Integrating Ontology-based Metadata Enrichment into a CMS-based Research Infrastructure
No full textThis abstract discusses research under development aiming to create an ecosystem of entities connected to a research institution, such as its researchers and the resources produced. In particular, we are investigating ways of being able to enter metadata descriptions in a uniform way on the one hand, and to expose them in various different formats on the other. Here, we aim at supporting current standards for metadata exchange, such as the Open Archives Initiative Protocol for Metadata Harvesting, as well as the Resource Description Framework (RDF) in order to be able to interlink the descriptions with others available on the Linking Open Data (LOD) cloud. For the whole process to integrate smoothly into our existing research infrastructure, the approach presented here relies on the Open Source Content Management System Drupal, as it is at the center of our current infrastructure for managing metadata
Metadata-related Challenges for Realizing a Federated Searching System for Japanese Humanities Databases
No full textThis paper provides a summary of our ongoing project for providing integrated access to Japanese multiple digital libraries, archives, and museums. The main goal to construct a federated searching system for Japanese humanities databases, which searches multiple databases in parallel and provides on-the-fly integration of the results, has required the system to deal with heterogeneous metadata schemas in various formats. In this paper we discuss the metadata-related challenges faced at the front-end for retrieving multiple Japanese databases in parallel and integrating bilingual retrieved results. Aggregation and integration of the retrieved results in English and Japanese are complicated if a search needs to be performed from multilingual sources
Establishing a Multi-Thesauri-Scenario based on SKOS and Cross-Concordances
No full textThis case study proposes a scenario with three topic-related thesauri, which have been connected with bilateral cross-concordances as part of a major terminology mapping initiative in the project KoMoHe (Mayr et al., 2008). The thesauri have already been or will be converted to SKOS and in order to not omit the relevant crosswalks, the mapping properties of SKOS will be used for modeling them adequately. The participating thesauri in this approach are: (i) TheSoz (Thesaurus for the Social Sciences, GESIS) which has been converted to SKOS in a first experimental version (Zapilko et al., 2009), an update is underway which will be oriented on the introduced SKOS extensions of the EUROVOC thesaurus (Smedt, 2009) and will use SKOS-XL additionally, (ii) STW (Standard-Thesaurus for Economics, ZBW) which has also been published in SKOS format (Neubert, 2009) and (iii) IBLK-Thesaurus (SWP).
Currently, the conversion of vocabularies to SKOS is an active research area, but there are still unsolved and relevant issues which could not be treated satisfyingly yet. Our approach focuses on the application of existing crosswalks to the SKOS mapping properties and the establishment of a linked data application based on those connected thesauri
Bridging End Users’ Terms and AGROVOC Concept Server Vocabularies
No full textAGROVOC is one of the most important resources for covering the terminology of all subjects to interest the Food and Agriculture Organization of the United Nations (FAO) (including agriculture, forestry, fisheries, food and related domains). AGROVOC is a multilingual thesaurus developed by FAO and the Commission of the European Communities in the early 80s. Since then it has continuously been updated by FAO in collaboration with partner organizations in different countries, and is now available online in 19 languages .
AGROVOC is currently being converted from a traditional term-based knowledge organization system (KOS) to a concept-based system (Soergel, 2004), the AGROVOC Concept Server (CS). The CS allows the representation of more semantics such as specific relationships between concepts as well as relationships between their multilingual lexicalizations. Its functions include being a resource to help structure and standardize agricultural terminology in multiple languages for use by any number of different users and systems around the world. An enabling tool, the AGROVOC Concept Server Workbench (ACSW), has been developed by FAO in collaboration with Kasetsart University in Thailand and other partners. It supports the maintenance of the CS data in a distributed environment (Sini, 2008). One of the goals of the project is to set up a network of international experts who can share the collaborative maintenance and extension of the AGROVOC CS, and thus enhance the creation of agricultural knowledge much more efficiently. The ACSW is part of the larger Agricultural Ontology Service (AOS) initiative and the first major step towards an "Ontology Service" (Fisseha, 2001), which aims to provide semantic-based services to users in the agricultural domain. To cover all agricultural related information, ACSW needs integrated vocabularies
Moving Library Metadata Toward Linked Data: Opportunities Provided by the eXtensible Catalog
No full textTo ensure that they can participate in the Semantic Web, libraries need to prepare their legacy metadata for use as linked data. eXtensible Catalog (XC) software facilitates converting legacy library data into linked data using a platform that enables risk-free experimentation and that can be used to address problems with legacy metadata using batch services. The eXtensible Catalog also provides “lessons learned” regarding the conversion of legacy data to linked data by demonstrating what MARC metadata elements can be transformed to linked data, and helping to suggest priorities for the cleanup and enrichment of legacy data. Converting legacy metadata to linked data will require a team of experts, including MARC-based catalogers, specialists in other metadata schemas, software developers, and Semantic Web experts to design and test normalization/conversion algorithms, develop new schemas, and prepare individual records for automated conversion. Library software applications that do not depend upon linked data may currently have little incentive to enable its use. However, given recent advances in registering legacy library vocabularies, converting national library catalogs to linked data, and the availability of open source software such as XC to convert legacy data to linked data, libraries may soon find it difficult to justify continuing to create metadata that is not linked data compliant. The library community can now begin to propose smart practices for using linked data, and can encourage library system developers to implement linked data. XC is demonstrating that implementing linked data, and converting legacy library data to linked data, are indeed achievable
The One-To-One Principle: Challenges in Current Practice
No full textThe DCMI One-to-One Principle holds that related but conceptually different entities, such as a photograph and a digital image of that photograph, should be represented by separate metadata records. In practice, however, large numbers of practitioners do not adhere to this principle and commonly mix elements representing two related entities in a single metadata record. This paper explores reasons why this is the case, why it is problematic, how the principle itself would benefit from greater clarity, some practical options for maintaining the principle in current systems, with advantages and disadvantages of each. The paper focuses on the widespread application context of small to medium-sized cultural heritage institutions digitizing unique local resources, creating metadata using digital collection software packages such as CONTENTdm, and exposing only simple Dublin Core metadata for OAI harvesting and aggregating
The public library catalogue as a social space: Transaction log analysis of user interaction with social discovery systems.
No full textThe specific goal of this project is to examine and compare how library users access, use, and interact with two social discovery systems used in two Canadian public library systems. Transaction log analysis will be conducted to answer the following research questions: a) How do public library users interact with social discovery systems? Specifically, which enhanced catalogue features do they use, e.g., faceted navigation, user-contributed content such as tagging, reviews, and ratings, sorting features, etc., and with which frequency? b) How does usage between the two social discovery systems compare? Specifically, are there commonalities or differences between how public library users use different social discovery systems? and c) Does the use of social discovery systems change over time? Specifically, is the use of the features in social discovery systems consistent over time
FRBR: A Generalized Approach to Dublin Core Application Profiles
No full textAccording to the Singapore Framework, any development of a Dublin Core Application Profile (DCAP) has to include the creation of a domain model. DC Scholarly Works Application Profile (SWAP) was the first one explicitly using Functional Requirements for Bibliographic Records (FRBR) model in creating its domain model. FRBR has recently been extended with Functional Requirements for Authority Data (FRAD) and Functional Requirement for Subject Authority Data (FRSAD) thus forming the so-called FRBR family. This paper first further develops the SWAP domain model to incorporate the FRBR family models. Then a generalized FRBR-family-based DCAP domain model is presented to be used as the basis for specific domain application profiles
Celebrating 10 Years of Government of Canada Metadata Standards
No full textAs the Dublin Core Metadata Initiative celebrates its 15th anniversary, the Government of Canada (GC) celebrates its 10th year of making information easier to find. The Government of Canada officially adopted the Dublin Core as its core metadata standard for Web resource discovery in 2001. Soon the Government of Canada started to develop domain-specific metadata beyond Web and resource discovery to meet wider information needs. Supported by standards and other policy instruments, rapid metadata developments were made in the areas of records management, Web content management, e-learning, executive correspondence and geospatial data. The Government of Canada has been an active participant in the DC-Government Working Group, and organized its own event, the Canadian Metadata Forum in 2003 and 2005. More recently, the Government of Canada has adopted an enterprise information architecture (EIA) approach to metadata, within a larger information management strategy. The Government of Canada now has plans underway to develop other metadata domains, registries and repositories, its own namespace facility, and a vast awareness campaign to brand metadata as the “DNA of Government”
Building Metadata Application Framework for Chinese Digital Library: A Case Study of National Digital Library of China
No full textThis paper reports a project named “General Rules of National Digital Library Metadata”, trying to build a metadata application framework for National Library of China (NLC). It aims at solving the applications of DC in Chinese digital library, developing a series of related standards, criteria and platform, to meet the requirements of describing, organizing, managing, serving and preserving the Chinese digital objects. It functions to support producing, processing, organizing, releasing, preserving and managing information resources in the digital library system of NLC, and then to achieve the interoperability and data sharing with other digital library systems to the more extent.
The project outcomes are two parts: a metadata application framework and principles of National Digital Library of China based on the work of DCMI and the other international leading metadata projects, and a conversion program. According to this project, we are trying to find the best practice of metadata application for developing digital library in China
