We describe the core components of the architecture for the (NSDL) National Science, Mathematics, Engineering, and Technology Education Digital Library. Over time the NSDL will include heterogeneous users, content, and services. To accommodate this, a design for a technical and organization infrastructure has been formulated based on the notion of a spectrum of interoperability. This paper describes the first phase of the interoperability infrastructure including the metadata repository, search…

Representing Contextualized Information in the NSDL

TLDR
This new architecture uses Fedora, a tool for representing complex content, data, metadata, web-based services, and semantic relationships, as the basis of an information network overlay (INO).

An information network overlay architecture for the NSDL

TLDR
The underlying data model and implementation of a new architecture for the National Science Digital Library (NSDL) by the Core Integration Team (CI) is described, based on the notion of an information network overlay.

The National Science Digital Library

TLDR
This paper describes the mission, history, and current status of the National Science Digital Library (NSDL), and focuses on the current and near future work of the NSDL Core Integration (CI) service.

A case study in metadata harvesting: the NSDL

TLDR
Despite some teething troubles and the long‐term difficulties of semantic compatibility, the overall conclusion is optimism that the Open Archive Initiative will be a successful part of the NSDL.

Case Studies in the US National Science Digital Library: DL-in-a-Box, CITIDEL, and OCKHAM

  • 2003
TLDR
These parts of NSDL suggest that it is possible for many nations to support teaching and learning with digital libraries, and that it may be time to launch an International Education Digital Library Association.

Research on the Interoperability Architecture of the Digital Library Grid

TLDR
The architecture of the digital library interoperability is put forward based on the Grid technology, and the working process of thedigital library Grid is presented and the high performance OAI federated search service is realized.

A Study on Architecture of Massive Information Management for Digital Library

TLDR
A novel architecture of massive information management for digital library that complies with the architectural framework is designed and the key components and core services are described in detail.

Metadata aggregation and "automated digital libraries": a retrospective on the NSDL experience

TLDR
This paper reports on the implementation of a digital library based on metadata aggregation using Dublin Core and OAI-PMH, and comments on the general cost, the functionality, and the ultimate effectiveness of this architecture.

A system for building expandable digital libraries

    2003 Joint Conference on Digital Libraries, 2003. Proceedings.
  • 2003
TLDR
A digital library service system, OpenDLib, is introduced that has been designed to be highly expandable in terms of content, services and usage.

How to offer more to users

TLDR
The contribution describes a very closely connected project - Register of Fine Art collections and offers some other proposals for the use of such interconnected resources with the aim to offer users more information and also partly reveal them more knowledge which is hidden in these sources.

Components of an NSDL Architecture: Technical Scope and Functional Model

TLDR
This paper presents several high-level elements of that in-progress specification of a technical architecture for the National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL), including a technical scope and a functional model.

Search Middleware and the Simple Digital Library Interoperability Protocol

TLDR
The protocol allows for both stateful and stateless operation, supports multiple query languages, and defines a simple XML-based return format that can be used with CORBA or HTTP.

The open archives initiative: building a low-barrier interoperability framework

TLDR
The recent history of the OAI is described - its origins in promoting E-Prints, the broadening of its focus, the details of its technical standard for metadata harvesting, the applications of this standard, and future plans.

Metadata: the foundations of resource description

TLDR
Fifty-two librarians, archivists, humanities scholars, and geographers, as well as standards makers in the Internet, Z39.50, and Standard Generalized Markup Language (SGML) communities, attended the workshop, seeking to identify the scope of the problem and achieve consensus on a list of metadata elements that would yield simple descriptions of data.
