  3. Tech Infusion Working Group • Mission • Enable NASA’s Earth Science community to reach its research, application, and education goals more quickly and cost effectively through widespread adoption of key emerging information technologies • Scope • Information technologies that... • Provide capabilities critical to the ESD mission & vision • Have been substantially developed (TRL6-9) but have not been widely deployed • Cannot be obtained simply through reuse of mature subsystems or software • May be slow to adopt because of the unique characteristics of Earth science (e.g., high data volumes)‏ • Approach • Improve community understanding of the technology infusion process • Identify barriers and solutions to technology adoption • Use case studies to evaluate effectiveness of infusion processes • Identify and evaluate new and emerging technologies • Develop roadmaps for adoption of key technologies

  4. Describes 11 high-level capabilities comprising an Earth science information system capability vision Identifies technologies critical to achieving the vision Positions capabilities and technologies within a real-world scenario Used to develop a shared understanding of the vision within the community TIWG Activities Continue to review and maintain the Capability Vision Use the Capability Vision to identify technologies to study Align technology roadmaps to the Vision Need to align the Capability Vision to the Decadal Survey objectives Capability Vision for Earth Science Data Systems Assisted Data & Service Discovery Assisted Knowledge Building Scalable Analysis Portals Community Modeling Frameworks Interactive Data Analysis Seamless Data Access Interoperable Information Services Responsive Information Delivery Verifiable Information Quality Collaboration Environments Evolvable Technical Infrastructure

  5. Technology Infusion Process Stakeholder needs identification Science needs End user needs Data systems goals Available technologies Stakeholder needs and objectives Technology trends analysis Technology identification Validate and Prioritize Identified technology trends Candidate technologies Prioritized capability needs Capability vision Technology matching Technology gaps (new technology needs) Technology adoption evaluation New technology development Selected and prioritized technologies Infusion strategies Infusion planning Technology deployment Known infusion barriers 2009

  6. TIWG 2009 Activities • Maintained 5 active subgroups/focus areas • Infusion Process and Strategies • Subgroup lead: Steve Olding (GSFC/Everware-CBDI) and Joe Glassy (UMT) • Services Interoperability and Orchestration • Subgroup lead: Ken Keiser (UAH) and‏ Brian Wilson (JPL) • Semantic Web • Subgroup lead: Peter Fox (RPI) and Rahul Ramachandran (UAH) • Sensor Web • Subgroup leads: Karen Moe (ESTO)‏ and Michael Goodman (NSSTC/MSFC)‏ • Data Stewardship • Subgroup lead: Ruth Duerr (NSIDC)‏ • Conducted weekly telecons • Full working group & Data Stewardship (1st Thursday) • Process and Strategies (2nd Thursday) • Semantic Web (3rd Thursday) • Sensor Web (4th Tuesday) • Services Interoperability (4th Thursday)

  7. Process and Strategies

  8. Technology Radar - Tagging • Continued tagging “tiwg-radar” in Delicious • Regular reviews of tagged technologies • Looked at several alternative social tagging technologies – Twine, Diigo • Developing analysis approach to better understand and classify results • Poster: Wednesday 5:30 PM

  9. Technology Infusion Planning Identifying problems that create the need for innovations and surveying emerging technologies that might benefit the organization Innovations matched against the identified problems Implementation Agenda Setting Matching Redefining Clarifying Routinizing Initiation Decision Innovation adapted to the needs of the organization Gaining experience with the innovation - results in a better understanding of the benefits and costs Innovation is incorporated into the regular activities of the organization and looses its separate identity • Objectives • Understand the technology infusion process • Identify activities for each stage of the process • Document a standard infusion plan • Technology Infusion Process Workshop: Wednesday, Breakout Session 2

  10. Web-based Collaboration Technologies • Review of web-based collaboration technologies to support virtual organizations such as the working groups • Document sharing (Zoho, Google Docs) • General collaboration (SharePoint, wikis) • Web meeting, presentation sharing (WebEx, Vyew, DimDim)

  11. Service Interoperability and Orchestration

  12. Service Casting • Lightweight, distributed alternative to centralized services directories (e.g. UDDI) • Easy authoring of advertisements, extensible scast format (Atom syndication feeds) • Providers re-publish scasts when services change (provider in control) • Aggregation & discovery come almost for free (Feed readers, Google search) • Scalable discovery, no single service registry (many entities could aggregate scasts for search) • Current status • Developed feed examples for different service types • Developed a feed reader to aggregate and display a catalog of 'scasts‘ • Finalizing namespaces and verifying the standard. • Service Casting Workshop: Wednesday, Breakout Session 3/4 • More on service casting at http://sciflo.jpl.nasa.gov/scast/

  13. Federated OpenSearch • Distributed search problem is highlighted at last year’s ESDSWG meeting • Earth Science Data: Why So Difficult??!@#!! • Many different data sources with differences in structure and access. • Proposed standards-based approach using OpenSearch • Current status • Developed service examples. • Standardizing keywords • Finalizing interfaces for both request and response. • Federated OpenSearch Workshop: Wednesday, Breakout Session 3/4
