“…The first set was composed of 4426 LOM instances corresponding to an equal number of PDF Learning Objects provided in 135 courses in Electrical Engineering and Computer Science at the MIT Open Courseware site. These metadata have been manually generated by expert catalogers in the MIT OCW team [24]. The metadata downloading was performed on January 12nd 2008.…”

Due to recent developments in automatic metadata generation and interoperability between digital repositories, the production of metadata is now vastly surpassing manual quality control capabilities. Abandoning quality control altogether is problematic, because low quality metadata compromise the effectiveness of services that repositories provide to their users. To address this problem, we present a set of scalable quality metrics for metadata based on the Bruce & Hillman framework for metadata quality control. We perform three experiments to evaluate our metrics: 1) the degree of correlation between the metrics and manual quality reviews, 2) the discriminatory power between metadata sets and 3) the usefulness of the metrics as low quality filters. Through statistical analysis, we found that several metrics, especially Text Information Content, correlate well with human evaluation and that the average of all the metrics are roughly as effective as people to flag low quality instances. The implications of this finding are discussed. Finally, we propose possible applications of the metrics to improve tools for the administration of digital repositories.

“…IMS-CP is in use in various projects (Australian Flexible Learning Framework, 2004a, b, c;Coalition for Networked Information, 2003, p19), and is recognised as the learning community's alternative to METS and MPEG-21 (Coalition for Networked Information, 2003;Ockerbloom et al, 2004). SCORM (Advanced Distributed Learning, 2004), another learning community solution also based on IMS specifications (Coalition for Networked Information, 2003) is also in use (Lubas, 2004). However, by the time it was identified as a possible candidate, it had already been agreed that the proposed future MoPark connection with the learning community was a relatively weak one and that there was no need to assess SCORM as one of the options.…”

Purpose -To report on initial work carried out on a Metadata Options Appraisal undertaken for the Loch Lomond and Trossachs National Park in the context of plans to create and manage complex digital objects called Interpretive Journeys, PDA-based multimedia guides to Park tours. Design/methodology/approach -After some initial work, a phased approach was adopted. In Phase I (reported here), metadata schema for managing structurally complex digital objects were researched to provide a range of appropriate options. Their characteristics were then matched against the Park's general requirements as determined through discussions with staff and an examination of relevant documentation. Findings -It was determined that the METS metadata schema met Park requirements for managing Interpretive Journeys at a general level and could be used both, to inform the development of the planned Digital Asset Management System (an early priority), and to act as the main basis of a framework for determining a detailed metadata solution for the Park. Research limitations/implications -Further work is required in Phase II to determine the detailed metadata requirement for the Park. Practical implications -A useful guide to dealing with a range of management and metadata issues associated with managing complex digital objects, and to managing projects where guidance on metadata requirements is needed before the objects to be described are available. Originality/value -This paper offers an introduction to the management and metadata issues raised by Interpretive Journeys and digital composites of similar complexity, and an indication of how METS addresses these at a general level.

Purpose In the absence of a working model for describing, managing and archiving the human library resources, this study aims to attempt a practical approach that will provide all the necessary information to the library users, library professionals and researchers. Design/methodology/approach Initially, different metadata standards, archival projects and attributes of the human books were reviewed to identify appropriate metadata standards that accurately describe the resources of the human library. A free and open-source software; DSpace was considered for implementing newly defined metadata schema in this study. Thereafter, a set of new subject entries was incorporated to standardize the contents of the human library. Findings This study finds that the widely used metadata schema – Dublin Core (DC) is not appropriate to describe the contents of the human book. It shows that selected metadata elements from the types – person and event of schema.org can be used for describing, organizing and archiving the resources of the human library. It further highlights that existing subject entries are not sufficient to standardize the contents of these types of resources. Research limitations/implications Two metadata fields in DSpace are strongly recommended by the DSpace community to consider in the input-forms.xml file, that is why the study could not completely omit DC metadata elements in describing human books. Originality/value The study provides a roadmap to the library professionals on the inclusion of new metadata schemas in describing the uniquely featured resources of the library.
