- Abstract
- This paper describes metadata development of an application profile for the National Science Digital Library (NSDL) Achievement Standards Network (ASN) in the United States. The ASN is a national repository of machine-readable achievement standards modeled in RDF that shape teaching and learning in the various states. We describe the nature of the ASN metadata and the various uses to which that metadata is applied including the alignment of the standards of one state to those of another and the correlation of those standards to educational resources in support of resource discovery and retrieval.

- Abstract
- States that heterogeneous project groups today may be expected to use the mechanisms of the Web for sharing information. Metadata has been proposed as a mechanism for expressing the semantics of information and, hence, facilitate information retrieval, understanding and use. Presents an approach to sharing information which aims to use a semantic modeling language as the basis for expressing the semantics of information and designing metadata schemes. Functioning on the borderline between human and computer understandability, the modeling language would be able to express the semantics of published Web documents. Reporting on work in progress, presents the overall framework and ideas

- Abstract
- To improve searching, filtering and processing of information on the Web, a common effort is made in the direction of metadata, defined as machine understandable information about Web resources or other things. In particular, the eXtensible Markup Language (XML) aims at providing a common syntax to emerging metadata formats. Proposes the Structured Graph Format (SGF) an XML compliant markup language based on structured graphs, for capturing Web sites' structure. Presents SGMapper, a client-site tool, which aims to facilitate navigation in large Web sites by generating highly interactive site maps using SGF metadata

- Abstract
- Examines techniques that discover features in sets of pre-categorized documents, such that similar documents can be found on the WWW. Examines techniques which will classifiy training examples with high accuracy, then explains why this is not necessarily useful. Describes a method for extracting word clusters from the raw document features. Results show that the clustering technique is successful in discovering word groups in personal Web pages which can be used to find similar information on the WWW

- Abstract
- This article evaluates practices on metadata quality control in digital repositories and collections using an online survey of cataloging and metadata professionals in the United States. The study examines (1) the perceived importance of metadata quality, (2) metadata quality evaluation criteria and issues, and (3) mechanisms for building quality assurance into the metadata creation process. The survey finds wide recognition of the essential role of metadata quality assurance. Accuracy and consistency are prioritized as the main criteria for metadata quality evaluation. Metadata semantics greatly affects consistent and accurate metadata application. Strong awareness of metadata quality correlates with the widespread adoption of various quality control mechanisms, such as staff training, manual review, metadata guidelines, and metadata generation tools. And yet, metadata guidelines are used less frequently as a quality assurance mechanism in digital collections involving multiple institutions.

- Abstract
- Provision of high-quality subject metadata is crucial for organizing adequate subject access to rich content aggregated by digital libraries. A number of large-scale digital libraries worldwide are now generating subject metadata to describe not only individual objects but entire digital collections as an integral whole. However, little research to date has been conducted to empirically evaluate the quality of this collection-level subject metadata. The study presented in this article compares free-text and controlled-vocabulary collection-level subject metadata in three large-scale cultural heritage digital libraries in the United States and the European Union. As revealed by this study, the emerging best practices for creating rich collection-level subject metadata includes describing a collection's subject matter with mutually complementary data values in controlled-vocabulary and free-text subject metadata elements. Three kinds of complementarity were observed in this study: one-way complementarity, two-way complementarity, and multiple complementarity.

- Abstract
- The Early American Cookbooks digital project is a case study in analyzing collections as data using HathiTrust and the HathiTrust Research Center (HTRC) Portal. The purposes of the project are to create a freely available, searchable collection of full-text early American cookbooks within the HathiTrust Digital Library, to offer an overview of the scope and contents of the collection, and to analyze trends and patterns in the metadata and the full text of the collection. The digital project has two basic components: a collection of 1450 full-text cookbooks published in the United States between 1800 and 1920 and a website to present a guide to the collection and the results of the analysis. This article will focus on the workflow for analyzing the metadata and the full-text of the collection. The workflow will cover: 1) creating a searchable public collection of full-text titles within the HathiTrust Digital Library and uploading it to the HTRC Portal, 2) analyzing and visualizing legacy MARC data for the collection using MarcEdit, OpenRefine and Tableau, and 3) using the text analysis tools in the HTRC Portal to look for trends and patterns in the full text of the collection.

- Abstract
- Metadata systems are concerned with the management of data which describes other data (datasets, catalogues, or actual database management systems) and are presently the subject of intensive research. Metadata systems can be used to store richly detailed forms of information, perform seamless wide ranging searches of information distributed across networks, and to integrate information stored in disparate repositories. Describes a model design and methods of implementation derived from the experience of the Leicester University Metadata Project. The approach utilizes the incorporation of semantic metadata in addition to resource metadata, resulting in a generally more powerful system than existing global directory services. Feature of the class of design is flexibility or implementation, with the ability to provide a coherent metadata system functioning above heterogeneous autonomous distributed databases

- Abstract
- Although research and teaching can (and should) be seen as international, there must also be an underlying national focus, based on the structure of higher education in a particular country and a corresponding unique pattern of teaching and research. This column therefore looks at research and teaching in metadata in the UK and Ireland, since I work at Strathclyde University in the UK that teaches and researches metadata. This column illustrates that, indeed, the current state of research and teaching in metadata is currently healthy in the UK and Ireland. There are a variety or research activities related to metadata taking place. These range from metadata for digital preservation through 'mainstream' metadata applications in library and information work to contributing to work an the semantic web itself. Among the leading organisational foci of metadata research in the UK are: - the Metadata Group at UKOLN (formerly the UK Office of Library and Information Networking) at the University of Bath (http://www.ukoln.ac.uk/metadata/) - the Semantic Web Research Group at the Institute for Learning and Research Technology (ILRT) at the University of Bristol (http://www.ilrt.bristol.ac.uk/discovery/) - the Centre for Digital Library Research (CDLR) at the University of Strathclyde (http://cdlr.strath.ac.uk/).

- Abstract
- The information sciences have traditionally been at the center of metadata-focused research. The US National Security Agency (NSA) intelligence documents revealed by Edward Snowden in June of 2013 brought the term "metadata" into the public consciousness. Surprisingly little discussion in the information sciences has since occurred on the nature and importance of metadata within networked communication systems. The collection of digital metadata impacts the ways that people experience social and technical communication. Without such metadata, networked communication cannot exist. The NSA leaks, and numerous recent hacks of corporate and government communications, point to metadata as objects of new scholarly inquiry. If we are to engage in meaningful discussions about our digital traces, or make informed decisions about new policies and technologies, it is essential to develop theoretical and empirical frameworks that account for digital metadata. This opinion paper presents 5 key sociotechnical characteristics of metadata within digital networks that would benefit from stronger engagement by the information sciences.

- Abstract
- Reports the involvement of the Conference of European National Librarians (CENL), and its responsibility both to preserve and to provide access to books and information in an increasingly electronic world. Describes the 2 European Commission programmes, managed by a Forum of 8 national libraries, to serve these ends: CoBRA (Computer and Bibliographic Record Actions), which established 4 task groups to study: improved European bibliographic services; user needs for bibliographic products; networked record distribution and reuse; and promotion of data sharing; and a new programme called CoBRA PLus to continue the work of CoBRA and widen its focus to include collection based services, with emphasis on resource sharing, user needs and the use of communication networks. Notes the 2 main task groups, concerned with: metadata and bibliographic access, and electronic publications and digital resources, including legal deposit and storage. Notes briefly the 8 specific projects ranging from networking name authority files to the development of a new relationship between publishers and national bibliographic agencies for the control of electronic publications

- Abstract
- The German National Library (DNB) is using a clustering technique to aggregate works from the database Culturegraph. Culturegraph collects bibliographic metadata records from all German Regional Library Networks, the Austrian Library Network, and DNB. This stock of about 180 million records serves as the basis for work clustering-the attempt to assemble all manifestations of a work in one cluster. The results of this work clustering are not employed in the display of search results, as other similar approaches successfully do, but for transferring metadata elements among the cluster members. In this paper the transfer of content-descriptive metadata elements such as controlled and uncontrolled index terms and classifications and links to name records in the German Integrated Authority File (GND) are described. In this way, standardization and cross linking can be improved and the richness of metadata description can be enhanced.

- Abstract
- Metadata research has emerged as a discipline cross-cutting many domains, focused on the provision of distributed descriptions (often called annotations) to Web resources or applications. Such associated descriptions are supposed to serve as a foundation for advanced services in many application areas, including search and location, personalization, federation of repositories and automated delivery of information. Indeed, the Semantic Web is in itself a concrete technological framework for ontology-based metadata. For example, Web-based social networking requires metadata describing people and their interrelations, and large databases with biological information use complex and detailed metadata schemas for more precise and informed search strategies. There is a wide diversity in the languages and idioms used for providing meta-descriptions, from simple structured text in metadata schemas to formal annotations using ontologies, and the technologies for storing, sharing and exploiting meta-descriptions are also diverse and evolve rapidly. In addition, there is a proliferation of schemas and standards related to metadata, resulting in a complex and moving technological landscape - hence, the need for specialized knowledge and skills in this area. The Handbook of Metadata, Semantics and Ontologies is intended as an authoritative reference for students, practitioners and researchers, serving as a roadmap for the variety of metadata schemas and ontologies available in a number of key domain areas, including culture, biology, education, healthcare, engineering and library science.
