Dataset search in biodiversity research: Do metadata in data repositories reflect scholarly information needs?

addition, title, rights and descriptions as well as resource type were also provided in more than 99% of the analyzed metadata files. However, in only 45% of the metadata files, keywords (subject) were present. Figshare used only 12 out of 17 available fields of QDC, but these fields were always filled. 5 out of 17 fields of QDC were not used at all. Fig 6. Metadata field usage in all data repositories evaluated. The graphics display the percentage of metadata fields used per data repository and its best matching standard with respect to the information categories. https://doi.org/10.1371/journal.pone.0246099.g006 PLOS ONE Dataset search in biodiversity research PLOS ONE | https://doi.org/10.1371/journal.pone.0246099 March 24, 2021 25 / 36
