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.

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 2.0Web 2.0 Web 2.O is good for Earth Science community since it allows –Better harvesting of current knowledge –Collaborative creation new knowledge.

Distributed Web Content Workspace Discussion Knowledege is created – reports, proposals…

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 Smoke images, were also found searching Flickr and GoogleFlickr 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 YouTubeYouTube Visually pruned blogs, videos and images were bookmarked and tagged fore later analysisvideosimagestagged

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.us RSS 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!
