解决硅藻标本数字化中的元数据混乱问题，提升数据可查可用性。
Making Sense of Metadata Mess: Alignment & Risk Assessment for Diatom Data Use Case
- 构建元数据对齐框架，将硅藻数据映射到标准类型。
- 识别数据清洗过程中的风险点，支持更可靠的数据管理。
- 为全球共享数字标本提供技术基础，适合生物信息与数据科学工作者。
生物学家通过研究硅藻评估水体健康状况。硅藻标本传统上保存在模拟载玻片上，单张载玻片可含数千个微小个体。数字化这些藏品带来元数据挑战与机遇。本文报告了针对费城自然科学院硅藻标本馆（Drexel University）数字部分的元数据研究，涵盖三部分内容：1）回顾相关元数据标准及Hammer等人提出的显微镜元数据框架；2）建立当前硅藻元数据属性与标准类型的基准对齐映射；3）分析标准数据整理流程中伴随的元数据风险。该研究是将这些数字载玻片迁移至新系统DataFed以支持全球访问的整体工作的一部分。论文最后总结并讨论下一步方向。
原文摘要 · Abstract (English)
Biologists study Diatoms, a fundamental algae, to assess the health of aquatic systems. Diatom specimens have traditionally been preserved on analog slides, where a single slide can contain thousands of these microscopic organisms. Digitization of these collections presents both metadata challenges and opportunities. This paper reports on metadata research aimed at providing access to a digital portion of the Academy of Natural Sciences' Diatom Herbarium, Drexel University. We report results of a 3-part study covering 1) a review of relevant metadata standards and a microscopy metadata framework shared by Hammer et al., 2) a baseline metadata alignment mapping current diatom metadata properties to standard metadata types, and 3) a metadata risk analysis associated with the course of standard data curation practices. This research is part of an effort involving the transfer of these digital slides to an new system, DataFed, to support global accessible. The final section of this paper includes a conclusion and discusses next steps.
