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
OSTI’s missionTo advance science and sustain
technological creativity by making R&D findings available and useful to DOE
researchers and the American people.
OSTI’s creedKnowledge is contagious – it’s our job to make sure everyone
“catches” it!
OSTI corollary: If the sharing of knowledge – or knowledge diffusion – is accelerated,
scientific progress is accelerated
Science Progresses as Knowledge Is Shared
Diffusion of Feynman Diagrams

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
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)
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)

Textual Research Results Are Available Through Interagency Portal
Provides access to 50 million pages of science information in a single query

A parallel approach could be developed for numeric data

Search for Nano Should Reach Text and Numeric Data
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
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
