oriented Architecture;
- GEO ESIP Coordination Links

[edit] Impediments, Barriers to entry, maintainance
- Networking involves bidirectional flow of information between nodes (data/feedback)
- Impediments to network connectivity - Technical/Cultural/Administrative:
- Impediment to exposing data/info (Stove pipe)
- Impediment to taking data/info (NIH)
- Barriers to entry
- ..
