A bibliographic metadata infrastructure for the twenty-first century

The current library bibliographic infrastructure was constructed in the early days of computers – before the Web, XML, and a variety of other technological advances that now offer new opportunities. General requirements of a modern metadata infrastructure for libraries are identified, including such qualities as versatility, extensibility, granularity, and openness. A new kind of metadata infrastructure is then proposed that exhibits at least some of those qualities. Some key challenges that must be overcome to implement a change of this magnitude are identified

Requirements and services for metadata management

Knowledge-intensive applications pose new challenges to metadata management, including distribution, access control, uniformity of access, and evolution in time. The authors identify general requirements for metadata management and describe a simple model and service that focuses on RDF metadata to address these requirements

Mapping the Metadata challenges in Libraries: A systematic review

Background. In the information and knowledge world, libraries always played their important role and found as early adopters of new techniques and technologies for dissemination of information. Purpose. If we understand the metadata as a researcher’s perspective, it is exploratory in its nature which provides guidance to the further data which is explanatory. There are many metadata challenges which affect the execution and accessibility of relevant data. These challenges must be recognized at one place so that LIS professionals having interest in metadata could be able to understand these challenges and hurdles concerning with libraries. So, this this study is being conducted to find out the challenges of metadata and bring these challenges synthetically from scattered literature for the readers. Design/methodology/approach. To compete this study, a systematic literature review approach has been followed. Thirteen paper are selected to find out the challenges faced by the libraries concerning with the metadata. Findings. In this systematic review 85 challenges were found from the scholarly published literature which are categorized into 19 categories according to their nature and likeliness. Further, general challenges and project based challenges are presented separately. Practical implications. Through this study scattered challenges of metadata faced by the libraries are grouped together to strengthen the lacking information. This paper will add knowledge in the existing literature in form of comprehensiveness

Provenance in Linked Data Integration

The open world of the (Semantic) Web is a global information space offering diverse materials of disparate qualities, and the opportunity to re-use, aggregate, and integrate these materials in novel ways. The advent of Linked Data brings the potential to expose data on the Web, creating new challenges for data consumers who want to integrate these data. One challenge is the ability, for users, to elicit the reliability and/or the accuracy of the data they come across. In this paper, we describe a light-weight provenance extension for the voiD vocabulary that allows data publishers to add provenance metadata to their datasets. These provenance metadata can be queried by consumers and used as contextual information for integration and inter-operation of information resources on the Semantic Web

From Dublin Core to MARC - Crosswalking ETD Metadata from Digital Commons to the Library Catalog

Florida International University has developed a semi-automated process for harvesting and transforming qualified Dublin Core metadata to MARC for electronic theses and dissertations published in Digital Commons for inclusion in the library catalog. This presentation will share the workflow whereby metadata is harvested via OAI-PMH; transformed to MARC using a script; and ingested into the catalog. Challenges and benefits of this workflow will be discussed. This presentation will also share information related to our retrospective thesis and dissertation scanning project; the need to overlay existing records in the catalog with new metadata; and specific challenges related to RTDs

Finding the right rabbit to pull out of the hat: data management in CSIRO

CSIRO is one of the world’s largest and most diverse research agencies with staff located literally from one end of Australia to the other as well as internationally. As both a creator and a consumer of research data, CSIRO faces considerable data management challenges. To this end, the development of the CSIRO Data Management Service (DMS) Repository is a pivotal step in the right direction for managing CSIRO-generated data, third-party data and establishing vital links with research community portals such as Research Data Australia and the Atlas of Living Australia. From metadata mapping to collector and conversion tools, this presentation will discuss the experiences of the CSIRO Information Management & Technology (IM&T) team in applying new services and technologies to address the challenges of discovering, exchanging and re-using research data

Query management in a sensor environment

Traditional sensor network deployments consisted of fixed infrastructures and were relatively small in size. More and more, we see the deployment of ad-hoc sensor networks with heterogeneous devices on a larger scale, posing new challenges for device management and query processing. In this paper, we present our design and prototype implementation of XSense, an architecture supporting metadata and query services for an underlying large scale dynamic P2P sensor network. We cluster sensor devices into manageable groupings to optimise the query process and automatically locate appropriate clusters based on keyword abstraction from queries. We present experimental analysis to show the benefits of our approach and demonstrate improved query performance and scalability

Ready or not here it comes: Australian institutional research repository data readiness surveys 2010

Australian institutional research repositories are now facing a new challenge: datasets and associated metadata. With prior focus predominantly on research outputs, repository managers are now involved in a new phase of repository re-purposing - curation of datasets and associated metadata, and provision of this metadata to a national data commons through ANDS (Australian National Data Service). Through a series of surveys conducted by the national repository support service, CAIRSS (the CAUL Australian Institutional Repository Support Service), this paper examines the research data challenges facing research repository managers, levels of institutional research data identification, and the readiness of traditional institutional research repositories to either curate or work alongside this data

Harvesting community tags and annotations to augment institutional repository metadata

One of the greatest challenges facing managers of institutional repositories today is the cost of providing high quality, precise metadata that satisfies the search requirements of their many different user groups. Social tagging systems such as Flickr, del.icio.us, Connotea and You.tube enable communities to tag photos, web pages, scientific publications and videos with organically-evolved, community relevant vocabularies and to share their tags through the Web. But is there a way that repository managers can exploit these new community tagging movements to enhance their collections’ metadata? If users are provided with simple tagging services, can they be encouraged to generate meaningful, useful metadata that can then be harvested and exploited? This presentation will describe a number of semantic tagging and annotation services that we have developed for open repositories of social sciences and humanities data (indigenous collections, linguistic recordings, publications). It will also discuss possible solutions to the associated social and technical challenges that include: motivating users to attach annotations; ensuring quality control and authentication of the annotations; techniques for harvesting meaningful useful metadata (using OAI PMH); exploiting the secondary metadata to improve the search and browse capabilities over the repositories; differentiating between primary and secondary metadata in the presentation of search results
