Manifesting Large and Bulk File Data Publications– Now A Reality!

The Dash team is excited to announce our June feature release: Large and Bulk File upload. Taking into consideration the need for large size and file numbers of datasets, as well as the practicality of server timeouts, we have developed a new feature that allows for up to 1,000 files or 100gb* of data to be published per DOI.

To accomplish this we are using a “manifest” workflow- which means that instead of uploading data directly from your computer, you may enter URLS for where your data are located (on a server or public site) for upload. Once uploaded, Dash will display the data in the same manner as direct upload. To reflect this new option for upload we have updated the Upload page to choose between uploading locally (from your computer) or via a server. Information about file size limits (2gb/file, 10gb total local or 1000 files any size up to 100gb*) are listed on this landing page.

Step 1: Enter URLs where data are located

Step 2: Validated files will appear in Uploaded Files table with any other data files associated from current or former versions

The benefit of using this workflow is that as a user you do not have to watch your screen for many hours as the data upload and instead your data will be uploaded in the back-end, without the involvement of your computer. This upload mechanism is also not limited to large file use- it can be an easy way to transfer your data directly from a server regardless of size.

A complication with this process is that you cannot upload local data and server-hosted data in the same version. Though this seems tricky- we would like to remind you that Dash supports versioning and after successful publication of the server uploaded data you could go back in and add local files (or vice versa).

While at the moment we do not allow for upload from Gdrive, Box, or Dropbox, we are investigating the sharing links necessary for integrating uploads from the cloud. If you have any feedback to make this feature, or any features more accessible or valuable for researchers please do get in touch. Happy Data Publishing!

Note: To utilize this feature and publish your datasets, your data will need to be hosted on a server. Many institutions, departments, and labs have servers used to host data and information (good examples across the UC campuses, MIT, University of Iowa, etc…). If you have any questions about servers on your campus or external resources, please utilize your campus librarians

*Size limits vary per institutional tenant- please check in with your UC Data Librarians if you have any questions
