The purpose of this paper is to propose a modification of the Functional Requirements for Authority Data (FRAD) model to accommodate names in non-Roman languages with diverse writing systems.

The model modifies and clarifies the attributes and relationships regarding non-Roman languages of the current FRAD model, based on the definitions of transliteration, transcription, and Romanization in ISO 5127:2001. The modified model overcomes the problems inherent in the current FRAD model when handling writing systems in non-Roman languages.

The proposed model clearly shows the hierarchy of Controlled Access Points (CAPs). CAPs are either based directly on names or derived from other CAPs. For name or person identification, a CAP and its derivations should be treated as a set. The proposed model also resolves ambiguity in the definition of the word transliteration in the current FRAD model.

By establishing new relationships and amending the attributes of the FRAD model, the proposed model better expresses personal names in non-Roman languages as well as names in western languages. It also organizes complex writing systems of non-Roman languages. The proposed model could lead to an improved format for authority data and will facilitate international sharing of data.

The purpose of this paper is to present functional requirements for bibliographic records (FRBR)‐based model and functional requirements for authority data (FRAD)‐based model; both of which incorporate an event concept that transforms FRBR and FRAD with minimal modification.

Relationships between the entities defined in FRBR/FRAD are transformed into event entities and relationships with other kinds of entities. The cardinality of those relationships is also examined. In addition, a comparison of the proposed FRBR‐based model with the object‐oriented FRBR (FRBR_OO) is conducted.

In the proposed event‐aware FRBR model, an event and its output resource are dependent on each other and necessary information about an event can be expressed with information about its output resource, and vice versa. Therefore, the usefulness and expressiveness of the proposed model is limited. In the FRBR_OO model, dependency between an event and its output resource is not observed, except in a few cases, since a different resource and event modeling was adopted there. The event‐aware FRAD model proposed is useful – but also the scope of its usefulness limited since dependency between an event and its input/output resource is not observed on some event entities.

The proposed models are meaningful in terms of understanding the basic structure and features of a model that incorporates an event concept. The usefulness and limitation of event modeling have been clarified through such model building. The proposed models provide a stable basis for examining FRBR/FRAD further.

There has been a significant increase in activity over the past few years to integrate library metadata with the Semantic Web. While much of this has involved the development of controlled vocabularies as “linked data”, there have recently been concerted attempts to represent standard library models for bibliographic metadata in forms that are compatible with Semantic Web technologies. This paper aims to give an overview of these initiatives, describing relationships between them in the context of the Semantic Web.

The paper focusses on standards created and maintained by the International Federation of Library Associations and Institutions, including Functional Requirements for Bibliographic Records, Functional Requirements for Authority Data, and International Standard Bibliographic Description. It also covers related standards and models such as RDA – Resource Description and Access, REICAT (the new Italian cataloguing rules) and CIDOC Conceptual Reference Model, and the technical infrastructure for supporting relationships between them, including the RDA/ONIX framework for resource categorization, and Vocabulary Mapping Framework.

The paper discusses the importance of these developments for releasing the rich metadata held by libraries as linked data, addressing semantic and statistical inferencing, integration with user‐ and machine‐generated metadata, and authenticity, veracity and trust. It also discusses the representation of controlled vocabularies, including subject classifications and headings, name authorities, and terminologies for descriptive content, in a multilingual environment.

Finally, the paper discusses the potential collective impact of these initiatives on metadata workflows and management systems.

The paper provides a general review of recent activity for those interested in the development of library standards, the Semantic Web, and universal bibliographic control.

This chapter covers the significant developments in subject access embodied in the Functional Requirements (FR) family of models, particularly the Functional Requirements for Subject Authority Data (FRSAD) model.

A structured literature review was used to track the genesis of FRSAD. It builds on work by Pino Buizza and Mauro Guerrini who outlined a potential subject access model for FRBR. Tom Delsey, the author of Resource Description and Access (RDA), also examined the problem of adding subject access.

FRSAD seemed to generate little comment when it appeared in 2009, despite its subject model which departed from that in previous FR standards. FRSAD proposed a subject model based on “thema” and “nomen,” whereby the former, defined as “any entity used as the subject of a work,” was represented by the latter, defined as “any sign or sequence of signs.” It is suggested in this chapter that the linguistic classification theory underlying the PRECIS Indexing System might provide an alternative model for developing generic subject entities in FRSAD.

The FR family of models underpin RDA, the new cataloguing code intended to replace AACR2.Thus issues with FRSAD, which are still unresolved, continue to affect the new generation of cataloguing rules and their supporting models.

The purpose of this paper is to provide broad overviews of functional requirements for bibliographic records (FRBR) in the context of Chinese machine-readable cataloguing (CMARC). It examines areas of the FRBR model, FRBR system development, FRBR applications and FRBR research.

A Chinese Koha_LibFRBR testbed was set up to develop three activities: building a FRBR application function library called LibFRBR to maintain FRBRized bibliographic records, implementing a mapping algorithm between CMARC/MARC 21 and FRBR, and designing a new generation Chinese FRBR Online Public Access Catalogue (OPAC) user interface.

The pilot system implementation demonstrates a workable process with useful output using both automated means (through a Perl module) and manual means (through a cataloguing interface (CI)). The study shows that existing poor Relator Code system and the maintenance of very little authority data in libraries in Taiwan are disadvantages in utilizing the FRBR model.

The software modules developed by this research have been released in GitHub through Koha-Taiwan distributed with a General Public License for further application within the Koha community.

The concrete research outcomes include: providing workable practices for CMARC coding information in FRBR, developing FRBRization of Chinese Koha library management systems, developing FRBR tools including LibFRBR, an application function library used to convert bibliographic records into FRBRized structures in Koha, and FRBR CI for library cataloguers and providing a preliminary evaluation on the views of library cataloguers and OPAC users.

The purpose of this paper is to validate the usefulness of resource description and access (RDA) from user perspectives by implementing an RDA-based bibliographic retrieval system, and comparing it against two retrieval systems.

Surveys and interviews were conducted to gather responses from 20 subjects who used the systems. Usability was measured according to the following metrics: search usefulness from search process and results; search efficiency, measured in time and the number of steps involved; general satisfaction for search results and process, and for information need; satisfaction for search functionalities, with five sub-measures (usability of functions of search tool, appropriateness of search results, usability of additional information, usability of associative relations, and appropriateness of search categories); and system convenience in terms of understandability and ease.

The survey results indicate that all but the satisfaction for appropriateness of search categories showed significant differences between the systems. The interviews show that the RDA system received from the subjects a more positive evaluation compared to the counterpart systems, in search usefulness, search efficiency, general search satisfaction, satisfaction for search functionalities.

Though a few organizations such as the Library of Congress in the USA have implemented RDA, no such endeavors have been undertaken in the context of Korean bibliography, and especially for the systematic validation of usability of such a system from user perspectives.

This is the first published study that validates the usefulness perceived by users of RDA in the context of Korean bibliography.

This chapter aims to help librarians understand the underlying rationale for Resource Description and Access (RDA) and recognize the great potential of the Semantic Web for libraries.

It explains the linked data model and Semantic Web technologies in basic, informative terms, and describes how the Semantic Web is constructed. Semantic Web standards and technologies are discussed in detail, including URI, RDF, and ontologies. The study also traces the development of RDA and some of the major library Semantic Web projects. The authors explore how RDA shapes bibliographical data and prepares it for linked data in the Semantic Web. In addition, this study examines what libraries in the United States and the rest of the world have achieved in implementing RDA since its release.

RDA is the correct approach libraries should take.

This is the first and only chapter that covers the development of RDA in other countries as well as in the United States. It is highly informative for anyone who wishes to understand the RDA and Semantic Web and their relevance to libraries in a short period of time.

The purpose of this paper is to consider the nature of community information (CI) and proposes a data model, based on the entity-relationship approach adopted in the Functional Requirements for Bibliographic Records (FRBR), which may assist with the development of future metadata standards for CI systems.

The two main data structure standards for CI, namely the element set developed by the Alliance of Information and Referral Systems (AIRS) and the MARC21 Format for CI, are compared by means of a mapping exercise, after which an entity-relationship data model is constructed, at a conceptual level, based on the definitions of CI found in the literature.

The AIRS and MARC21 data structures converge to a fair degree, with MARC21 providing for additional detail in several areas. However, neither structure is systematically and unambiguously defined, suggesting the need for a data model. An entity-relationship data modelling approach, similar to that taken in FRBR, yielded a model that could be used as the basis for future standards development and research. It was found to effectively cover both the AIRS and MARC21 element sets.

No explicit data model exists for CI, and there has been little discussion reported about what data elements are required to support CI seeking.
