The paper “Metadata Quality for Biobankshas been published in applied sciences on the 23th of September 2022 and is available as free full-text on the link over it.

Abstract

The mission of biobanks is to provide biological material and data for medical research. Reproducible medical studies of high quality require material and data with established quality. Metadata, defined as data that provides information about other data, represents the content of biobank collections, particularly which data accompanies the stored samples and which quality the available data features. The quality of biobank metadata themselves, however, is currently neither properly defined nor investigated in depth. We list the properties of biobanks that are most important for metadata quality management and emphasize both the role of biobanks as data brokers, which are responsible not for the quality of the data itself but for the quality of its representation, and the importance of supporting the search for biobank collections when the sample data is not accessible. Based on an intensive review of metadata definitions and definitions of quality characteristics, we establish clear definitions of metadata quality attributes and their metrics in a design science approach. In particular, we discuss the quality measures accuracy, completeness, coverage, consistency, timeliness, provenance, reliability, accessibility, and conformance to expectations together with their respective metrics. These definitions are intended as a foundation for establishing metadata quality management systems for biobanks.

Abstract

Time and cost are crucial criteria in Service Level Agreements. Frequently, the time when and how long a service can be provided or used and the cost for utilizing a service are related and hence users are confronted with a trade-off between time and cost. Besides the fundamental direct and indirect proportional relationship between time and cost, composed services might also have more complex non-monotonic relationships. We introduce a novel way of expressing the trade-offs between time and cost in form of TC-Maps as a set of piece-wise linear functions. For calculating the duration, cost and their relation for service compositions, we introduce specific operations used in a bottom-up procedure resulting in an overall TC-Map. The proposed structure allows us to derive the minimum cost of a composed service given a duration limit, or for analyzing possible durations for a provided budget. TC-Maps offer the basis for optimizing the utilization of composed services according to user preferences, resources and objectives.
