Search Interoperability, OAI, and Metadata: Handout for METRO Workshop

Handout for the workshop on the OAI Protocol for Metadata Harvesting given for METRO on December 8, 2006

Dublin Core Metadata Harvested Through OAI-PMH

The introduction in 2001 of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) increased interest in and awareness of metadata quality issues relevant to digital library interoperability and the use of harvested metadata to build "union catalogs" of digital information resources. Practitioners have offered wide-ranging advice to metadata authors and have suggested metrics useful for measuring the quality of shareable metadata. Is there evidence of changes in metadata practice in response to such advice and/or as a result of an increased awareness of the importance of metadata interoperability? This paper looks at metadata records created over a six-year period that have been harvested by the University of Illinois at Urbana Champaign, and reports on quantitative and qualitative analyses of changes observed over time in shareable metadata quality.IMLS National Leadership Grant LG-02-02-0281published or submitted for publicationis peer reviewe

Towards an architecture for open archive networks in Agricultural Sciences and Technology

The AGRIS Network is an international initiative based on a collaborative network of institutions, whose aim is to promote free access to information on science and technology in agriculture and related subjects. The paper illustrates how the Open Access (OA) and the Open Archive Initiative (OAI) models can be used within the AGRIS Network as a means of solving the problems of dissemination and exchange of agricultural research outputs. The lack of adequate information exchange possibilities between researchers in agricultural sciences and technology represents a significant weakness limiting their ability to properly address the issues of agricultural development. The OA model promotes the dissemination of research output at international, national and regional levels thus removing the restrictions placed by the traditional scientific publishing model. This paper presents the possibility to address the accessibility, availability and interoperability issues of exchanging agricultural research output

Metadata Augmentation for Semantic- and Context- Based Retrieval of Digital Cultural Objects

Cultural objects are increasingly stored and generated in digital form, yet effective methods for their indexing and retrieval still remain an open area of research. The main problem arises from the disconnection between the content-based indexing approach used by computer scientists and the description-based approach used by information scientists. There is also a lack of representational schemes that allow the alignment of the semantics and context with keywords and low-level features that can be automatically extracted from the content of these cultural objects. This paper presents an integrated approach to address these problems, taking advantage of both computer science and information science approaches. The focus is on the rationale and conceptual design of the system and its various components. In particular, we discuss techniques for augmenting commonly used metadata with visual features and domain knowledge to generate high-level abstract metadata which in turn can be used for semantic and context-based indexing and retrieval. We use a sample collection of Vietnamese traditional woodcuts to demonstrate the usefulness of this approach

Application Profile Development for Consortial Digital Libraries: An OhioLINK Case Study

In 2002, OhioLINK’s consortia of libraries recognized the need to restructure and standardize the metadata used in the OhioLINK Digital Media Center as a step in the development of a general purpose digital object re-pository. The authors explore the concept of digital object repositories and mechanisms used to develop complex data structures in a cooperative environment, report the findings and recommendations of the OhioLINK Data-base Management and Standards Committee (DMSC) Metadata Task Force, and identify lessons learned, ad-dressing data structures as well as data content standards. A significant result of the work was the creation of the OhioLINK Digital Media Center (DMC) Metadata Application Profile and the implementation of a core set of metadata elements and Dublin Core Metadata Element Set mappings for use in OhioLINK digital projects. The profile and core set of metatadata elements are described

DRIVER Technology Watch Report

This report is part of the Discovery Workpackage (WP4) and is the third report out of four deliverables. The objective of this report is to give an overview of the latest technical developments in the world of digital repositories, digital libraries and beyond, in order to serve as theoretical and practical input for the technical DRIVER developments, especially those focused on enhanced publications. This report consists of two main parts, one part focuses on interoperability standards for enhanced publications, the other part consists of three subchapters, which give a landscape picture of current and surfacing technologies and communities crucial to DRIVER. These three subchapters contain the GRID, CRIS and LTP communities and technologies. Every chapter contains a theoretical explanation, followed by case studies and the outcomes and opportunities for DRIVER in this field

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
