Expanding the Search for Digital Preservation Solutions
Date: 2009
Creator: Alemneh, Daniel Gelaw
Description: This paper discusses expanding the search for digital preservation solutions. Abstract: This paper will present some preliminary results on factors that affect the adoption of PREMIS in cultural heritage institutions. The study employed a web-based survey to collect data from 123 participants in 20 countries as well as a semi-structured, follow-up telephone interview with a smaller sample of the survey respondents. Roger's diffusion of innovation theory was used as a theoretical framework. The main constructs considered for the study were relative advantage, compatibility, complexity, trialability, observability, and institutional readiness. The study yielded both qualitative and quantitative data, and preliminary analysis showed that all six factors influence the adoption of PREMIS in varying degrees.

Maintaining Quality Metadata: Toward Effective Digital Resource Lifecycle Management
Date: 2008
Creator: Alemneh, Daniel Gelaw
Description: This paper discusses maintaining quality metadata. Quality is a multidimensional concept. The two aspects of digital library data quality are the quality of the data in the objects themselves, and the quality of the metadata associated with the objects. Because poor metadata quality can result in ambiguity, poor recall and inconsistent search results, the existence of robust quality assurance mechanisms is a necessary feature of a well-functioning digital library. Recognizing the strategic benefit of quality metadata as a means of ensuring long term access to its digital resources, the University of North Texas (UNT) Libraries employ a number of metadata quality assurance procedures, tools, and associated quality assurance mechanisms. This paper discusses issues related to digital resources management and describes how UNT approaches metadata quality issues at various levels of the digital resources life cycle.

Metadata Quality: A Phased Approach to Ensuring Long-Term Access to Digital Resources
Date: 2009
Creator: Alemneh, Daniel Gelaw
Description: This paper discusses metadata quality. Maintaining usable digital collections necessitates maintaining high quality metadata about those digital objects. An effective metadata management approach can help institutions improve consistency, clarity of data lineage and relationships so that institutions can better use, reuse, and integrate resources. The metadata quality characteristics depend on various factors, including: type of resources, user perspectives, needs and priorities, which vary across groups of users. The metadata quality issue is particularly acute if there are multiple institutions participating in collaborative digital projects, where a high level of interoperability is an important element. This paper demonstrates metadata quality assurance mechanisms by examining different quality assessment criteria, including metadata record completeness, consistency, accuracy, provenance, conformance to expectations, and other known substantive factors.

Enhancing the Quality of Metadata: Modular Approach to Digital Resource Lifecycle Management
Date: 2007
Creator: Alemneh, Daniel Gelaw & Phillips, Mark Edward
Description: This paper discusses digital resource management. Abstract: Quality is a multidimensional concept. The two aspects of digital library data quality are the quality of the data in the objects themselves, and the quality of the metadata associated with the objects. Maintaining usable and sustainable digital collections necessitates maintaining high quality metadata about those digital objects. The University of North Texas Libraries recognize the strategic benefit of metadata as a means of ensuring long term access to its digital resources. This paper discusses issues related to digital resource management and describes how the University of North Texas Digital Projects Unit approaches metadata quality issues at various levels of the digital resources life cycle. It also suggests a number of metadata quality assurance procedures, tools, and associated quality assurance mechanisms.

The UNTL Metadata Guidelines: [Version-2, 2006]
Date: 2006
Creator: Alemneh, Daniel Gelaw; Belden, Dreanna; Hartman, Cathy Nelson; Phillips, Mark Edward & Reis, Nancy
Description: This paper discusses the The University of North Texas Libraries' (UNTL) metadata guidelines. The UNTL Metadata Initiative progressed on many fronts in 2005 and 2006, including testing and implementation of the UNTL metadata system, on which The Portal to Texas History system is based. As the metadata work group gains practical experience in describing objects with the recommended elements, the UNTL metadata system continues to evolve. This (verson-2) guideline is a product of a series of revision activities. It should be noted that in order to comply with changing internal and external standards and needs, the UNTL metadata creation guideline will remain under continuous review.

Meeting the Demands of Digital Scholarship: Challenges and Opportunities
Date: 2005
Creator: Alemneh, Daniel Gelaw; Hartman, Cathy Nelson & Hastings, Samantha Kelly
Description: This paper discusses meeting the demands of digital scholarship. The synergies of numerous emerging trends such as the development of open standards and open source software, geometric growth of blogs and podcasts, peer-to-peer networking, cross discipline collaborations, etc. provide new directions for scholarship. Likewise, digital libraries and supporting technologies have now matured to the point where their contents are incorporating complex and dynamic resources and services. Powered by network capability and fueled by digital developments, research is becoming more data intensive in almost every discipline. The rapid pace of development poses new threats and problems. Many of these innovations, for example, may have come at the expense of simplicity, sustainability, and other commonly understood applications in the life cycle management of digital resources. Based on the University of North Texas Libraries' "Portal to Texas History" implementation experiences, this paper provides a general overview on the emerging trends and innovative usage of digital library technologies. This paper provides an overall scenario in the areas of aggregating a variety of digital formats; deploying, maintaining, and archiving digital contents; and other innovative uses of digital library technologies.

Targeted Access for Varied Audiences to Integrated, Heterogeneous Digital Information Resources
Date: 2003
Creator: Alemneh, Daniel Gelaw; Hartman, Cathy Nelson & Hastings, Samantha Kelly
Description: This poster presents an overview of the University of North Texas (UNT) Libraries' "Portal to Texas History" project, which aims to integrate and ensure long-term access to large quantities of heterogeneous digital resources from many different institutions. Portals have emerged as an important tool for facilitating single-point-access to digital resources. The UNT Library is undertaking the leadership role by creating the application framework, setting project standards and guidelines, and facilitating collaborative efforts for content building. Also discussed are expanded services for targeted audiences, project approaches to preservation challenges, collaboration benefits, and other issues that emerged in the process of building a platform for the portal system.

Assessment: We know we should do it but does it have to be so difficult?
Date: August 2008
Creator: Byerly, Gayla & Downey, Annie
Description: This paper discusses assessments. Assessment is an essential part of a quality library instruction program. Librarians learn in library school, at conferences, in articles, and on the job that continuous assessment is necessary to ensure instruction is relevant and effective. So why aren't librarians implementing more assessment programs? Teachers of K-12 and college instructors have used assessment for innumerable years to determine if students are learning concepts and meeting objectives. The thought of not using assessment in the classroom is unthinkable for the majority of teachers. As librarians are doing more and more teaching and are considered teaching faculty in many school districts and at many institutions of higher education, it is more important than ever that we implement assessments in library classrooms.
