    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
    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
    Terminology registries (TRs) are a crucial element of the infrastructure required for resource discovery services, digital libraries, Linked Data, and semantic interoperability generally. They can make the content of knowledge organization systems (KOS) available both for human and machine access. The paper describes the attributes and functionality for a TR, based on a review of published literature, existing TRs, and a survey of experts. A domain model based on user tasks is constructed and a set of core metadata elements for use in TRs is proposed. Ideally, the TR should allow searching as well as browsing for a KOS, matching a user's search while also providing information about existing terminology services, accessible to both humans and machines. The issues surrounding metadata for KOS are also discussed, together with the rationale for different aspects and the importance of a core set of KOS metadata for future machine-based access; a possible core set of metadata elements is proposed. This is dealt with in terms of practical experience and in relation to the Dublin Core Application Profile.

    Abstract
    This paper attempts to explore an approach of using an automatic semantic analysis tool to enhance the "subject" access to materials that are not included in the usual library subject cataloging process. Using two research samples the authors analyzed the access points supplied by OpenCalais, a semantic analysis tool. As an aid in understanding how computerized subject analysis might be approached, this paper suggests using the three-layer framework that has been accepted and applied in image analysis, developed by Erwin Panofsky.

    Abstract
    The Functional Requirements for Subject Authority Records Working Group (FRSAR WG) is the third IFLA Working Group of the FRBR family. It was formed in April 2005 and it was charged with the task of developing a conceptual model of FRBR Group 3 entities within the FRBR framework as they relate to the "aboutness" of works. This paper introduces the Functional Requirements for Subject Authority Data (FRSAD), the model developed by the FRSAR WG, and discusses issues raised during the world-wide review.

    Functional Requirements for Bibliographic Records (FRBR) is a relatively new conceptual model of the bibliographic universe. While it is recognized among library experts, there is a considerable lack of user studies. A pilot study, consisting of three different tasks, was conducted to test the instruments for acquiring mental models of the bibliographic universe. Results show that users do not have a consistent mental model of the bibliographic universe and that various techniques used can be useful for acquiring individuals' mental models of the bibliographic universe. Of the three tasks, the one asking people to rank pairs of similar item according to substitutability revealed results that were closest to FRBR, while card sorting and concept mapping exercises failed to provide a single alternative model.

    Abstract
    Purpose - The paper aims to provide some insight into mental models of the bibliographic universe and how they compare with functional requirements for bibliographic records (FRBR) as a conceptual model of the bibliographic universe. Design/methodology/approach - To get a more complete picture of the mental models, different elicitation techniques were used. The three tasks of the paper were: card-sorting, concept mapping and comparison task. The paper deals with comparison task, which consisted of interviews and rankings, and provides a discussion of the results of the paper as a whole. Findings - Results of the ranking part of the comparison task confirm the findings of concept mapping task. In both cases, while there are individual differences between mental models, on average they gravitate towards FRBR. Research limitations/implications - This is a small study and it provides only a glimpse of the implications of using FRBR as a conceptual basis for cataloguing. More FRBR-related user studies are needed, including similar studies on different groups of individuals and different types of materials, as well as practical studies of user needs and user interfaces. Practical implications - The results of this study are the first user-tested indication of the validity of FRBR as a conceptual basis for the future of cataloguing. Originality/value - This is the first published paper of mental models of the bibliographic universe and uses a unique combination of mental model elicitation techniques.

    Abstract
    Purpose - The paper aims to present the results of the first two tasks of a user study looking into mental models of the bibliographic universe and especially their comparison to the Functional Requirements for Bibliographic Records (FRBR) conceptual model, which has not yet been user tested. Design/methodology/approach - The paper employes a combination of techniques for eliciting mental models and consisted of three tasks, two of which, card sorting and concept mapping, are presented herein. Its participants were 30 individuals residing in the general area of Ljubljana, Slovenia. Findings - Cumulative results of concept mapping show a strong resemblance to FRBR. Card sorts did not produce conclusive results. In both tasks, participants paid special attention to the original expression, indicating that a special place for it should be considered. Research limitations/implications - The study was performed using a relatively small sample of participants living in a geographically limited space using relatively straight-forward examples. Practical implications - Some solid evidence is provided for adoption of FRBR as the conceptual basis for cataloguing. Originality/value - This is the first widely published user study of FRBR, applying novel methodological approaches in the field of Library and Information Science.

    Abstract
    Purpose - This paper aims to build on of a previous study of mental models of the bibliographic universe, which found that the Functional Requirements for Bibliographic Records (FRBR) conceptual model is intuitive. Design/methodology/approach - A total of 120 participants were presented with a list of bibliographic entities and six graphs each. They were asked to choose the graph they thought best represented the relationships between entities described. Findings - The graph based on the FRBR model was chosen by more than half of the participants and none of the alternatives stood out. This gives further indication that FRBR is an appropriate model of the bibliographic universe from users' standpoint. Research limitations/implications - The study only looked at the textual part of the bibliographic universe. Further research is needed for other types of materials. Practical implications - This research suggests that there should be a more positive attitude towards implementation of FRBR-based catalogues. Originality/value - This is one of only a handful of user studies relating to FRBR, which looks to be the backbone of catalogues for years to come. As such, the results should be of interest to everybody involved with catalogues, from cataloguers to the end-users.

    Abstract
    The study Functional Requirements for Bibliograpbic Records (FRBR) was commissioned by IFLA and published in 1998. It defines the core functions of a catalogue (and bibliographic records) as a gateway to information. For that purpose an abstract entity-relationship model of a catalogue is proposed. The FRBR model is revolutionary. The (computer) catalogue is not seen as a sequence of bibliographic records and a replica of the traditional card catalogue, but rather as a network of connected entities, enabling the user to perform seamlessly all the necessary functions. So far there has been some theoretical discussion of the model and some limited experiments, but there is a lack of research in how to implement this theoretical model in practice, in new-generation catalogues. In this paper some reactions to the model are analysed. The main focus is an consequences of the model for the OPAC interface design, particularly the searching functionality and display of results.

    Abstract
    In the bibliographic environment, the term aggregate is used to describe a bibliographic entity formed by combining distinct bibliographic units together. Aggregates are a large and growing class of information resources-up to twenty percent of the bibliographic records in OCLC's WorldCat may represent aggregates. The Functional Requirements for Bibliographic Records: Final Report only briefly references aggregates. Difficulties and inconsistencies in the application of the FRBR model to aggregates have been identified as a significant impediment to FRBR implementation. To address the issue, the FRBR Review Group established a Working Group on Aggregates which completed its charge and submitted its final report in 2011. The Working Group proposed that an aggregate be defined as a "manifestation embodying multiple distinct expressions". This paper examines the proposed definition and explores how aggregates can be modeled.

    Abstract
    The Functional Requirements for Subject Authority Data (FRSAD) conceptual model identifies entities, attributes and relationships as they relate to subject authority data. FRSAD includes two main entities, thema (any entity used as a subject of a work) and nomen (any sign or sequence of signs that a thema is known by, referred to, or addressed as). In a given controlled vocabulary and within a domain, a nomen is the appellation of only one thema. The authors consider the question, can the FRSAD conceptual model be extended beyond controlled vocabularies (its original focus) to model classification data? Models that are developed based on the structures and functions of controlled vocabularies (such as thesauri and subject heading systems) often need to be adjusted or extended to accommodate classification systems that have been developed with different focused functions, structures and fundamental theories. The Dewey Decimal Classification (DDC) system is used as a case study to test applicability of the FRSAD model for classification data, and as a springboard for a general discussion of issues related to the use of FRSAD for the representation of classification data.

    Abstract
    In 2008 the FRBR/CRM Harmonisation Working Group has achieved a major milestone: a complete version of the object-oriented definition of FRBR (FRBRoo) was released for comment. After a brief overview of the history and context of the Working Group, this paper focuses on the primary contributions resulting from this work. - FRBRoo is a self-contained document which expresses the concepts of FRBR using the objectoriented methodology and framework of CIDOC CRM. It is an alternative view on library conceptualisation for a different purpose, not a replacement for FRBR. - This 'translation' process presented an opportunity to verify and confirm FRBR's internal consistency. - FRBRoo offers a common view of library and museum documentation as two kinds of information from memory institutions. Such a common view is necessary to provide interoperable information systems for all users interested in accessing common or related content. - The analysis provided an opportunity for mutual enrichment of FRBR and CIDOC CRM. Examples include: - - Addition of the modelling of time and events to FRBR, which can be seen in its application to the publishing process - - Clarification of the manifestation entity - - Explicit modelling of performances and recordings in FRBR - - Adding the work entity to CRM - - Adding the identifier assignment process to CRM. - Producing a formalisation which is more suited for implementation with object-oriented tools, and which facilitates the testing and adoption of FRBR concepts in implementations with different functional specifications and in different environments.

    Abstract
    The Functional Requirements for Subject Authority Data (FRSAD) conceptual model identifies entities, attributes and relationships as they relate to subject authority data. FRSAD includes two main entities, thema (any entity used as a subject of a work) and nomen (any sign or sequence of signs that a thema is known by, referred to, or addressed as). In a given controlled vocabulary and within a domain, a nomen is the appellation of only one thema. The authors consider the question, can the FRSAD conceptual model be extended beyond controlled vocabularies (its original focus) to model classification data? Models that are developed based on the structures and functions of controlled vocabularies (such as thesauri and subject heading systems) often need to be adjusted or extended to accommodate classification systems that have been developed with different focused functions, structures and fundamental theories. The Dewey Decimal Classification (DDC) system is used as a case study to test applicability of the FRSAD model for classification data, and as a springboard for a general discussion of issues related to the use of FRSAD for the representation of classification data.

    Abstract
    The aim of this article is to analyze how catalogers describe publications without cataloging tools in comparison with the current cataloging process. A total of 46 catalogers took part in the first study, a free description of monographic publications, while 30 catalogers performed original cataloging in their actual environment. A combination of observations and think-aloud protocols was used for data gathering in both studies. The focus was on Slovenian catalogers from different types and sizes of libraries. Results revealed both differences and similarities between catalogers' mental models in the respective studies.

    Abstract
    Metadata related to cultural items such as literature, music and movies is a valuable resource that is currently exploited in many applications and services based on semantic web technologies. A vast amount of such information has been created by memory institutions in the last decades using different standard or ad hoc schemas, and a main challenge is to make this legacy data accessible as reusable semantic data. On one hand, this is a syntactic problem that can be solved by transforming to formats that are compatible with the tools and services used for semantic aware services. On the other hand, this is a semantic problem. Simply transforming from one format to another does not automatically enable semantic interoperability and legacy data often needs to be reinterpreted as well as transformed. The conceptual model in the Functional Requirements for Bibliographic Records, initially developed as a conceptual framework for library standards and systems, is a major step towards a shared semantic model of the products of artistic and intellectual endeavor of mankind. The model is generally accepted as sufficiently generic to serve as a conceptual framework for a broad range of cultural heritage metadata. Unfortunately, the existing large body of legacy data makes a transition to this model difficult. For instance, most bibliographic data is still only available in various MARC-based formats which is hard to render into reusable and meaningful semantic data. Making legacy bibliographic data accessible as semantic data is a complex problem that includes interpreting and transforming the information. In this article, we present our work on transforming and enhancing legacy bibliographic information into a representation where the structure and semantics of the FRBR model is explicit.
