A. Workshop Purpose    (419M)

This workshop will explore the emerging cyberinfrastructure landscape for robust, collaborative organizing, that recognizes the importance of infrastructure metrics and Service Oriented Architecture (SOA) to advance the performance capacity, reliability, and resilience of advanced networks. Today advanced network federation is fundamental to the high-performance of distributed communities at national and global levels and a SOA framework for performance measurement and analysis is a key element.    (41EA)

In this workshop, participants will explore the evolution of SOA-based approaches to extending the real-time discovery capacity for discernment around the parts/ whole performance profile and behavior of multi-institutional and heterogeneous networks intended to work well with one another. By defining and provisioning for a more granular level of performance measurement data through standards-based messaging services, the functioning of this complex web of network components can be understood and leveraged toward improvements that reflect cooperation and contributions across "autonomous" providers. To achieve effective evolution across a "whole" system that is fully owned and controlled by no party, sufficient performance data must be available to advance credible commitments and foresight from multiple forms of expertise. Such commitments, expressed in open standards, enable coherent, yet comprehensive data performance flows.    (41EB)

"Scientific experiments routinely send data over networks owned and operated by several different administrative domains. Isolating performance problems in this multi-domain environment is a challenging and time-consuming problem. A common framework that defines a suite of XML-based messaging services that allows the secure sharing of measurement and monitoring data is required to resolve this problem. The perfSONAR (PERFormance Service Oriented Network monitoring ARchitecture) framework provides a starting point for resolving these problems and will support future growth in this area." (Excerpt from Large-Scale Networking and Joint Engineering Team Performance Measurement Initiative draft white paper)    (41D9)

This half-day organizing workshop will open up dialogue to facilitate "bootstrapping" among multiple communities and institutions whose individual and collective contributions to shared design challenges will shape our national and global experience of networking capabilities for years to come. The impact of open standards frameworks for national and global capacity building at both strategic and solution levels will be highlighted by examining the forces, timing, and artifacts by which transformative standards emerge. Workshop finding and results will contribute to future Expedition Workshops in the coming year.    (419R)

It is likely that how we design our cyberinfrastructure (including stewardship and knowledge-sharing environments that influence policy-making, innovation, and agility) will play a pivotal role in the continued vitality and creativity of our 21st century democracy.    (419T)

Building on best practices from mature distributed science communities, participants will have the opportunity to learn and contribute to unprecedented challenges of scale and complexity, that impact not only scientific discovery and innovation, but also multi-institutional "virtual organizations" forming to address national challenges    (41EC)

This workshop will provide an example of how to set conditions by which groups that may not have regular opportunities to share information outside of their agency boundaries and jurisdictions can be brought together. This will support the development of a broader vision among stakeholders engaged in virtual organization challenges, from clean energy innovations to climate change mitigation strategies and beyond.    (419S)

In addition, this workshop will demonstrate an organizing process that can be employed anytime a purpose cuts across organizational boundaries. This is timely for workshop participants who have come to appreciate that building trusted relationships is the essence of eGovernment. How people design the organizing process for potentially “collaborative” settings, existing beyond traditional boundaries, can spell the difference between “multiplicative power” and “no power” arising to achieve high performance results that matter to all.    (419U)

In addition, as "reducing our carbon footprint" moves from slogan to global imperative, collaboration augmented by "silicon-based" collaborative work environments offers significant dividends. The "physical" carbon-based movement of people, goods, and services exacts a much higher carbon cost, than the "virtual" silicon-based movement of people's artifacts and intents - including ideas, knowledge, and requests/ acknowledgements around goods and services available through the World Wide Web. "Virtual Organizations" are poised to amplify effectiveness and timely results, including greater "buy-in" than is obtained through traditional ways of organizing.    (419O)

• To be of service, in cross-boundary settings, not only to the region, but to the nation    (41A1)
• To contribute to scientific discovery in service to society    (41A2)
• To learn by doing, to put into practice the results of our own dialogue    (41A3)
• To experience the kind of complex, multidimensional organizational situation that is providing the background for strategic leadership    (41A4)

B. Draft Workshop Questions    (41A5)

• 1. What aspects of organizing "virtual organizations" will most benefit from coordination that includes open dialogue in public settings?    (41A6)
• 2. Given the expressed needs for a multi-domain performance infrastructure:    (41DA)
  • 2.a How do we create commonly understood problem representations and simulations to help multiple disciplines and geographic regions build capacity for joint stewardship?    (41A7)
  • 2.b How can the right information and information structures support effective problem representation?    (41A8)
  • 2.c How can critical information from multiple sectors and domains be right "at hand", "in place", and appropriately accessed, when needed?    (41A9)
• 3. How can effective roles and responsibilities be established for a myriad of professionals from multiple settings who need to respond to uncertainties with effective collaboration in an ever-expanding, data and information-rich world?    (41AA)
• 4. What is the role of business narratives and case studies in advancing the shared understanding and governance required to mitigate risks?    (41AB)
• 5. How can effective narratives be assembled and presented for large-scale learning exercises and effective communications in real situations?    (41AC)
• 6. How can the artifacts of large-scale learning exercises and real events be preserved with sufficient integrity relative to provenance, completeness, and bias to leverage continuous improvements in readiness?    (41AD)
• 7. How can problem representation and knowledge emerging from multi-disciplinary efforts (e.g. scientific discovery and engineering innovation, public health, natural resources, public utilities, and critical infrastructures) be validated and valued as national assets?    (41AE)
• 8. What are the weakest links relative to the unprecedented scale and mix of people, process, and technology and how can they be remediated?    (41AF)
• 9. Can we see in the future of creative collaborative efforts a future that transcends what has passed?    (41AG)
• 10. What concrete steps are presently possible toward this future, including what institutions have a shared mission for improved law, science, innovation, and public policy as reflected in their strategic plans?    (41AH)
  • See more than 400 strategic plans rendered in Strategy Markup Language for ease of discovery, understanding, and comparability    (41AI)
• 11. What are the current and future contributions of light-weight aggregator tools for advancing discovery, shared understanding, and organizing that scales across individuals, communities of practice, and institutions? How can these tools help us be individually accountable for collaborative actions relative to shared purpose? Examples in use by this workshop community include: perfSONAR (PERFormance Service Oriented Network monitoring ARchitecture), wiki namesake pages,[http://et.gov Emerging Technology Life-cycle process and Strategy Markup Language (StratML)    (41AJ)
• 12. How could lightweight semantics complement open format, robust storage, and fluid search to help integrate disparate information sources that support better national preparedness?    (41AK)
• 13. How could authoritative versions of existing policies, regulations, and legal procedures currently in place, be complemented by a "collective wisdom" version in order to broaden opportunities for suggested improvements, harmonization across boundaries, and creation of "synthetic" documents for easier comparison and constrast across institutions?    (41AL)
• 14. How can public policy stakeholders tap Web 2.0 "build to share" principles being advanced by forward-looking information stewardship organizations in order to broaden common understanding of multi-faceted aspects of national/ global challenges and accelerate discovery of exemplary practices?    (41AM)
  • a) Digital data and information communities advancing sound approaches for electronically stored information. Examples include librarians, curators, web content managers, ontologists, researchers, artists, historians, data managers, and records managers.    (41AN)
  • b) Open Standards bodies and consortia    (41AO)
  • c) Universities and university consortia    (41AP)

• 15. How do we build from the best of past experiences and also draw upon generational differences and cyberinfrastructure opportunities in a manner that reinforces strengths? (e.g. tap software engineering techniques – fine grained recording of “Who did what” transparency at the code level)    (41AS)
• 16. How do we provide the right sets of information flowing into and out of "what if" mission-policy simulations, etc. so understanding flows broadly even when the learning is experiential?    (41AT)
• 17. What are the conducive conditions for the creativity and governance needed among networked improvement communities so results and implications flow in a timely manner into legal, public policy, and public preparedness channels?    (41AU)
• 18. If information-flow impediments across domains are similar, would solutions likewise be similar?    (41AV)
• 19. If solutions are similar across domains and an overall architecture emerges, what metrics do we need to provide analytical accountability and close the IT transactional lifecycle (cybernetic feedback loop) for continuous improvement? Is perfSONAR (PERFormance Service Oriented Network monitoring ARchitecture), an early example of this potential in a global setting?    (41AW)
