2. Talk Summary • NEEScentral Overview • NEES accounts • Security • Interim File hierarchy • Telepresence • Future Plans

3. Data Sharing and Archiving Policy • Policies apply to both experimental and simulation data • Goals • No data lost • Ensure high quality data • Provide sufficient data/metadata to reproduce experiment • Investigators who create/collect data have a legitimate interest in benefiting from their investment of time and effort • Data timelines • Accessible to project participants as soon as it is recorded • Submitted to the permanent repository within 6 months of the end of the experiment/simulation • Made automatically accessible to the public no later than 12 months after the end of the experiment/simulation

4. NEEScentral Overview

5. What is NEEScentral? • Portal to all NEESit central services • Data Repository • “No Data Lost” • Interim File Hierarchy • Bulk Upload • Single File Download • Authentication • Single username and password across NEES resources • Authorization • Determines who has access to given NEES resources, such as research data • Coming soon: OpenSEES simulation portal

6. NEES accounts • NEES accounts give you access to • NEEScentral data repository • Telepresence capabilities • Equipment Site NEESpops • If you do not have an account, request one now at: • https://central.nees.org/acct • Forget your password? • https://central.nees.org/acct/forgotpass.php

7. Project Membership • All project members may • Create experiments, trials, and subfolders • Upload data and other documentation • Access (download/view) all parts of the project • Admins may • Delete subfolders and files • Add members to a project • NEESit Recommendation • Make IT staff the project contact for now • Example: rcclermont@ucdavis.edu, kritikosw@yahoo.com

8. Requesting Membership • You may see this when you try to access a project • Click on the request link to gain access to the project • Email will be sent to the project contact(s), who will grant you access (or not)

9. Data Security • Those who are not members of the project do not have access to the data • We have two staff members who have experience/training in the field of security who will keep your data secure • Current admin/member groups will be extended for NEEScentral 2.0 • Read only access groups • PI groups

10. Interim File Hierarchy

11. Interim File Hierarchy

12. Interim File Hierarchy (cont’d) • Designed for flexibility • Unlimited number of subfolders may be created • A note on deletion • ONLY allowed by the project admins • Files may be uploaded individually or in bulk • References • http://it.nees.org/documentation/library/data_metadata/000281.php

13. From The Top - Projects • Each NEESR and preNEESR should have its own project • Projects allow you to share data with other researchers • All NEES users may create/manage their own project

14. Documentation Subfolders • Exist at each level of the hierarchy • NEESit Recommendation • Place document(s) at the highest vertical level in the hierarchy where it is still relevant across the horizontal levels

15. Analysis Subfolders • Pre-test simulations, design parameter studies, and post-test simulations • Include all input and output files • Document any assumptions made • Note: NEESit exploring project level analysis • Generally, this will be a new experiment ?

16. Metadata • Add metadata at the highest level • Project/Experiment/Trial • Subfolders • Files • Current metadata fields are very high level • Title/Name • Description • Objective • Start/End Date • Add documents describing metadata when existing metadata fields are inadequate

17. Experiments • Typically at least one (or more) experiment(s) per research group associated with the NEESR • UC Davis – 3 centrifuge experiments • Reno – 1 shake table experiment • Texas – 1 field experiment • Washington – 1 centrifuge experiment • Purdue – 1 structural experiment • Washington/Berkeley/Davis – 1 analysis experiment • Experiment Setup • Documents describing test setup, instrumentation plans, designs for specimen components, etc

18. Trials • Minor changes to the configuration parameters defined at the experiment level • Some experiments have only 1 trial • Centrifuge tests typically have multiple trials • Trial Configuration: • Files describing specific differences in the experiment setup that make this trial unique

19. Trial Repetitions • Trials run multiple times without changes to setup/trial parameters • Data averaged to improve data quality • Trial repetitions store multiple data sets with no changes to setup/configuration

20. Trial Data • Unprocessed Data • Raw data files from data acquisition systems – sensor data, video, still images • Rawest data available from the DAQ systems • Converted Data • Data converted to engineering units and other simple conversations • Example: Voltage to strain/curvature/displacement • Corrected Data • Data revised to compensate for problems or eliminate noise • Include documentations describing modifications to the dat • Derived Data • Secondary and tertiary data products • Examples: plotting rotation from displacement transducers, plotting strain profiles along a specimen axis

21. Telepresence

22. flexTPS • Enables remote viewing and robotic control of live video over the internet • Recommended tool for sharing video during an experiment • Developed by Christopher Stanton, UT Austin

23. flexTPS (cont’d) • Only software required: web browser • Integrated with NEES authentication & authorization • Use your NEES account to access private streams • Record capabilities available for authenticated users • flexTPS User Guide • http://it.nees.org/documentation/library/telepresence/000219.php

24. RDV • Real-time Data Viewer • View time synchronized, streaming data • Live or archived • Developed by Jason Hanley, SUNY/Buffalo • Supported displays • Numeric in chart or tabular form • Video/Images in full resolution or scaled form • Text – Examples: log messages, chat, etc

25. RDV (cont’d) • Useful for remote collaboration during your experiments • Requires use of Data Turbine • See your IT admins or contact NEESit for details and/or assistance • Obtain RDV from • A NEESpop where you have access • http://it.nees.org/support/demos/turbine/RDV.jnlp • RDV User’s Guide http://it.nees.org/documentation/library/telepresence/000232.php

26. Future Work

27. NEEScentral • Enhanced metadata models across domains • Google search • PDF’s, Word/Excel documents, etc • Enhanced security • Read only access to projects • PI area • Bulk Download • Usability Enhancements • File browsers, project and member sorting, etc

28. NEES Web Template • Template for NEESR web sites • Enables researchers to easily share data • Only project members have access • Linked to NEEScentral data repository, local data repository, or both • Easily customizable • Easily extensive by IT staff • Interface to specific applications • Provide customized tools that integrate with the data repository

29. SingleShot • Christopher Stanton, UT Austin (Again!) • Supports NEESit interim hierarchy • Extended metadata model • Software Goals • Enable researchers to manage data locally • Synchronize with NEEScentral

30. NEES Activities Web Interface • Web site to communicate current status of NEES research • Publicly accessible for education and outreach • Communicates dates and times for tests • Highlights next four tests to occur • Provides access to public telepresence streams/movies

31. NEES Activities Web Interface (cont’d)
