A Reconsideration of Mapping in a Semantic World
No full textFor much of the past decade, attempts to corral the explosion of new metadata schemas (or formats) have been notably unsuccessful. Concerns about interoperability in this diverse and rapidly changing environment continue, with strategies based on syntactic crosswalks becoming more sophisticated even as the ground beneath library data shifts further towards the Semantic Web. This paper will review the state of the art of traditional crosswalking strategies, examine lessons learned, and suggest how some changes in approach--from record-based to statement-based, and from syntax-based to semantic-based--can make a significant difference in the outcome. The paper will also describe a semantic mapping service now under development
Universal File System Extended Attributes Namespace
No full textThe growing usage of file system extended attributes on many operating systems faces interoperability problems when trying to preserve them across multiple platforms. We propose a generic namespace design and idempotent mapping method to maintain an identical view of the global metadata namespace by each operating system. Additionally, we try to address the API and semantic incompatibilities with a higher level framework
Metadata Provenance: Dublin Core on the Next Level
Get PDFWith this poster, we want to present the current state of the DCMI Metadata Provenance Task Group, which will wrap up its work at the time of DC-2011. The motivation for a Dublin Core extension for metadata provenance is twofold: Firstly, we want to represent existing metadata provenance information in a simple and unified way that is well suited as an application of Dublin Core. Secondly, we want to enable the provision of provenance information for Dublin Core metadata in a Dublin Core compatible way
Semantic Bibliography Based on Ontology and Linked Data
No full textOur project arises from the need for bibliography organization and integration at the National Science and Technology Library (NSTL1) of China. NSTL consists of nine special national libraries serving basic sciences, agricultural sciences, medical sciences and engineering. The union catalog emphasizes on academic resources, including more than 20,000 journals, 100,000 proceedings and 10,000 reports. Traditional bibliography organization methods provide index points and access points based on MARC fields or subfields, but it does not distinguish information objects extracted from bibliography and does not show the hierarchical or related relationships between them. The goal of our project is to identify, describe and organize the characteristics and relationships of all kinds of bibliography objects, so that end users can access and browse them. We focus on the multiplicity of information forms, the variability in information life circle and the complexity of hybrid objects
Free-Text Collection-Level Subject Metadata in Large-Scale Digital Libraries: A Comparative Content Analysis
Get PDFMetadata is central for information organization in digital libraries. A growing number of digital libraries worldwide are now generating metadata to describe not only individual objects but entire digital collections as integral wholes. However, collection-level metadata has not yet been empirically evaluated. This paper reports results of the study that used an in-depth comparative content analysis to assess free-text collection-level subject metadata in three large-scale digital cultural heritage aggregations in the United States and Europe. As observed by this study, the emerging best practices include encoding a variety of information about a digital collection in free-text collection-level Description metadata element. This includes both subject-specific (topical, geographic and temporal coverage, and types/genres of objects in a digital collection) and non-subject-specific information: title, size, provenance, collection development, copyright, audience, navigation and functionality, language of items in a digital collection, frequency of additions, institutions that host a digital collection or contribute to it, funding sources, item creators, importance, uniqueness, and comprehensiveness of a digital collection
Satellites, the Elsevier Format for Ancillary Information to Scientific Journals and Books
No full textElsevier presents the Satellite format -- a linked data compliant data format to capture, store and expose metadata objects using open standards based metadata frameworks e.g. SKOS, DCMI and SWAN. The satellite format allows for an array of configurable features to be defined on a perproject basis to specify the metadata object and its required business usage. A key use case presented in detail is the modeling of tagging information sourced by text mining and content enhancement suppliers to persist scientific document annotation expressed in RDF, linking text strings within the document to concept URIs in scientific vocabularies
Performing Statistical Methods on Linked Data
No full textIn recent years, many government agencies have published statistical information as Linked Open Data (e.g. Eurostat, data.gov.uk). Yet, while there are a number of visualization tools, researchers use data for scientific statistical analysis to answer their research questions. Currently, they have to download the statistical data in a table-based format, in order to use their statistics software, unfortunately losing all the benefits Linked Data provides to them like interlinking with other data sets. In this paper, we present an approach specifically designed to help researchers to perform statistical analysis on Linked Data. By combining distributed sources with SPARQL, we are able to apply simple statistical calculations, such as linear regression and present the results to the user. Results of testing these calculations with heterogeneous data sources expose a wide range of typical issues on data integration which have to be aware of when working with heterogeneous statistical data
Testing Resource Description and Access (RDA) with Dublin Core
No full textResource Description and Access (RDA) is a new standard for describing all types of resources. Columbia University, the University of Chicago, and the University of Illinois at Urbana- Champaign evaluated the guidelines by means of the Dublin Core element set during the U.S. National Libraries RDA Test, held from October to December 2010. This paper speaks to the issues which emerged during the test and what each institution did to address them. Test set-ups employed, and tools used, as well as a selection of problems encountered are described in the following summation of findings
Linked Jazz: An Exploratory Pilot
No full textThis paper reports on a pilot conducted within Linked Jazz, a project that investigates the potential of Linked Open Data (LOD) technology to enhance discovery and visibility of digital cultural heritage materials. The project explores the applicability of the Friend-Of-A-Friend (FOAF) ontology to digital archives of jazz history to expose relationships among musicians and reveal their community¡¯s network. Finding innovative ways of connecting cultural data and making them searchable in an open discovery environment generates unprecedented opportunities to create new meaning and elicit new streams of interpretation. The project consists of multiple phases and is intended to progress in an iterative and experimental way. The first step was to pilot a method to create a dataset of RDF triples representing jazz artists and their social connections
Metadata Aggregation in Historical Engineering Archives: Building an Integrated Metadata Registry
No full textThis communication describes a prototype project completed by a research team of the Universidad Carlos III de Madrid to build an integrated metadata registry (IMR) for historical engineering archives. This registry was developed as part of a project completed for the Ministerio de Fomento of Spain. The proposed solution offers a way to collect and aggregate metadata from a network of archives that hold historical fonds of civil engineering documents. To enable metadata aggregation and ensure metadata compatibility, the archives participating in the network are requested to share authority records encoded according to the definitive version of EAC-CPF and use descriptors from a set of thesauri published by the Spanish Ministry
