Meeting Overview

• Selection of new community co-chair
• Chris Lynnes, ACCESS PI and Goddard Data Center
  Rep
• A huge Thanks to outgoing Co-Chair Rob Raskin
• Future technology focus and new key technology
  areas for evaluation
• Web services registries
• Use Cases
• Plenary sessions
• Sensor Webs
• Emerging technology tracking (hype cycle
  del.icio.us)
• Web Services and Semantic Web Demonstrations
• TIWG and hype cycle poster
• Joint working groups session
• With Metrics regarding metrics for sensor web
• With Reuse regarding Reuse Readiness Levels
  (similar to TRLs)
• Review of TIWG subgroups, goals and objectives
  for 2008
• Follow up with Laurie Schoppe/GSFC Tech Transfer
  Office

New Technology

• Client-side Tech Infusion
• Propose a joint activity with the ESIP Fed group
  of same name
• TIWG Liaison - Bruce Caron
• Explore specific objectives for TIWG
• Mashups involving portals, port-lets,
  machine-maching access
• Users and user interfaces
• client interfaces for both ends of the user
  spectrum, light weight to heavy desk top
  services
• service tier or N-Tier design in web environment
  (vs Grid where resources are managed)
• smart PDAs (iPhone) for end service points
  (scalable analysis) (use cases for science, for
  decision support)
• Portals
• Reuse, portal functionality via port-lets
  (reusable)
• infrastructure Spring, AJAX, Adobe AIR
• portals for machine interfaces (automatic
  discovery and use)
• Earth Visualization (AGU Visualization and
  Virtual Globes)
• Google earth, KML to OGC
• NASA World Wind
• Microsoft Virtual Earth

4
New Technology

• Workflows (as a follow up to web services)
• orchestration
• registration of services
• Asynchronous operations
• messaging and notification to enable offline
  workflow development that can then be launched
  asynchronously on line
• Mashups

5
New Technology Focus Area

• Suggested as a Focus Area
• Potential future sub group, depending on interest
  and future roles
• Explore technology implications of the area and
  report back to the TIWG
• TIWG Technical Infrastructure (TBD)
• Processing capability Moores Law has stopped
  implies need for parallel programming
• leverage gaming processors
• storage technology (laptop drives, iSCSI SANs)
• iPhone type of PDA
• networks
• TIWG Long-term Data Stewardship (Ruth
  Duerr/NSIDC)
• persistent identifiers (which standard to use
  how to ensure that standards longevity and use
  into the future)
• data attribution (how do users indicate which
  data they have used for metrics purposes, for
  science repeatability, etc.)
• provenance (how to record and track the
  provenance of the data in an automated and
  useable way)
• issues related to synchronization and separation
  of data from its metadata
• preserving the semantic and syntactic meaning of
  data over time (feeds directly into data access
  services)
• data quality measures

6
Sensor Web

• Collect Use Cases
• Help in clarifying role of metrics to support the
  underlying business decisions of NASA earth
  science and applications
• Several exist (e.g. WGISS, AIST projects, others)
• Develop capability road maps per sensor web
  dimension
• Autonomy - ability to reason about actions to
  take
• Architecture (standards interfaces)
• Communications
• Response time
• Data Info - raw, processed, metadata
• Draft Sensor Web Levels discussed but premature -
  need insights from use cases to proceed
• Explore relationship to WGISS for sensor web
  demonstrations

7
Tech Infusion Working Group

• Suggestions
• Conduct ESDS technology survey of all projects
• Welcome to TIWG for new PI participants
• Suggest activities to get started, like develop
  use case
• Contribute to technology survey
• Organize TIWG products for new public web site on
  ESDS tech infusion
• Roadmaps
• Assessment tools
• Capability vision
• Develop Earth Science Use Cases for Dummies,
  based on Peter Foxs tutorial

TIWG 2008 Activities

• Continue active subgroups
• Infusion Process and Strategies
• Subgroup lead Steve Olding
• Hype cycle implications
• Web Services -- transform into Workflows focus
• Subgroup lead Ken Keiser (UAH)?
• Co-lead Brian Wilson (JPL)
• Registry issues, ontologies for services,
  workflow technologies
• Semantic Web
• Subgroup lead Peter Fox (NCAR)?
• Co-lead Rob Raskin (JPL)
• Add semantics to services, more outreach (how
  to ontologies)
• Sensor Web
• Subgroup lead Karen Moe (ESTO)?
• Co-lead Michael Goodman (MSFC)

Start Tagging - To Detect Emerging Tech

• Go to http//del.icio.us/
• Register a new account
• Install the browser buttons
• Use the tiwg AND radar tags to identify new
  and emerging technologies of interest to the
  Earth science community
