Components of an NSDL Architecture: Technical Scope and Functional Model [PDF]

arXiv, 2002
We describe work leading toward specification of a technical architecture for the National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL). This includes a technical scope and a functional model, with some elaboration on the particularly rich set of library services that NSDL is expected eventually to encompass.

Revealing digital documents. Concealed structures in data [PDF]

Bulletin of IEEE Technical Committee on Digital Libraries, Volume 8, Issue 3, May 2012, 2011
This short paper gives an introduction to a research project to analyze how digital documents are structured and described. Using a phenomenological approach, this research will reveal common patterns that are used in data, independent from the particular technology in which the data is available.
