Questions for SI What are SI deliverables, milestones and

schedules? What is NEESpop?

Where does it fit in our LAN? What are its specs? Who pays for it?

Connection between NEESsite and NEESgrid: Who will build it? Who will make it work and maintain it?

Questions for SI Will SI support:

OpenSees Matlab/Simulink MTS Scramnet

Will SI provide training? Who will pay for it?

How will SI provide Internet security for a NEESsite? Who will be responsible?

Questions for CD How will policy be established? What

mechanisms will be used to ensure that NEES policy is consistent with local policy at equipment sites?

What will be the relative roles of the consortium and the local equipment sites in setting access rules; use charges and personnel rates; schedules; outreach and advertising?

Questions for CD Data:

Who will choose data formats for archiving and exchange?

Who will determine when to release data? Who will have authorship rights?

Software: Who will ensure that appropriate software is

available for data archiving, visualization, simulation?

Who will fund development and maintenance of such software?

Questions for CD Researchers/students:

How will NEESsites be matched with researchers/students

Will student credit count for graduation at all NEES sites equally?

How will pay for educating the researcher/student on how to use the facility
