16 · Survey Results: Executive Summary
All of the case study repositories allow authors to
submit descriptive metadata for repository content,
and most of them rely on repository staff and stu-
dent workers to submit descriptive metadata, and/
or enhance or perform quality control of the records.
Eight of the 12 repositories have developed a custom-
ized vocabulary, which can help to document a field
and standardize terminology (see Table 4).
