Making metadata go away: hiding everything but the benefits

Abstract: In this paper, we argue that, in order to facilitate the ubiquitous uptake of metadata, and in order to realize their potential for advanced flexible end user functionalities, the metadata should become more transparent to the end user. We also argue that we are technically capable of realizing this goal, and illustrate the issues involved with some practical examples.

Metadata and data structures for the historical newspaper digital library

Abstract: We examine metadata and data-structure issues for the Historical Newspaper Digital Library. This project proposes to digitize and then do OCR and linguisting processing on several years worth of historical newspapers. Newspapers are very complex information objects so developing a rich description of their content is challenging. In addition to frameworks for the logical structure and physical layout, we propose metadata relevant to the image processing and to the historians who will use this collection. Finally, we consider how the metadata infrastructure might be managed as it evolves with improved text processing capabilities and how an infrastructure might be developed to support a community of users.

Metabolonote: A Wiki-Based Database for Managing Hierarchical Metadata of Metabolome Analyses

Abstract: Metabolomics - technology for comprehensive detection of small molecules in an organism - lags behind the other "omics" in terms of publication and dissemination of experimental data. Among the reasons for this are difficulty precisely recording information about complicated analytical experiments (metadata), existence of various databases with their own metadata descriptions, and low reusability of the published data, resulting in submitters (the researchers who generate the data) being insufficiently motivated. To tackle these issues, we developed Metabolonote, a Semantic MediaWiki-based database designed specifically for managing metabolomic metadata. We also defined a metadata and data description format, called "Togo Metabolome Data" (TogoMD), with an ID system that is required for unique access to each level of the tree-structured metadata such as study purpose, sample, analytical method, and data analysis. Separation of the management of metadata from that of data and permission to attach related information to the metadata provide advantages for submitters, readers, and database developers. The metadata are enriched with information such as links to comparable data, thereby functioning as a hub of related data resources. They also enhance not only readers' understanding and use of data but also submitters' motivation to publish the data. The metadata are computationally shared among other systems via APIs, which facilitate the construction of novel databases by database developers. A permission system that allows publication of immature metadata and feedback from readers also helps submitters to improve their metadata. Hence, this aspect of Metabolonote, as a metadata preparation tool, is complementary to high-quality and persistent data repositories such as MetaboLights. A total of 808 metadata for analyzed data obtained from 35 biological species are published currently. Metabolonote and related tools are available free of cost at http://metabolonote.kazusa.or.jp/.

Metadata for learning materials: an overview of existing standards and current developments

Abstract: This paper provides an overview of specifications and standards for metadata relating to learning materials. It is structured to present first the currently established metadata schemas in use today (specifically the IEEE LOM and Dublin Core metadata), then to examine current developments and activities before looking at what might be the future challenges. The examination of current developments and activities highlights the increasingly recognized importance of metadata schema that describe what have in the past been thought of as secondary aspects of learning materials (for example who uses them and what for), and the importance of alternative approaches to structured metadata for resource description.
