Using DRUM to Share and Preserve Data
You can use the Digital Repository at the University of Maryland
(DRUM) to archive, share,
and preserve data associated with a study or project. You can also deposit code,
documents, images, supplemental material, and other research products.
Depositing data in DRUM can help you satisfy data management and sharing
requirements from the NSF, NIH, and other funding agencies and journals.
You can track downloads of your research, and everything in DRUM is
indexed by Google and Google Scholar. You receive a permanent DOI for your
items, making it easy for other researchers to cite your work.
- Please note that DRUM cannot accept confidential or sensitive materials
(e.g. PII, endangered species, ITAR, etc.). De-identified or otherwise redacted
materials are acceptable.
You can upload multiple files with each
submission, but for technical reasons the submission form will not accept
individual files over 2GB. If you have individual files larger than 2GB, we will
load them into DRUM for you. Email us to
You can submit zipped, tarred, or other archive files.
Format and documentation recommendations for data
Submit comma-separated, tab-separated, or other delimited or
fixed-width files for tabular or ‘ASCII’ data (e.g. txt, csv, tab, tsv). Excel,
Access, and MATLAB files are acceptable, but avoid submitting data in
specialized instrument formats. See our file
format recommendations for additional suggestions.
If you are
submitting supplemental materials associated with an article, please include a
citation to the article with your submission. There is a field in the submission
form for this information.
Data should be accompanied by a 'readme' file,
data dictionary, codebook, or similar metadata document that contains, where
- a file manifest describing file names and contents
- state of the data (raw, cleaned, processed, subset, summary)
- instruments and software used to create the data
- processing steps
- explanation of variables, column headers, value codes, flags, etc.
- software required to view or use the data
- licensing and any terms or conditions of use
- funding source and grant number
- contact information
You can find equivalent recommendations for code, images, video, and
the DRUM website.
Boilerplate text for data
1. For the section of your plan that
addresses data access and sharing:
Research products from this
project will be archived at the Digital Repository at the University of Maryland
(DRUM) unless a more appropriate facility can be identified. DRUM is a
long-term, open-access repository managed and maintained by the University of
Maryland Libraries. Researchers and the general public can download data and
code files, associated metadata and documentation, and any guidelines for
re-use. All records in DRUM are assigned a persistent DOI to support consistent
discovery and citation. The project description will be automatically indexed in
Google and Google Scholar to support global discovery. Whenever possible,
digital curation specialists in the University Libraries work with researchers
to document and format materials for long-term access.
2. For the
section of your plan that addresses long-term preservation:
research products archived in DRUM will be available indefinitely. The
University of Maryland Libraries’ DRUM repository is built on DSpace software, a
widely used, reliable digital repository platform. DRUM performs nightly
bit-level integrity tests on all files, and all contents are regularly copied to
back-up storage. DRUM conforms to the digital preservation principles outlined
in the University of Maryland Libraries’ Digital Preservation Policy.
