Access Interfaces for Open Archival Information Systems based on the OAI-PMH and the OpenURL Framework for Context-Sensitive Services
In recent years, a variety of digital repository and archival systems have
been developed and adopted. All of these systems aim at hosting a variety of
compound digital assets and at providing tools for storing, managing and
accessing those assets. This paper will focus on the definition of common and
standardized access interfaces that could be deployed across such diverse
digital respository and archival systems. The proposed interfaces are based on
the two formal specifications that have recently emerged from the Digital
Library community: The Open Archive Initiative Protocol for Metadata Harvesting
(OAI-PMH) and the NISO OpenURL Framework for Context-Sensitive Services
(OpenURL Standard). As will be described, the former allows for the retrieval
of batches of XML-based representations of digital assets, while the latter
facilitates the retrieval of disseminations of a specific digital asset or of
one or more of its constituents. The core properties of the proposed interfaces
are explained in terms of the Reference Model for an Open Archival Information
System (OAIS).Comment: Accepted paper for PV 2005 "Ensuring Long-term Preservation and

Building Digital Libraries from Simple Building Blocks
Metadata harvesting has been established by the Open Archives Initiative (OAI) as a
viable mechanism for connecting a provider of data to a purveyor of services. The Open
Digital Library (ODL) model is an emerging framework which attempts to break up the
services into appropriate components based also on the basic philosophy of the OAI
model. This framework has been applied to various projects and evaluated for its
simplicity, extensibility and reusability to support the hypothesis that digital libraries
(DLs) should be built from simple Web Service-like components instead of as monolithic
software applications
Creating a national federation of archives using OAI-PMH
This paper describes the planning stages of the creation of a national level federation of archives. The Open Archives Initiative Protocol for Metadata Harvesting will be used for collecting metadata being produced by local archives using any compliant records management software. The first stage of implementation will harvest metadata produced with the DigitArq [1-3] platform in a pilot group of Portuguese Regional Archives. DigitArq relies on Encoded Archival Description (EAD) metadata to describe its collections. However, the overwhelming flexibility and complexity of EAD make the harvesting operation more complex than usual. This paper addresses possible ways of exchanging EAD records using OAI-PMH as the basis for a central repository of metadata that will enable the creation of advanced information services at the national level
BlogForever D3.2: Interoperability Prospects
This report evaluates the interoperability prospects of the BlogForever platform. Therefore, existing interoperability models are reviewed, a Delphi study to identify crucial aspects for the interoperability of web archives and digital libraries is conducted, technical interoperability standards and protocols are reviewed regarding their relevance for BlogForever, a simple approach to consider interoperability in specific usage scenarios is proposed, and a tangible approach to develop a succession plan that would allow a reliable transfer of content from the current digital archive to other digital repositories is presented
Getting Indexed by Bibliographic Databases in the Area of Computer Science
Every author and publisher is interested in adding their publications to the widely used bibliographic databases freely accessible in the world wide web: This ensures the visibility of their publications and hence of the published research. However, the inclusion requirements of publications in the bibliographic databases are heterogeneous even on the technical side. This survey paper aims in shedding light on the various data formats, protocols and technical requirements of getting indexed by widely used bibliographic databases in the area of computer science and provides hints for maximal database inclusion. Furthermore, we point out the possibilities to utilize the data of bibliographic databases, and describes some personal and institutional research repository systems with special regard to the support of inclusion in bibliographic databases
