How to submit
DRUM accepts a wide variety of research materials from all disciplines. There are a small number of conditions:
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.
Preparing data for submission
The submission process has two steps:
We can provide advice and assistance at any stage. If you would like to submit a complex research study with multiple data files and supporting documents, we can help you prepare your materials and organize your submission. Email us in advance.
Get your permanent DOI
After we review your submission, you will receive an email that contains a link to your materials and your DOI. You can use the DOI in publications and wherever you refer to the materials.
Recommendations for specific materials
1. Papers, articles, pre-prints, reports, posters, slides
Submit PDF rather than Word or PowerPoint documents. Other suitable formats include LaTex, OpenDocument formats (odt, odp), plain text (txt), rich text (rtf), and HTML.
If you plan to submit a paper that has been published or presented elsewhere, please have the citation information ready.
Submit comma-separated, tab-separated, or other delimited or fixed-width files for tabular or 'ascii' data (e.g. txt, csv, tab, tsv). Excel and Access files are acceptable, but avoid submitting data in specialized instrument formats. See our file format recommendations for additional suggestions.
Data should be accompanied by a 'readme' file, data dictionary, codebook, or similar document that contains, where applicable:
Submit code files with the appropriate language extension (e.g. mat, py, r, pl, f). Software should be accompanied by a 'readme' file that contains, where applicable:
4. Images, audio, and video
For image files, submit JPEG, TIFF, PNG, PDF, or SVG. For audio or video file, submit MPEG (mp3, mp4), WAV, AVI, or Quicktime (mov). Other formats are acceptable, but they may be less useful to other researchers.
Images, audio, and video should be accompanied by a 'readme' file or similar document that contains any of the items listed for data (above) that apply to your material.
5. Everything else
DRUM can accept 3D models, biological and chemical sequences, geospatial data, text corpora, and many other research outputs. We can help you select file formats, prepare documentation, and organize your submission.
Consider including a 'readme' file or similar document that contains any of the items listed for data (above) that apply to your material.
