1. Speeding Nano Progress by Accelerating the Spread of Knowledge Walt Warnick, Ph.D. Director, Office of Scientific and Technical Information U.S. Department of Energy

2. Three Topics Relating to Nano Info Diffusion  Modeling – it’s possible  Metadata – numeric data, unlike textual data, requires metadata to ensure access  Stewardship – numeric data could follow model of textual STI management

3. OSTI’s mission To advance science and sustain technological creativity by making R&D findings available and useful to DOE researchers and the American people. OSTI’s creed Knowledge is contagious – it’s our job to make sure everyone “catches” it!

4. OSTI corollary: If the sharing of knowledge – or knowledge diffusion – is accelerated, scientific progress is accelerated Science Progresses as Knowledge Is Shared

5. Diffusion of Feynman Diagrams From: The Power of a Good Idea: quantitative modeling of the spread of ideas from epidemiological models, Luis M. A. Bettencourt, Ariel Cintron-Arias, Carlos Castillo-Chavez; David Kaiser Discovery path of US and UK authors The Spread of Knowledge about Feynman Diagrams

6. The Spread of Knowledge Is Consistent with Diffusion Models Path of Best Trajectory From Report for the Office of Scientific and Technical Information: Population Modeling of the Emergence and Development of Scientific Fields; Luis M. A. Bettencourt, Carlos Castillo-Chavez, David Kaiser, David E. Wojick

7. The Spread of Knowledge Can Be Accelerated Paths of Acceleration Bettencourt, Castillo-Chavez, Kaiser, Wojick

8. Metadata Is a Must (when it comes to numeric data)  Numeric databases and other non-text databases must have metadata to enable searchability and retrieval  Numeric databases must have a steward and be consistent with the proven model of text data centers  Holders of numeric data must be encouraged to harmonize practices Promoting access, preservation and interoperability

9.  In cooperation with several World Data Centers, TIB has assigned DOIs for scientific primary data.  Over 400,000 data sets in the field of earth science have been registered; goal is to have a worldwide DOI registration agency for primary data.  The TIB assigns DOIs only for "collections," large data sets, and databases. It does not attempt to treat each data file individually. Ensuring Access to Numeric Data A DOI registry is one approach An example: German National Library for Science and Technology (TIB)

10.  Defense Technical Information Center (Department of Defense)  Office of Research and Development & Office of Environmental Information (Environmental Protection Agency)  Government Printing Office  NASA Scientific and Technical Information Program  National Agricultural Library (Department of Agriculture)  National Archives and Records Administration  National Library of Education (Department of Education)  National Library of Medicine (Department of Heath and Human Services)  National Science Foundation  National Technical Information Service (Department of Commerce)  Office of Scientific and Technical Information (Department of Energy)  USGS/Biological Resources Discipline (Department of Interior) Management of Scientific Text Is a Model for Numeric Data Each agency has an organization to manage STI (Numeric data would need specialist administrator, or steward) The senior STI managers from 12 U.S. federal agencies form an interagency working group called CENDI.

11. Textual Research Results Are Available Through Interagency Portal Provides access to 50 million pages of science information in a single query www.science.gov A parallel approach could be developed for numeric data

12. Establishing Ground Rules for Metadata Enables Access to Data Overcome barriers of organizations

13. Search for Nano Should Reach Text and Numeric Data

14. Data Preservation Dilemma Many critical science and official collections must be sustained for the foreseeable future Critical collections: –Community reference data collections (e.g. Protein Data Bank) –Irreplaceable collections (ARM data related to climate change) –Experimental research data (BaBar/other event data) “…the progress of science and useful arts … depends on the reliable preservation of knowledge and information for generations to come.” “Preserving Our Digital Heritage” Library of Congress NSB raises the right questions No plan for preservation (i.e., no steward) often means that data is lost or damaged

15. In Summary: Three Points on Nano Info Diffusion  Modeling – it’s possible  Metadata – numeric data, unlike textual data, requires metadata to ensure access  Stewardship – numeric data could follow model of textual STI management
