rdfs:frbr -Towards an Implementation Model for Library Catalogs Using Semantic Web Technology
2005
The paper sets out from a few basic observations (bibliographic information is still mostly part of the 'hidden Web,' library automation methods still have a low WWW-transparency, and take-up of FRBR has been rather slow) and continues taking a closer look at Semantic Web technology components. This results in a proposal for implementing FRBR as RDF-Schema and of RDF-based library catalogues built on such an approach. The contribution concludes with a discussion of selected strategic benefits resulting from such an approach.
A Model for Digital Libraries and its Translation to RDF
Journal on Data Semantics, 2013
URLs blur access and identification 2 the notion of description of a resource is missing Our model: 1 makes a clear distinction between identification of a resource and access to it 2 provides a way of modeling descriptions as independent resources 3 relates descriptions to the described resources 4 provides a query language for discovering resources based on their descriptions.
Resource Description Framework (RDF)
Encyclopedia of GIS, 2008
The Resource Description Framework (RDF) is the standard knowledge representation language for the Semantic Web, an evolution of the World Wide Web that aims to provide a well-founded infrastructure for publishing, sharing and querying structured data. This article provides an introduction to RDF and its related vocabulary definition language RDF Schema, and explains its relationship with the OWL Web Ontology Language. Finally, it provides an overview of the historical development of RDF and related languages for Web metadata.
The Semantic Portal for Supporting Research Community: a Review
International Journal on Advanced Science, Engineering and Information Technology, 2011
Current state of the art of typical search engines like Google, Yahoo and others are delivering references in terms of web URL or links to the related website. As such the results did not deliver the right answers required to the users needs. In addition to that as soon as the users require a collection of the information obtained, these search engines failed to do so resulting in the human intervention in-combining the information from several sources. Due ot the advancement and the vast number of sites and information on the web, demands in providing higher precision results are required to aid users in obtaining the most relevant result to the search process. One of the promising areas of the Semantic Web is enhancing the query capabilities for information. Small vertical vocabularies and ontologies have emerged, and the community of people using these and generating data is growing daily. However queries or search mechanisms that utilizea the vasrt amount of vocabularies, ontologies and data in digital libraries is still very much lacking. Therefore searching over heteregoneous records, data in digital library community or the Web has become a well known problem to the mass public. As such a solution is needed for a federated search across multiple resources available. However it remains unclear on how Semantic Web or its technology is used in constructing a digital library system or aid in enhancing the quality of the search results performed. This leads to the current work proposed, as work will be conducted to provide possible components that will construct the semantic web portal. The work performed is essential to facilitate semantic searches for research community in large-scale distributed digital library system. The subject research community is chosen particularly to aid in ensuring hat result obtained are accordingly to the users relevant needs. The expected outcomes of the research are an architecture that utilizes the semantic technology that will promote semantic web portal in the digital library and a semantic search mechanism that will provide better results and a combination of useful results relevant to the users.
Exploring Large Document Repositories with RDF Technology: The DOPE Project
IEEE Expert / IEEE Intelligent Systems, 2004
I nnovative research institutes rely on the availability of complete and accurate information about new research and development. Information providers such as Elsevier make it their business to provide the required information in a cost-effective way. The Semantic Web will likely contribute significantly to this effort because it facilitates access to an unprecedented quantity of data. The DOPE project (Drug Ontology Project for Elsevier) explores ways to provide access to multiple lifescience information sources through a single interface.
Adopting RDF at a Large Humanities Digital Library: Lessons From a Challenging Success
Journal of Digital Archives and Digital Humanities, 2023
Resource Description Framework (RDF) is a data technology designed for deep interconnections between projects and appears to be a perfect fit for digital humanities (DH). It is also very challenging to build a robust architecture around it, and this difficulty is an obstacle to its adoption, ultimately hindering interconnections between projects. This article presents the experience of adopting RDF as the native data format at the Buddhist Digital Resource Center (BDRC), and the conventions and tools that were used to make this adoption successful. We hope that this account of our experience can be useful for hesitant technical leads and scholars in DH, and that our conventions and tools can be adopted as recipes, so that more projects can adopt RDF at a lower cost.

Linked open data (LOD) is an essential component in semantic web architecture and is becoming increasingly important over time due to its ability to share and re-use structured data which is both human and computer readable over the web. Currently, many libraries, archives, museums etc. are using open source digital library software to manage and preserve their digital collections. They may also intend to publish their e-resources as "Linked Open Datasets" for further usage. LOD enables the libraries or information centers to publish and share the structured metadata that is generated and maintained with their own bibliographic and authority data in such a way that the other libraries and general community across the world can consume, interact, enrich and share. In this context, the key issue is to convert the library bibliographic data which is commonly known as metadata into LOD dataset. The purpose of this paper is to provide a methodology and technical aspects to design and publish a structured LOD dataset of bibliographic information from a digital repository developed with DSpace digital library software so that other libraries can link their repositories with these LOD for providing additional relevant resources to their end-users. The paper shows the process of integration and configuration of Apache Jena Fuseki (a tool for SPARQL Endpoint interface) with DSpace for converting metadata into Resource Description Framework (RDF) triple model and make them available in various RDF formats. It also discusses a model for building a LOD framework to convert and store RDF graph and RDF triple. Finally, it tests the accessibility of the inked open dataset by querying RDF data through a SPARQL endpoint interface.
Building a Semantic Web Digital Library for the Municipality of Milan
… Publishing: Innovation in …, 2009
In the second half of 2007 the Municipality of Milan decided to co-finance a one year project proposed by CILEA (Consorzio Interuniversitario Lombardo per l'Elaborazione Automatica) called "Biblioteca Aperta di Milano" (Milan Open Library) or BAMI, aimed at creating an integrated system to make a set of digitized documents from the cultural institutions of Milan available on the Web. To meet the goals of the project, we adopted Semantic Web standards and technologies to build the knowledge base and used a faceted browser for the user interface. Faceted browsing is an exploration technique for structured data sets based on facet theory which allows users to find information without a-priori knowledge of its schema. To store and provide the visualisation of digital documents we used Co-deX [ml] and AriannaWeb. Regarding the selection of content, we decided to focus mainly on the documents that belong to a specific branch of the city's cultural heritage: those from the 19 th century, giving special attention to musical documents. In this paper we present the methodology and the workflow that led us to build an ontology with the aid of a Scientific committee of librarians and 19 th century music experts. We also illustrate the usage of a dedicated web-based editor that we used to populate the ontology. One of the most important objectives of the project was to overcome the limitations of the search engines traditionally used in the librarian domain (e.g. OPAC) by providing the users with new tools for browsing and analysing cultural knowledge. Thus, the paper also focuses on the BAMI User Interface, which was built by extending and enhancing Longwell, a faceted RDF browser developed by the Massachusetts Institute of Technology. We then describe the complementarity and flow of information between the three applications (Longwell, CodeX[ml] and AriannaWeb). The paper ends with a discussion of 134 some possible evolutions of the project and of the main difficulties we encountered during the development.
