Metadata are critical in epidemiological and public health research. However,a lack of biomedical metadata quality frameworks and limited awareness of theimplications of poor quality metadata renders data analyses problematic. Inthis study, we created and evaluated a novel framework to assess metadataquality of epidemiological and public health research datasets. We performed aliterature review and surveyed stakeholders to enhance our understanding ofbiomedical metadata quality assessment. The review identified 11 studies andnine quality dimensions; none of which were specifically aimed at biomedicalmetadata. 96 individuals completed the survey; of those who submitted data,most only assessed metadata quality sometimes, and eight did not at all. Ourframework has four sections: a) general information; b) tools and technologies;c) usability; and d) management and curation. We evaluated the framework usingthree test cases and sought expert feedback. The framework can assessbiomedical metadata quality systematically and robustly.
