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 (TRL
6
-
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

Gartner Technology Hype Cycle
Phases in the adoption of a new technology
•
"Technology Trigger"
–
The first phase of a Hype Cycle is the "technology trigger" or breakthrough, product launch or
other event that generates significant press and interest.
•
"Peak of Inflated Expectations"
–
In the next phase, a frenzy of publicity typically generates over
-
enthusiasm and unrealistic
expectations. There may be some successful applications of a technology, but there are
typically more failures.
•
"Trough of Disillusionment"
–
Technologies enter the "trough of disillusionment" because they fail to meet expectations and
quickly become unfashionable. Consequently, the press usually abandons the topic and the
technology.
–
Less visibility. More users.
•
"Slope of Enlightenment"
–
Although the press may have stopped covering the technology, some businesses continue
through the "slope of enlightenment" and experiment to understand the benefits and practical
application of the technology.
•
"Plateau of Productivity"
–
A technology reaches the "plateau of productivity" as the benefits of it become widely
demonstrated and accepted. The technology becomes increasingly stable and evolves in
second and third generations. The final height of the plateau varies according to whether the
technology is broadly applicable or benefits only a niche market

ECHO Web Service Registration
Lessons Learned & Recommendations
Based on this exercise, our understanding is:
1.
ECHO
8
supports Web Service Providers to register the Web
Service Interface and the Web Service Implementation objects.
2.
Web Service Providers need to have two types of accounts in
ECHO: one Service Provider account and at least one user
account. The user account(s) must be associated with the
Service Provider account.
3.
Two distinct WSDL files are needed: the Web Service Interface
WSDL and the Web Service Implementation WSDL. They should
be accessible on the web.
4.
Web Service Interfaces will be activated by ECHO Ops. A new
hosting URL will be provided by the ECHO system. We need
then to update Web Service Implementation WSDL file
accordingly to reference this new Web Service Interface URL.
5.
The Web Service Interfaces and the Web Service
Implementations will not be publicly discoverable and accessible
until they are activated by ECHO Ops.
Suggestions for Web Service Providers:
1.
First register the Web Service Interface then the Web Service
Implementation.
2.
Run discovery function to guarantee that the registered Web
Service Object is available before taking the next step.
3.
Use ECHO Extended Services Tool to fulfill Web Service Object
registration.
4.
Send emails directly to ECHO Ops at
echo@killians.gsfc.nasa.gov
for
any problems you may
encounter when registering Web Service Objects.
Suggestions for ECHO Operations Group:
1.
The ECHO Extended Services Tool only provides
Register/update/delete functionalities for Web Service Providers.
It would be better to support discovery functions.
2.
Remove unnecessary functions from the ECHO Extended
Services tool, or make them invisible to Web Service Providers.
3.
Our experiment is time
-
consuming. We encountered some
exceptions or problems in almost every step. A user guide for
Web Service Providers is highly needed. It not only shows one
step after another how they can fulfill all the tasks, but includes
some QoA sections for quick problem resolving.
4.
A guide for Web Service Users is also needed.
5.
ECHO Ops personnel are very helpful. It would be better if they
could be more responsive. Currently, users are supposed to
report any issue to an open email list. But some times,
"everybody is responsible" can come to mean "nobody is
responsible".
6.
The web site needs to correctly describe the “Extended Services
Tool” as application based.
7.
The Extended Services Tool provided on a specific ECHO
version’s web site needs to be modified to be in synch with that
version in terms of defaults and capabilities.

–
Limited assessment of use cases
•
Jointly addressing sensor web metrics with Metrics WG
–
Telecons and meetings held (e.g. session at the NASA Science
Technology Conference
2007
) to explore the evolving definition
of sensor web concepts and implications for defining success
metrics
•
Overlapping themes
-
Web Services and Semantics
•
Plans to develop use cases
–
Ecology/ land use
–
Weather
–
Disaster Response
•
And develop a sensor web wiki
NATIONAL AERONAUTICS

Sensor Web Metrics
•
Two perspectives on metrics:
1.
Measure to what degree a system approaches/meets the sensor web
definition (or ideal)
2.
Measure utility of the sensor web system (performance, productivity,
usability)
•
Current ideas
–
Explore the usefulness of developing a “sensor web readiness level”
assessment mechanism, ala TRL (technology readiness level)
–
Decompose sensor web concepts/components into identifiable, and
perhaps measurable, sensor web levels
–
Seek measures of the utility factor, for example
•
Performance (e.g. response time)
•
Productivity (e.g. outcome metrics like publications, new capability,
cost improvement, on
-
demand data acquisition, new products/
products on demand, new users, impact of standards use)
•
Usability (time spent on task, accessibility)
•
Joint session with Metrics on Thursday morning
