Concept (LeDrew)
Past AQ at User and the GEOSS Architecture Workshop Series:
ESIP_Jan06: First public web service chaining demo
IGARSS06 Denver: Demo of web service chaining; GMU, JPL, WashU
IGARSS07 Barcelona: Sahara Dust; WashU with 12 NAM & EU data partners
Outcome: Successful Tech Demos but ‘SoS’ constructs fragile & uncontained

Application of OGC WCS Data Access Protocol
Regardless of the data location, data type and format,
• the parameter-space-time query is the same
• the return is in user selectable format from the offerings

Concept (con’t)
• Each role – identifies what data is required at that level– Determines how data should be packaged by GEO– Determines what is the customer base, what is the ‘chain of information’
• Includes data type, format, unit conversion, time resolution, quality control process, required fields, optional fields (Hans-Peter Plag: GEOSS User Needs and Performance Utility: Functional Spec and Database Structure)

System of SystemsGlobal Earth Observing System of Systems - GEOSS
Characteristics of System of Systems (SoS)
• Autonomous constituents managed/operated independently• Independent evolution of each constituent• SoS displays emergent behavior
Must recognize, manage, exploit the characteristics:
• No stakeholder has complete SoS insight• Central control is limited; distributed control is essential• Users, must be involved throughout the life of a SoS
![Page 12: 2008-05-05 GEOSS UIC-ADC AQ Scen W shop Toronto](https://reader036.vdocuments.us/reader036/viewer/2022062513/5554720cb4c905a5798b555a/html5/thumbnails/12.jpg)

Info System Challenges:

Cooperation, Competition, Co-Opetition

Organized Data
Flow of InformationData systems organize the measurements and models and provide them to programs.
Programs analyze the data and provide actionable knowledge to organizations.
Organizations evaluate multiple information sources, make decisions and act.
Flow of ControlPublic and special interest groups set up organizations and provides them with funding
Organizations develop programs, define their scope, governance and funding
Programs satisfy their information needs by monitoring or by using other’s data
Data sources acquire the data for their parent programs and also expose them for reuse

GEOSS Research:
• System of Systems Science• Network Science• Informatics Science
Science and understanding is poor in each areaGEOSS requires convergence of these sciences Leave science and convergence to serendipity?

Concept (con’t)• Team works through possible decision process to determine
whether, if GEO provided the information, the system will work as required.
• Product will be entries in tables and a narrative of processes• A product would be a list of best practices, one or more
of which will be entered into the GEO Best Practice Wiki (wiki.ieee-earth.org) .

Community Workspaces
• The Web is being transformed: It is becoming more participatory
– See the explosive growth of wikies, picture-sharing, blogs, Facebook – This architectural, technological and cultural change is Web 2.0
• Web 2.O is good for Earth Science community since it allows
– Better harvesting of current knowledge– However, many cultural, legal and other berries remain
• Workspaces may connect info providers, analysts, decision makers
• The challenge is to learn how to apply these tools GEOSS

AIP Process improvement ideas
Comments on AIP Process Process Improvement
Functionality defined by developers not users
UIC/ADC collab., Workshops;
Operational SBA functionality
AIP Process is closed Make development iterative; Anyone can join at anytime
Process focused on demonstrations
More operational persistence; Deliver AR-07-01 Operations
Too structured: milestones, deliverables
Retain structure within phase; More iterative, open approach
Adopted from Percivall, Feb 2008 by R. Husar
Contact with UIC; Toronto, Workshop;
Open Invitations, ESIP, CoP wiki
Expand AQ Data Netw; Seek link to AR-07-01
