Abstract

This paper discusses the use of OCLC's Connexion service (formerly CORC) by the Centre for Digital Library Research at the University of Strathclyde, Glasgow, Scotland. The Centre has completed, and is currently engaged in, a number of research projects involving the application of Dublin Core and MARC21 in creating metadata for digital resources; these include projects an the Glasgow Digital Library, East Dunbartonshire local history, and a pilot Scottish Cultural Portal.The Connexion service provides a MARC21-DC converter, and the Centre has been investigating its incorporation in workflows for creating and maintaining digital libraries. This has included the use of databases to store metadata, with subsequent output to Dublin Core and conversion to MARC21.

Abstract

The paper discusses practical methods of apply DDC to digital library services arising from recent technical developments. These include the use of DDC summaries to create hierarchical browsing and tag cloud interfaces, the utility of DDC as a switching language between different subject heading and classification schemes, and the development of terminology servers for interoperability with digital libraries. The focus is on services based in Europe.

Abstract

The publication of library legacy includes publication of structuring vocabularies such as thesauri, classifications, subject headings. Different sources use different vocabularies, different in structure, width, depth and scope, and languages. Federated access to distributed data collections is currently possible if they rely on the same vocabularies. Mapping techniques and standards supporting them (such as SKOS mapping properties, OWL sameAs and equivalentClass) are still largely experimental, even in the linked data land. Libraries use a variety of controlled subject vocabulary and classification schemes to index items in their collections. Although most collections will employ only a single scheme, different schemes may be chosen to index different collections within a library or in separate libraries; schemes are chosen on the basis of language, subject focus (general or specific), granularity (specificity), user expectation, and availability and support (cost, currency, completeness, tools). For example, a typical academic library will operate separate metadata systems for the library's main collections, special collections (e.g. manuscripts, archives, audiovisual), digital collections, and one or more institutional repositories for teaching and research output; each of these systems may employ a different subject vocabulary, with little or no interoperability between terms and concepts. Users expect to have a single point-of-search in resource discovery services focussed on their local institutional collections. Librarians have to use complex and expensive resource discovery platforms to meet user expectations. Library communities continue to develop resource discovery services for consortia with a geographical, subject, sector (public, academic, school, special libraries), and/or domain (libraries, archives, museums) focus. Services are based on distributed searching (e.g. via Z39.50) or metadata aggregations (e.g. OCLC's WorldCat and OAISter). As a result, the number of different subject schemes encountered in such services is increasing. Trans-national consortia (e.g. Europeana) add to the complexity of the environment by including subject vocabularies in multiple languages. Users expect single point-of-search in consortial resource discovery service involving multiple organisations and large-scale metadata aggregations. Users also expect to be able to search for subjects using their own language and terms in an unambiguous, contextualised manner.

Abstract

This paper describes recent initiatives to make standard library metadata models and structures available to the Semantic Web, including IFLA standards such as Functional Requirements for Bibliographic Records (FRBR), Functional Requirements for Authority Data (FRAD), and International Standard Bibliographic Description (ISBD) along with the infrastructure that supports them. The FRBR Review Group is currently developing representations of FRAD and the entityrelationship model of FRBR in resource description framework (RDF) applications, using a combination of RDF, RDF Schema (RDFS), Simple Knowledge Organisation System (SKOS) and Web Ontology Language (OWL), cross-relating both models where appropriate. The ISBD/XML Task Group is investigating the representation of ISBD in RDF. The IFLA Namespaces project is developing an administrative and technical infrastructure to support such initiatives and encourage uptake of standards by other agencies. The paper describes similar initiatives with related external standards such as RDA - resource description and access, REICAT (the new Italian cataloguing rules) and CIDOC Conceptual Reference Model (CRM). The DCMI RDA Task Group is working with the Joint Steering Committee for RDA to develop Semantic Web representations of RDA structural elements, which are aligned with FRBR and FRAD, and controlled metadata content vocabularies. REICAT is also based on FRBR, and an object-oriented version of FRBR has been integrated with CRM, which itself has an RDF representation. CRM was initially based on the metadata needs of the museum community, and is now seeking extension to the archives community with the eventual aim of developing a model common to the main cultural information domains of archives, libraries and museums. The Vocabulary Mapping Framework (VMF) project has developed a Semantic Web tool to automatically generate mappings between metadata models from the information communities, including publishers. The tool is based on several standards, including CRM, FRAD, FRBR, MARC21 and RDA.
The paper discusses the importance of these initiatives in releasing as linked data the very large quantities of rich, professionally-generated metadata stored in formats based on these standards, such as UNIMARC and MARC21, addressing such issues as critical mass for semantic and statistical inferencing, integration with user- and machine-generated metadata, and authenticity, veracity and trust. The paper also discusses related initiatives to release controlled vocabularies, including the Dewey Decimal Classification (DDC), ISBD, Library of Congress Name Authority File (LCNAF), Library of Congress Subject Headings (LCSH), Rameau (French subject headings), Universal Decimal Classification (UDC), and the Virtual International Authority File (VIAF) as linked data. Finally, the paper discusses the potential collective impact of these initiatives on metadata workflows and management systems.

Abstract

RDA has always been a continually evolving standard that aims to reflect the requirements of the cataloguing community. Simon Edwards will highlight the steps towards a further internationalisation and exploration of wider cultural heritage description communities. Gordon Dunsire will point out the potential implementations of RDA data in various database structures and describes the possibilities for further work with RDA and linked data scenarios in international communities. The third part of the article reflects the experience of the British Library in applying RDA in the last years. Alan Danskin gives an overview of the transition period from the project organization until training.

Abstract

Presents an overview of cataloguing and indexing activities taking place in Scotland. Outlines the background to the current cataloguing scene by describing the work of SCOLCAP (Scottish Libraries Cooperative Automation Project) during the 970s and 1980s, and the activities of the Library's Association's Cataloguing and Indexing Group in Scotland, founded in 983. Scotland now dhas a well established infrastructure of professional information organizations including the Scottish Confederation of University and Research Libraries and the Scottish Library and Information Council. Describes 4 current cataloguing and indexing projects: SALSER (Scottish Academic Serials); CATRIONA (Cataloguing and Retrieval of Information Over Network Access); SLAINTE (Scottish Libraries across the Internet); and BOSLIT (Bibliography of Scottish Literature in Translation). Proposes 3 important future developments: a distributed catalogue of research and educational materials held in the libraries of Scotland; an effective mechanism for the storage and preservation of electronic information objects of national significance; and a standard, integrated catalogue or index of all local history resources

Abstract

The focus of this paper is the provision of terminology- and classification-based terminologies interoperability data via web services, initially using interoperability data based on the use of a Dewey Decimal Classification (DDC) spine, but with an aim to explore other possibilities in time, including the use of other spines. The High-Level Thesaurus Project (HILT) Phase IV developed pilot web services based on SRW/U, SOAP, and SKOS to deliver machine-readable terminology and crossterminology mappings data likely to be useful to information services wishing to enhance their subject search or browse services. It also developed an associated toolkit to help information services technical staff to embed HILT-related functionality within service interfaces. Several UK information services have created illustrative user interface enhancements using HILT functionality and these will demonstrate what is possible. HILT currently has the following subject schemes mounted and available: DDC, CAB, GCMD, HASSET, IPSV, LCSH, MeSH, NMR, SCAS, UNESCO, and AAT. It also has high level mappings between some of these schemes and DDC and some deeper pilot mappings available.

Abstract

The mission of the W3C Library Linked Data Incubator Group, chartered from May 2010 through August 2011, has been "to help increase global interoperability of library data on the Web, by bringing together people involved in Semantic Web activities - focusing on Linked Data - in the library community and beyond, building on existing initiatives, and identifying collaboration tracks for the future." In Linked Data [LINKEDDATA], data is expressed using standards such as Resource Description Framework (RDF) [RDF], which specifies relationships between things, and Uniform Resource Identifiers (URIs, or "Web addresses") [URI]. This final report of the Incubator Group examines how Semantic Web standards and Linked Data principles can be used to make the valuable information assets that library create and curate - resources such as bibliographic data, authorities, and concept schemes - more visible and re-usable outside of their original library context on the wider Web. The Incubator Group began by eliciting reports on relevant activities from parties ranging from small, independent projects to national library initiatives (see the separate report, Library Linked Data Incubator Group: Use Cases) [USECASE]. These use cases provided the starting point for the work summarized in the report: an analysis of the benefits of library Linked Data, a discussion of current issues with regard to traditional library data, existing library Linked Data initiatives, and legal rights over library data; and recommendations for next steps. The report also summarizes the results of a survey of current Linked Data technologies and an inventory of library Linked Data resources available today (see also the more detailed report, Library Linked Data Incubator Group: Datasets, Value Vocabularies, and Metadata Element Sets) [VOCABDATASET].
Key recommendations of the report are: - That library leaders identify sets of data as possible candidates for early exposure as Linked Data and foster a discussion about Open Data and rights; - That library standards bodies increase library participation in Semantic Web standardization, develop library data standards that are compatible with Linked Data, and disseminate best-practice design patterns tailored to library Linked Data; - That data and systems designers design enhanced user services based on Linked Data capabilities, create URIs for the items in library datasets, develop policies for managing RDF vocabularies and their URIs, and express library data by re-using or mapping to existing Linked Data vocabularies; - That librarians and archivists preserve Linked Data element sets and value vocabularies and apply library experience in curation and long-term preservation to Linked Data datasets.

Abstract

This paper describes the basic concepts of terminology services and their role in information retrieval interfaces. Terminology services are consumed by other software applications using machine-to-machine protocols, rather than directly by end-users. An example of a terminology service is the pilot developed by the High Level Thesaurus (HILT) project which has successfully demonstrated its potential for enhancing subject retrieval in operational services. Examples of enhancements in three such services are given. The paper discusses the future development of terminology services in relation to the Semantic Web.

Abstract

New technologies will underpin the future generation of library catalogues. To facilitate their role providing information, serving users, and fulfilling their mission as cultural heritage and memory institutions, libraries must take a technological leap; their standards and services must be transformed to those of the Semantic Web. Bibliographic Information Organization in the Semantic Web explores the technologies that may power future library catalogues, and argues the necessity of such a leap. The text introduces international bibliographic standards and models, and fundamental concepts in their representation in the context of the Semantic Web. Subsequent chapters cover bibliographic information organization, linked open data, methodologies for publishing library metadata, discussion of the wider environment (museum, archival and publishing communities) and users, followed by a conclusion.

Abstract

Paper presented at the Library Association 'Under 1 umbrella 2' Conference, Manchester, Jul 93. Computers are good at flexible data storage and distribution, data manipulation and transfromation, and rules. These abilities give rise to a couple areas of general functionality which are of use to cataloguers: integration of cataloguing tools, and intelligent assistance. Cataloguers are good at suggesting structures for organizing and managing information in a consistent way, understanding the problems of human language and providing useful interfaces between the general enquirer and the answer. Discusses the concept of virtual reality and what it can do for the user but warns that it cannot be effectively implemented without the appropriate combination of information technology and information management skills

Abstract

The article discusses the use of International Standard for Bibliographic Description (ISBD) in linked data application profiles and mappings to other bibliographic element sets including UNIMARC (UNIversal MARC), MARC 21, and Resource Description and Access (RDA), establishing ISBD's support for hierarchical relationships between fine-grained properties for resource attributes and coarser-grained aggregations for end-user displays of data triples, and interoperability of metadata derived from different schema. Separation of ISBD punctuation from element properties allows its use in text-based displays while accommodating innovative ways of presenting record-level sets of linked data. The article concludes with a discussion of the issues facing ISBD in maintaining a role in the future library linked data environment.

Abstract

The article is an updated and expanded version of a paper presented to International Federation of Library Associations and Institutions in 2013. It describes recent work involving the representation of International Standard for Bibliographic Description (ISBD) and UNIMARC (UNIversal MARC) in Resource Description Framework (RDF), the basis of the Semantic Web and linked data. The UNIMARC Bibliographic format is used to illustrate issues arising from the development of a bibliographic element set and its semantic alignment with ISBD. The article discusses the use of such alignments in the automated processing of linked data for interoperability, using examples from ISBD, UNIMARC, and Resource Description and Access.

Abstract

This article presents a case study of RIMMF, a software tool developed to improve the orientation and training of catalogers who use Resource Description and Access (RDA) to maintain bibliographic data. The cataloging guidance and instructions of RDA are based on the Functional Requirements conceptual models that are now consolidated in the IFLA Library Reference Model, but many catalogers are applying RDA in systems that have evolved from inventory and text-processing applications developed from older metadata paradigms. The article describes how RIMMF interacts with the RDA Toolkit and RDA Registry to offer cataloger-friendly multilingual data input and editing interfaces.

Abstract

This paper describes recent work on registering Resource Description Framework (RDF) versions of the entities and relationships from the Functional Requirements for Bibliographic Records (FRBR) and Functional Requirements for Authority Data (FRAD) models developed by the International Federation of Library Associations and Institutions (IFLA). FRBR was developed several years before FRAD, and is under-developed in areas which FRAD was expected to cover; FRAD therefore makes significance reference to FRBR. Similarly, FRAD leaves a full treatment of subject authority data to the ongoing development of Functional Requirements for Subject Authority Data (FRSAD) which was finalised during 2010. Although the FRBR Review Group is charged with consolidating all three models in due course, the RDF versions of FRBR, FRAD, and FRSAD are being created in separate namespaces, with a separate Web Ontology Language (OWL) ontology to connect the three models. The paper discusses interoperability issues arising from this work. Such issues include class definitions and sub-classes, reciprocal properties, and disjoint classes and properties. The paper discusses similar work on the International Standard Bibliographic Description (ISBD), also maintained by IFLA, and related issues arising from the RDF representation of the metadata element set of RDA: resource description and access, which is based on the FRBR and FRAD models. The work is ongoing, and the paper updates the original conference presentation to the end of October 2010.
