Information for contributors:

  1. Consulting FAIR Principles (guidelines to improve the Findability, Accessibility, Interoperability, and Reuse of digital assets) is often helpful for effective data curation.
  2. Please make sure that the provided links will be long lasting. DOIs or handles can often be obtained through an institutional repository.
  3. Please be thoughtful about selecting licenses for data and code. For the Mechanical MNIST dataset, we chose a Creative Commons Attribution-ShareAlike 4.0 License for the data, and a MIT License for the code (we do not endorse any particular license choice).
  4. Keep file sizes small whenever possible. For example, it may make sense to create a HDF5 file.
  5. For the “Recommended Challenge,” data should be curated so that a user with limited familiarity can download all or part of the dataset and start working on the problem in just a few minutes. Think of the challenge as a starting point for what could be done with the data and code provided. Multiple datasets can have the same recommended challenge.
  6. If you have an interesting problem where regenerating the dataset from the provided code is quick and easy (i.e., can be done on a laptop in a few minutes by a user with no special expertise and with no need to install software other than Python and standard Python packages), we can link to just the code.
  7. It is not necessary to provide a link to a published manuscript. However, citing relevant manuscripts is one way to acknowledge the use of open datasets and code.
