==What is DataFed?== DataFed is a web services-based software that non-intrusively mediates between autonomous, distributed data providers and users. (See [[Media:EM_DataFed_FASTNET_050720.pdf| EM DataFed FASTNET Article]]). The main goals of DataFed are: * Aid air quality management and science by effective use of relevant data * Facilitate the access and flow of atmospheric data from provider to users * Support the development of user-driven data processing value chains === Papers about DataFed=== [[Media:EM_DataFed_FASTNET_050720.pdf| DataFed and Fastnet: Tools for Agile Air Quality Analysis]]<br> [http://capita.wustl.edu/capita/capitareports/060730IGARS_Denver/060730_IGARSS06_Denver_Husar.ppt DataFed: An Agile, User-Oriented Air Quality Data System]<br> [http://capita.wustl.edu/capita/capitareports/070725IGARSS07_Barcelona/DataFed_IGARSS07_Barcelona_ER3.pdf DataFed: Mediated web services for distributed air quality data access and processing.]<br> [http://datafedwiki.wustl.edu/images/8/85/IEEE_SysJournalGEOSS_DataFed.pdf DataFed: An Architecture for Federating Atmospheric Data for GEOSS]<br> ==What is the architecture (form and function) of DataFed?== DataFed is designed in accordance with the [http://www.grss-ieee.org/managedfiles/PDF/GEOSSArchitecture.pdf GEOSS architecture]. <br> * DataFed provides standard interfaces ([http://esto.nasa.gov/conferences/ESTC2006/papers/a6p2.pdf data wrappers]) to heterogeneous distributed data * Fosters data integration and use with processing services and tools * Collects metadata and user-feedback on the federated datasets in [[2008-12-15_AGU_DataSpaces:_Using_Community_Workspaces_to_Enable_Rich_Air_Quality_Metadata|DataSpaces]] ==DataFed Resources and Tools for the User== The main resource of DataFed is access to over 50 distributed, air-quality relevant datasets. Each dataset can be explored and analyzed by tools for processing and visualization. For the user, the main components are: * [[Compact Catalog - Alphabetical| Data Catalog]] is used to find and access data. (See [http://capita.wustl.edu/capita/capitareports/061212FallAGU/061211AGU_AQDatasystem/061220catalog/061220catalog.html Catalog Screencast] - 1.3 minutes) * [http://webapps.datafed.net/datafed.aspx?dataset_abbr=AIRNOW Data Viewer] is for loading, overlay, and browsing any of the federated datasets. * [[DataFed_Wiki|DataFed wiki]] is an interactive workspace for the DataFed community. ==Air Quality Application Examples== Since 2004, the datasets and the tools of the federated data system have been used in several air quality application projects: * [[Exceptional Events| Exceptional Event Analysis]] * [[CATT| Combined Aerosol Trajectory Tool]] * [[FASTNET| Fast Aerosol Sensing and Tools for Natural Event Tracking]] == DataFed Presentations== <ask sort="Date" order="descending" limit="100" >[[Category:Presentation]][[Category:DataFed]][[Date:=+]][[Date:=*]][[Location:=*]][[Title:=*]]</ask> ---- [[Category:About]][[Category:DataFed]]
