Abstract

Information management in corporate environments is a growing problem as companies' information assets grow and their need to use them in their operations. Several management models have been practiced with application on the most diverse fronts, practices that integrate the so-called Enterprise Content Management. This study proposes a conceptual model of semantic corporate information ecosystem, based on the Universal Document Model proposed by Dagobert Soergel. It focuses on unstructured information objects, especially multimedia, increasingly used in corporate environments, adding semantics and expanding their recovery potential in the composition and reuse of dynamic documents on demand. The proposed model considers stable elements in the organizational environment, such as actors, processes, business metadata and information objects, as well as some basic infrastructures of the corporate information environment. The main objective is to establish a conceptual model that adds semantic intelligence to information assets, leveraging pre-existing infrastructure in organizations, integrating and relating objects to other objects, actors and business processes. The approach methodology considered the state of the art of Information Organization, Representation and Retrieval, Organizational Content Management and Semantic Web technologies, in the scientific literature, as bases for the establishment of an integrative conceptual model. Therefore, the research will be qualitative and exploratory. The predicted steps of the model are: Environment, Data Type and Source Definition, Data Distillation, Metadata Enrichment, and Storage. As a result, in theoretical terms the extended model allows to process heterogeneous and unstructured data according to the established cut-outs and through the processes listed above, allowing value creation in the composition of dynamic information objects, with semantic aggregations to metadata.

Abstract

Based on the concept of an application profile as proposed by the Dublin Core initiative, the work presented in this manuscript attempts to propose an application profile for the Earth Observation images. This approach aims to provide an open and extensible model facilitating the sharing and management of distributed images within decentralized architectures. It is intended to eventually cover the needs of discovery, localization, consulting, preservation and processing of data for decision support. We are using the Singapore framework recommendations to build the application profile. A particular focus on the formalization and representation of Description Set Profile (DSP) in RDF is proposed.

Abstract

In diesem Artikel beschreiben wir die Implementierung eines Klassifikationsservers für Metadatenorganisation in einem Langzeitarchivierungssystem für digitale Objekte. Nach einer kurzen Einführung in Klassifikationen und Wissensorganisationen stellen wir die Anforderungen an das zu implementierende System vor. Wir beschreiben sämtliche Simple Knowledge Organization System (SKOS) Management Tools, die wir untersucht haben, darunter auch Skosmos, die Lösung, die wir für die Implementierung gewählt haben. Skosmos ist ein open source, webbasierter SKOS Browser, basierend auf dem Jena Fuseki SPARQL Server. Wir diskutieren einige entscheidende Schritte während der Installation der ausgewählten Tools und präsentieren sowohl die potentiell auftretenden Probleme mit den verwendeten Klassifikationen als auch mögliche Lösungen.

Abstract

French law on digital legal deposit covers websites and online content as well as ebooks. It imposes no obligation to produce a bibliography, indexing being sufficient. But despite their innovative characteristics, ebooks are still books, and their metadata is closer to that of printed materials than to the web indexing. To set up an ebook deposit workflow, the BnF benefits from its experience with digital documents and its tradition of legal deposit. This is to present the questions that it faces when dealing with the cataloging of ebooks and the management of their metadata, and the solutions that are emerging.

Abstract

This article presents a case study of quality management issues for electronic resource metadata to assess the support of user tasks (find, select, and obtain library resources) and potential for increased efficiencies in acquisitions and cataloging workflows. The authors evaluated the quality of existing bibliographic records (mostly vendor supplied) for e-resource collections as compared with records for the same collections in OCLC's WorldShare Collection Manager (WCM). Findings are that WCM records better support user tasks by containing more summaries and tables of contents; other checkpoints are largely comparable between the two source record groups. The transition to WCM records is discussed.

Abstract

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

The discovery and retrieval of video games in library and information systems is, by and large, dependent on a limited set of descriptive metadata. Noticeably missing from this metadata are classifications of visual style-despite the overwhelmingly visual nature of most video games and the interest in visual style among video game users. One explanation for this paucity is the difficulty in eliciting consistent judgements about visual style, likely due to subjective interpretations of terminology and a lack of demonstrable testing for coinciding judgements. This study presents a taxonomy of video game visual styles constructed from the findings of a 22-participant cataloging user study of visual styles. A detailed description of the study, and its value and shortcomings, are presented along with reflections about the challenges of cultivating consensus about visual style in video games. The high degree of overall agreement in the user study demonstrates the potential value of a descriptor like visual style and the use of a cataloging study in developing visual style taxonomies. The resulting visual style taxonomy, the methods and analysis described herein may help improve the organization and retrieval of video games and possibly other visual materials like graphic designs, illustrations, and animations.

Abstract

Resource Description & Access (RDA) is intended to provide a flexible and extensible framework that can accommodate all types of content and media within rapidly evolving digital environments while also maintaining compatibility with the Anglo-American Cataloguing Rules, 2nd edition (AACR2). The cataloging community is grappling with practical issues in navigating the transition from AACR2 to RDA; there is a definite need to evaluate major subject areas and broader themes in information organization under the new RDA paradigm. This article aims to accomplish this task through a thorough and critical review of the emerging RDA literature published from 2005 to 2011. The review mostly concerns key areas of difference between RDA and AACR2, the relationship of the new cataloging code to metadata standards, the impact on encoding standards such as Machine-Readable Cataloging (MARC), end user considerations, and practitioners' views on RDA implementation and training. Future research will require more in-depth studies of RDA's expected benefits and the manner in which the new cataloging code will improve resource retrieval and bibliographic control for users and catalogers alike over AACR2. The question as to how the cataloging community can best move forward to the post-AACR2/MARC environment must be addressed carefully so as to chart the future of bibliographic control in the evolving environment of information production, management, and use.
