3. Long tail of data Volume of data Number of researchers Slide: The Institute for Empowering Long Tail Research 3

4. Open Data: OECD criteria Openness flexibility transparency legal conformity protection of intellectual property formal responsibility professionalism interoperability quality security efficiency accountability sustainability 4 Organization for Economic Cooperation and Development (2007) http://www.oecd.org/science/sci-tech/38500813.pdf

5. Purposes – Record of observations – Reference – Reproducibility of research – Aggregate multiple sources Users – Investigator – Collaborators – Unaffiliated or unknown others Time frame – Months – Years – Decades – Centuries http://chandra.harvard.edu/photo/2013/kepler/kepler_525.jpg Why sustain access to research data? 5

6. 6 Simplifying the Challenge

7. Big Science Little Science Large instruments High cost Long duration Many collaborators Distributed work Centralized data collection Small instruments Low cost Short duration Small teams Local work Decentralized data collection 7 Sloan Digital Sky SurveySensor networks for science

13. Envisioning the Digital Data Archive of the Future: A Case Study of DANS Users Data Archiving and Networked Services Andrea Scharnhorst, Henk van den Berg, Peter Doorn University of California, Los Angeles Christine Borgman, Milena Golshan, Ashley Sands DANS visiting scholars Herbert van de Sompel, Los Alamos National Lab Andrew Treloar, Australian National Data Service 13

14. Research Questions Who contributes data to DANS, when, why, how, and to what effects? Who acquires data from DANS, when, why, how, and to what effects? What roles do DANS archivists play in acquiring, curating, and disseminating data? 14

15. Knowledge Infrastructures for Data Archiving and Data Sharing Contributed data sets Data Archive Data sets selected for reuse

16. Economics of the Knowledge Commons 16 Subtractability / Rivalry LowHigh Exclusion Difficult Public Goods General knowledge Public domain data Common-pool resources Libraries Data archives Easy Toll or Club Goods Subscription journals Subscription data Private Goods Printed books Raw or competitive data Adapted from C. Hess & E. Ostrom (Eds.), Understanding knowledge as a commons: From theory to practice. MIT Press.
