Prepare Your Data
Data Format & Deposit Size
Deep Blue Data will accept any file format. We will accept compressed data (.zip, .gz, tar.gz) although to facilitate basic preservation services compressed data is discouraged. Review file formats and levels of preservation.
We do not foresee placing cumulative storage limits on deposits, but there are some constraints on the size of deposits:
- The maximum size of a deposit uploaded through the online interface is 2 GB.
- For deposits exceeding 2 GB, we will work with depositors to ingest your data. Please contact us if your deposit exceeds 2 GB.
Depositors will be asked to apply one of several Creative Commons licenses to the data. Depositors authorize the Library to distribute the data under the terms of the license they have selected.
We require descriptive metadata for each deposited dataset. A detailed description of the data's origins, purpose, and use are essential for both discoverability and reuse. The following are our minimum requirements:
- Title: a descriptive title for the data and any associated works you deposit along with it
- Authors(s): those involved in creating the data. Enter last name then first name then middle initial. (Ex. Smith, Jane M.)
- Date Coverage: The specific date (ex. mm/dd/yyyy) or span of time (ex. mm/dd/yyyy or mm/dd/yyyy - mm/dd/yyyy) the data set was collected, or relates to, as determined by its author(s).
- Method: a description of how the data set was generated, acquired and/or processed (this should include any software, instrumentation or equipment used.)
- Description: a brief description of the datafiles, what they contain and any accompanying documentation.
The system also generates metadata automatically to help us maintain the integrity of your files and provide a complete record:
- Timestamp: Deep Blue Data captures the time and date of your deposit and generates a timestamp when any changes to deposits are made to track modifications over time.
- Depositor: who made the deposit and any subsequent changes, in case we need to consult with them about issues that arise
- Checksums: an error detection mechanism to help ensure the integrity of the files
Regardless of which license a depositor chooses for data distribution, metadata will always be distributed with the CC0 license in order to facilitate the broadest possible use.
Please see the Guide to Creating Metadata for Your Dataset in Deep Blue Data for more information.
DocumentationEach data set deposited into Deep Blue Data should contain sufficient documentation for people to understand and make use of the data. Please review our Guide to Creating Documentation for Your Data Set in Deep Blue Data for details.
