Abstract

Definition of a conceptual reference model to provide a framework for the analysis of non-administrative metadata relating to library resources. The resulting model definition was approved by the FRBR Review Group (November 2016), and then made available to the Standing Committees of the Sections on Cataloguing and Subject Analysis & Access, as well as to the ISBD Review Group, for comment in December 2016. The final document was approved by the IFLACommittee on Standards (August 2017).

Abstract

Aggregates have been a frequent topic of discussion between library science researchers. This study seeks to better understand aggregates through the analysis of a sample of bibliographic records and review of the cataloging treatment of aggregates. The study focuses on determining how common aggregates are in library collections, what types of aggregates exist, how aggregates are described in bibliographic records, and the criteria for identifying aggregates from the information in bibliographic records. A sample of bibliographic records representing textual resources was taken from OCLC's WorldCat database. More than 20 percent of the sampled records represented aggregates and more works were embodied in aggregates than were embodied in single work manifestations. A variety of issues, including cataloging practices and the varying definitions of aggregates, made it difficult to accurately identify and quantify the presence of aggregates using only the information from bibliographic records.

Abstract

The Functional Requirements for Subject Authority Records (FRSAR) Working Group was formed in 2005 as the third IFLA working group of the FRBR family to address subject authority data issues and to investigate the direct and indirect uses of subject authority data by a wide range of users. This paper introduces the Functional Requirements for Subject Authority Data (FRSAD), the model developed by the FRSAR Working Group, and discusses it in the context of other related conceptual models defined in the specifications during recent years, including the British Standard BS8723-5: Structured vocabularies for information retrieval - Guide Part 5: Exchange formats and protocols for interoperability, W3C's SKOS Simple Knowledge Organization System Reference, and OWL Web Ontology Language Reference. These models enable the consideration of the functions of subject authority data and concept schemes at a higher level that is independent of any implementation, system, or specific context, while allowing us to focus on the semantics, structures, and interoperability of subject authority data.

Abstract

In 1998, the FRBR model (Functional Requirements for Bibliographic Records) was developed under the auspices of the International Federation of Library Associations and Institutions (IFLA). The library domain finally developed its conceptual model of the bibliographic universe and thus the basis for the development of novel bibliographic information systems. In 2017, the IFLA Library Reference Model (Riva, LeBoeuf and Zumer 2017) was formally accepted as an IFLA standard. The FRBR family of models as well as LRM all start from the user tasks that need to be enabled and supported by bibliographic information systems. The consolidation process included a detailed analysis of all entities, attributes and relationships defined by the FRBR family. In this paper, the main features of the model are presented and described. With IFLA LRM, we finally have a modern model, compatible with the semantic web.

Abstract

Continuing the tradition set by the FRBR model, a new IFLA working group was formed to examine the functional requirements for subject authority records (FRSAR). The focus of the FRSAR Working Group is on the user tasks and functional requirements of authority records for the Group 3 entities as defined by FRBR. This paper presents the Working Group's terms of reference and reports on initial activities and subject authority issues discussed.

Abstract

Integrating resources are distinct in that they change over time in such a way that their previous content is replaced with updated content. This study examines how integrating resources can be modeled using the entities and relationships of the IFLA Library Reference Model (LRM) and clarifies how they can be identified. While monographs have been extensively analyzed, integrating resources have received very little attention. Applying the model unmodified to integrating resources is neither practical nor theoretically sound. With the addition of two proposed relationships, the model can be extended to accommodate the diachronic relationship intrinsic between expressions and manifestations exhibited by integrating resources.

Abstract

Scientific enterprise represents a pivotal area in knowledge organization because of its prolific use of emerging information technology and its close network of researchers in government, industry, and universities as producers and consumers of knowledge. The ALCOM/NIST Heterogeneous Structures Database (http://cpip.kent.edu/PSP) is an online information system involving university research scientists, government agencies, and industrial partners in the ALCOM/NIST Heterogeneous Structures Project. The Database is the first stage of a multiphase knowledge base of liquid crystal science, the Basic and Applied Liquid Crystal Research Database. This paper will describe the system functionality of the Heterogeneous Structures Database and the expansion of a previously existing tool, the Thesaurus for Liquid Crystal Research and Applications (http://www.personal.kent.edu/~slis/zeng/maja2.html), into the Database. The first part of the paper will discuss how the design of the Database addresses the following user characteristics from multidisciplines involved in the project: interdisciplinarity, basic and applied research, experts and novices users, and user population groups (academia, government, and industry). The second part of the paper will report on how the authors are developing a frame of knowledge structure to meet these characteristics

Abstract

The FR family of conceptual models has grown to include three separate models prepared independently over many years by different working groups: FRBR for bibliographic data, FRAD for authority data, and FRSAD for subject authority data. Even as FRAD and FRSAD were being finalized in 2009-2010, it became clear that it would be necessary to combine or consolidate the FR family into a single coherent model to clarify the understanding of the overall model and remove barriers to its adoption. The FRBR Review Group has been working towards this since 2011, constituting a Consolidation Editorial Group in 2013. The consolidation task involves not only spelling out how the three existing models fit together, but requires taking a fresh look at the models to incorporate insights gained since their initial publications. This paper, based directly on the work of the Consolidation Editorial Group, provides the first public report of the consolidated model, tentatively referred to as the FRBR-Library Reference Model (FRBR-LRM), and the guiding principles that have been applied in its development.

Abstract

This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

Abstract

Purpose - Aims to present a comparison and evaluation of four user interfaces of web-based e-journals (Science Direct, ProQuest Direct, EBSCO Host and Emerald). Design/methodology/approach - The systems were assessed in an expert study according to accepted guidelines regarding user friendliness and functionality. User friendliness features studied were: language(s) and type(s) of interface; navigation options; personalization; and screen features. Functions inspected were: database selection; query formulation and reformulation; results manipulation; and help. Findings - Many similarities were found, but some differences among the systems were also discovered and analysed in detail. The greatest differences were found in the area of query formulation, and between the interface languages and types. Research limitations/implications - The user interfaces of four full-text IR systems offering e-journals which are accessible at the University of Ljubljana are surveyed. Practical implications - The interfaces are surveyed and assessed in order to discover their characteristics, advantages, and potential downsides and/or mistakes which may hinder use by an average user. Originality/value - The study serves as a basis for a subsequent user study of the information behaviour of the users of these systems.

Abstract

The IFLA study Functional requirements for bibliographic records (FRBR) set a new frame for both cataloguing codes and subject analysis. The Paris Principles defined the functions of the catalogue followed by both cataloguing codes used in Slovenia: P. Kalan's Abecedni imenski katalog and E. Verona's Pravilnik i prirunik za izradbe abecednih kataloga. FRBR defines the functions for records themselves, irrespective of the type of the database consisting of these records. Compared to the requirements for the national bibliographic records as defined by FRBR, the records belonging to the Slovenian national bibliography show more descriptive elements and less notes on bibliographic history, which reflects in lack of uniform titles. As the uniform title itself enables the identification of related works and their expressions, this practice does not satisfy the FRBR requirements. Differences in the extent of records for different types of material derive from decentralised processing at the National and University Library. It is therefore necessary to establish uniform criteria for both the materials included into the Slovenian national bibliography, and the extent of data elements.
