- 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 PDA’s (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

## 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

## 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 – “Moore’s 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

## 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

## 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 Fox’s 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)
