The Potential for Web Services to Enhance Information Access to Legacy Data: An Exploratory Study and Application
Paper discussing the potential for web services to enhance information access to legacy data. Abstract: This paper presents an overview of an exploratory research project to identify, describe, and investigate the applicability of the Web services (WS) approach to access legacy data. In the Z Texas Implementation Component of the Library of Texas (ZLOT) project, the ZLOT technical team has implemented a multi-purpose Texas Library Directory Database (TLDD) that is used as a back-end database to support the Library of Texas (LOT) Resource Discovery Service (RDS). The researchers developed and implemented a prototype WS application to show how a legacy system can be accessed and its data can be searched and retrieved. This study focused on understanding how requests and responses between software applications are encoded in Extensible Markup Language (XML). digital.library.unt.edu/ark:/67531/metadc36314/
Improving Z39.50 Interoperability: Z39.50 Profiles and Testbeds for Library Applications
This paper discusses Z39.50 interoperability. Abstract: An operating assumption for the networked environment is that many different information systems need to interoperate for users to successfully discover and retrieve distributed resources. Meaningful interoperability is often elusive. In the library community, the Z39.50 standard protocol (ISO 23950/ANSI/NISO Z39.50) for information retrieval promised seamless and transparent networked access to library resources. Too often, the reality has not lived up to the promise. This paper discusses two efforts that offer solution paths to Z39.50 interoperability. digital.library.unt.edu/ark:/67531/metadc36283/

Assessing Metadata Utilization: An Analysis of MARC Content Designation Use
This paper discusses metadata utilization. Abstract: Metadata schemes emerge to meet community and user requirements, and they evolve over time to meet changing requirements. This paper reports results of an analysis of a large sample of MARC 21 bibliographic records. MARC 21 is an encoding scheme related closely to metadata elements occurring in library bibliographic records. The records were analyzed for the utilization of content designation available in MARC 21. Results indicate that less than 5% of available content designation accounts for over 80% of occurrences. The implications of these findings affect indexing policies, system design, and can inform setting requirements for extending a metadata scheme based on a threshold of community requirements. digital.library.unt.edu/ark:/67531/metadc36303/

High-Throughput Workflow for Computer-Assisted Human Parsing of Biological Specimen Label Data
This grant proposal is for the United States Institute of Museum and Library Services National Leadership Grant. Abstract: The University of North Texas's Texas Center for Digital Knowledge (TxCDK) and the Botanical Research Institute of Texas (BRIT) will conduct fundamental research with the goal of identifying how human intelligence can be combined with machine processes for effective and efficient transformation of textual museum specimen label information into high-quality machine-processible parsed data. This two-year project will advance understanding of the workflow and processes best able to increase access to and use of digitized biological collection metadata within the stakeholder communities comprised of biologists, natural history museum collections managers, biodiversity standards groups, and the library and information science community. A key challenge faced by all natural history collections is determining a transformation process that yields high-quality results in a cost- and time-efficient manner. The results of this research will yield a new workflow model for effective and efficient label data transformation, correction, and enhancement that can be replicated, adapted, and transferred to herbaria and other natural history collections. digital.library.unt.edu/ark:/67531/metadc81387/

A Study of State Library Agencies' Information Technology Standards Policies and Practices
This report was commissioned and supported by the National Information Standards Organization (NISO). The dynamic pace of technology change challenges all organizations to identify and select standards on which to base mission-critical programs and services. State library agencies face particular challenges because of the increasing demands that publicly supported libraries provide access to increasing quantities and varieties of networked, digital and paper-based information resources and services. State library agencies are in a unique position to influence the adoption and implementation of standards to support statewide library resource sharing. This study, undertaken in 1998, attempted to bridge the gap of information and understanding about the current situation of state library agencies' use, opportunities and issues related to technical standards. digital.library.unt.edu/ark:/67531/metadc102301/
Assessing Interoperability in the Networked Environment: Standards, Evaluation, and Testbeds in the Context of Z39.50
This book chapter discusses interoperability in the networked environment. An underlying assumption of any network is that various components and processes will work together to produce desired results (e.g., data transmission, data interchange, reliability of services, etc.). The term interoperability has been used to characterize this working together, especially, the workings of lower level data communication components. Usage of the term has evolved to refer more generally to the extent to which different types of computers, networks, operating systems, and applications work together effectively to exchange information in a useful and meaningful manner. Miller (2000) suggests a perspective That is even more encompassing: he says that to be interoperable means "one should actively be engaged in the ongoing process of ensuring that the systems, procedures and culture of an organisation are managed in such a way as to maximize opportunities for exchange and re-use of information, whether internally or externally." digital.library.unt.edu/ark:/67531/metadc102281/
