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

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

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

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

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.

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

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

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

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.

  • 2003
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

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

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

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

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

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.

Breaking the metadata generation bottleneck: preliminary findings

The goal of our 18 month NSDL-funded project is to develop Natural Language Processing and Machine Learning technology which will accomplish automatic metadata generation for individual educational

The Handle System

The Handle System is a general-purpose distributed information system used to assign, manage, and resolve persistent identifiers, known as "handles", for digital objects and other resources on the

Interoperability for digital libraries worldwide

Discusses the history and current directions of interoperability in different parts of computing systems relevant to Digital Libraries

Lightweight Directory Access Protocol

This protocol is specifically targeted at simple management applications and browser applications that provide simple read/write interactive access to the X.500 Directory and is intended to be a complement to the DAP itself.

Kerberos: An Authentication Service for Open Network Systems

An overview of the Kerberos authentication model as imple- mented for MIT's Project Athena is given, which describes the protocols used by clients, servers, and Kerbero to achieve authentication.
