AQ Science Problems Complex
• Needs: – Multiple datasets– Multiple Tools – DIVERSE Community of People
• Underlying data infrastructure is being developed to accommodate data flow, still need for higher level information transfer
Web 1.0 Web 2.0
• web changing, making it easier to connect• Architecture of Participation - data/information (links, pictures,
videos, blogs) continuously popping up • Because it is on the internet data can be harvested and reused
(user-centric view) in ways not anticipated by the provider• Because it is a network can collaborate with people you don’t
even know
Harvested Resources
2000 Blogs on Florida Smoke
Smoke
Online Picture Sharing
215 Photos
Online Video Sharing 100 videos
Additional Value-added
• Low level of collaboration is sharing/harvesting resources• Next step is to add additional context, create a product
(analysis, report, proposal…)• Web as a platform provides open space to form a workgroup• Groups may be permanent (formal research groups) or ad hoc,
project specific groups.
Tools that enable these groups
• Allow for collecting and sharing artifacts – common procedures, tags
• Sharing a virtual workspace – Web is read/write now any page is editable with an edit button
• Opens the process up to allow unanticipated group members at any point in time to join and contribute
DataFedwiki
• Known group – our research group that uses it• Provides a place to stash ideas during discussions, share with
members not present and remember/re-use later• Archives presentations, with additional metadata like notes
made when preparing the presentation or other pieces that also were included (KML, screencast, links etc)
GEOSS AIP Workspace
• Ad hoc group formed around common interest in having input into the Air Quality Scenario CFP
• Collectively wrote the CFP • Captured key dialogue and discussion pertaining to the
scenario development… Key in creating a reusable scenario is having archive of process
Data Summit/ Community AQ Data System
• Invited group formed pre-Summit in order to profile the existing data systems
• Meeting activities were captured and workgroup/space evoloved
• Now Use wiki to capture group decisions, discussions, documents
CF Naming Conventions
• Proposed names, discussed, modified and then submitted names
• Because it was open, we have pointed others to these pages as a process for creating standard names.
Sustainable Air Quality Class Workspace
• The class harvested resources, gathered data, and wrote a class report using the wiki;
• Their workspaces were different from the others described, because the output on each space was a final report. The history of the page, shows the evolution that each group took as they gathered data, wrote, and modified throughout the semester.
Benefits of the workspace
• Collect distributed content and provide context. – Currently, there is flickr for photos, del.icio.us for links provide URL
for metadata about photo or link – workspace provides URL for a project.
• Workspaces can be easily set up and evolve for the group needs
• Allow new users to easily be caught up to speed in as little or as much detail
• Provides rich archive of discussion, resources and process the group took as well as the outcome
• Because it is web-based unanticipated others may be able to use some part of the work.
Mashup of Tools through Interoperability Standards RSS, RDF, KML and XSL

Information Overload
• Science problems are becoming increasingly complex • Information comes from both inside and outside the
organization (sometimes from people we don’t know)• Web is the platform
The Information Interoperability Stack
Web 1.0 -> Web 2.0 Transformation
• The Web is being transformed: It is becoming more participatory
• Its content is increasingly generated and distributed by individuals
• See the explosive growth of wikies, picture-sharing, blogs, Facebook
• This architectural, technological and cultural change is Web 2.0
• Web 2.O is good for Earth Science community since it allows
– Better harvesting of current knowledge– Collaborative creation new knowledge.

Connectivity of Humans
• Sharing specific artifacts – Pictures– Links– Videos– Blogs
• Shared workspace
Sharing Artifacts - May 07 Georgia/Florida Fires:
Community-Supplied Observations
Google and Technorati blog seaches yielded entries on GA Smoke.
. Smoke images, were also found searching Flickr and Google
Searching and pruning user-contributed Internet content yielded rich, but qualitative description of the May 07 Georgia Smoke Event.
Videos of smoke were found on YouTube
Visually pruned blogs, videos and images were bookmarked and tagged fore later analysis
Connectivity of Machines
• Web services • Service Orchestration • Mash-ups
Community Data Sharing - ‘DataSpaces’
Catalog - Find Dataset
Describe Dataset
Discuss Dataset
Earth Science Information Partners (ESIP)
• Semantic Wiki: Structured (RDF and Unstructured Content
• Open, Standard Matadata - RDF
• Ready for Export/Harvesting by Registries, Catalogs
Communal Event Analysis Southern California Fire Smoke
Approach (Blogs, Flickr, YOuTube):
Use app to perform coarse filtering Controlled tagging in del.icio.usRSS feed from del.icio.us
Wiki as a workspace
• Examples: Wikis, google groups, myspace, facebook ... • Collaboratively write and discuss
– Versioning/archive – open
• User-defined layout/Structure – Relational - tag-based, not hierarchical folders
• Organize different kinds of content - wiki can harness and integrate other services but it's up to user to assemble the parts in an innovative way - Situational applications – Small pieces loosely joined – Mash through RSS feeds or URL – upload docs – creating "records" on wiki pages
Wiki as a workspace
• Organize/collect distributed material and provide context for a topic
• Collaboratively create a document (report, proposal, presentation etc…)
• Discuss issues relating to topic• Act as an archive for the topic and group interactions
surrounding it. • The wiki platform is conducive for this because it allows
material distributed all over the web to be virtually 'mashed' together in one place through RSS feeds or iframe tags and elaborated on with relevant context and discussion. Because all of these elements are brought together in a workspace, the critical community knowledge is often captured as it is created.
Class?
• Used as class website with Syllabus/material • Answered questions about class on the wiki• Students organized and carried out their class project on the
wiki. • Established a set of key resources for next year’s class (Re-
usable)
Summary
• The participatory web architecture and technologies are here
• Standards are emerging for sharing previously unstructured data
• The entry resistance to any particular Web 2.0 tool is rather low
• However, many cultural, legal and other barriers remain
• The challenge is to learn how to apply these tools for Earth Science
Thank You!
Static versus Dynamic Research Projects
• Email only• Powerpoint slides• Pdf reports• Sharing/publication only of final
results
• Email + shared web workspaces
• Screencasts, WebEx• Multi-author content creation• Sharing/publication of workflow
(data to information)

Data Sources
• Observations & Models– Surface– Satellite– Forecasts
• News• Blogs (Technorati)• Photos (Flickr) • Links (Del.icio.us)• Videos (YouTube)• What you collect and generate
