Metadata Quality Control in Digital Repositories and Collections: Criteria, Semantics, and Mechanisms

Abstract: This article evaluates practices on metadata quality control in digital repositories and collections using an online survey of cataloging and metadata professionals in the United States. The study examines (1) the perceived importance of metadata quality, (2) metadata quality evaluation criteria and issues, and (3) mechanisms for building quality assurance into the metadata creation process. The survey finds wide recognition of the essential role of metadata quality assurance. Accuracy and consistency are prioritized as the main criteria for metadata quality evaluation. Metadata semantics greatly affects consistent and accurate metadata application. Strong awareness of metadata quality correlates with the widespread adoption of various quality control mechanisms, such as staff training, manual review, metadata guidelines, and metadata generation tools. And yet, metadata guidelines are used less frequently as a quality assurance mechanism in digital collections involving multiple institutions.

Improving metadata quality: augmentation and recombination

Abstract: Digital libraries have, in the main, adopted the traditional library notion of the metadata "record" as the basic unit of management and exchange. Although this simplifies the harvest and re-exposure of metadata, it limits the ability of metadata aggregators to improve the quality of metadata and to share specifics of those improvements with others. The National Science Digital Library (NSDL) is exploring options for augmenting harvested metadata and re-exposing the augmented metadata to downstream users with detailed information on how it was created and by whom. The key to this augmentation process involves changing the basic metadata unit from "record" to "statement."

Set of metadata for association with a composite media item and tool for creating such set of metadata

Abstract: A set of metadata for association with the composite media item and a tool for creating a composite media item with an associated set metadata. In one embodiment, the tool comprises a component for extracting a portion of a first media item having first metadata and for extracting a portion of a second media item having second metadata, a component for combining the first portion and the second portion to form a composite media item, and a component for analyzing the first metadata and the second metadata to extract portions of the first and second metadata to form a new set of metadata for association with the composite media item. In one embodiment, the new metadata is a data container.

Identifying application metadata in a backup stream

Abstract: A method of identifying application metadata in a backup stream comprises finding a known application metadata signature within a backup stream. A source application of user data in the backup stream is identified based upon the known application metadata signature. Application metadata, which has been generated by the source application, is removed from consideration by a data de-duplicator which is used to perform data de-duplication on the backup stream.
