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

This report presents the results of desk-top based study of projects and initiatives in the area of linking and mapping subject tools. While its goal is to provide areas of further study for cross-language subject access in the European Library, and specifically the national libraries of the Ten New Member States, it is not restricted to cross-language mappings since some of the tools used to create links across thesauri or subject headings in the same language may also be appropriate for cross-language mapping. Tools reviewed have been selected to represent a variety of approaches (e.g. subject heading to subject heading, thesaurus to thesaurus, classification to subject heading) reflecting the variety of subject access tools in use in the European Library. The results show that there is no single solution that would be appropriate for all libraries but that parts of several initiatives may be applicable on a technical, organisational or content level.

Abstract

The Working group on Guidelines for (electronic) national bibliographies was established in 2004 has started the work with an analysis of users and contexts of use of national bibliographies (NB) in the digital age. National bibliographies are changing dramatically: they include more and more also bibliographic records for digital resources and national bibliographic agencies are increasingly complementing (or even replacing) printed versions of NB with electronic. The guidelines will be soon posted for the world-wide review; this paper gives and overview of the document prepared so far.

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

This proposal presents the methodology of indexing with images suggested by De Brito and Caribé (2015). The imagetic model is used as a compatible mechanism with FRSAD for a global information share and use of subject data, both within the library sector and beyond. The conceptual model of imagetic indexing shows how images are related to topics and 'key-images' are interpreted as nomens to implement the FRSAD model. Indexing with images consists of using images instead of key-words or descriptors, to represent and organize information. Implementing the imaged navigation in OPACs denotes multiple advantages derived from this rethinking the OPAC anew, since we are looking forward to sharing concepts within the subject authority data. Images, carrying linguistic objects, permeate inter-social and cultural concepts. In practice it includes translated metadata, symmetrical multilingual thesaurus, or any traditional indexing tools. iOPAC embodies efforts focused on conceptual levels as expected from librarians. Imaged interfaces are more intuitive since users do not need specific training for information retrieval, offering easier comprehension of indexing codes, larger conceptual portability of descriptors (as images), and a better interoperability between discourse codes and indexing competences affecting positively social and cultural interoperability. The imagetic methodology deploys R&D fields for more suitable interfaces taking into consideration users with specific needs such as deafness and illiteracy. This methodology arouse questions about the paradigms of the primacy of orality in information systems and pave the way to a legitimacy of multiple perspectives in document indexing by suggesting a more universal communication system based on images. Interdisciplinarity in neurosciences, linguistics and information sciences would be desirable competencies for further investigations about he nature of cognitive processes in information organization and classification while developing assistive KOS for individuals with communication problems, such autism and deafness.

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

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

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.
