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 upload multiple files with each submission, but for technical reasons the submission form will not accept individual files larger than 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. Contact 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 files, associated metadata, and any guidelines for secondary use. All records in DRUM are assigned a persistent URL to support consistent citation. Starting in mid-2014, all new records will be assigned a DOI. The project description will be automatically indexed in Google and Google Scholar to support global discovery.
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. Whenever possible, digital curation librarians work with researchers to select and implement sustainable file formats for long-term preservation.
