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.

File sizes

You can upload multiple files with each submission, but for technical reasons the submission form will not accept individual files over 2GB. You can submit zipped, tarred, or other archive files.

If you have individual files larger than 2GB, we will load them into DRUM for you. Email us to get started.

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 applicable:

  • 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

Boilerplate text for data management plans

For the section of your plan that addresses data access and sharing:

Data 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 librarians work with researchers to select and implement platform-independent file formats (e.g. csv, txt) for long-term access.

For the section of your plan that addresses long-term preservation:

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. DRUM conforms to the digital preservation principles outlined in the University of Maryland Libraries’ Digital Preservation Policy.
