The Data Ethics Framework was created to give guidance to federal workers as they acquire and work with data, but the advice can be applied to non-governmental data work. These seven tenets were published in the framework:
In U.S. law, intellectual works (books, recordings, images, etc.) are the property of their creators. These creators own the exclusive rights to copy and distribute their work from the moment the work is created. They may sue others who copy or distribute their work without permission. You can find the text of the law on the U.S. Copyright Office web site.
As decided in Feist Publications, Inc., v. Rural Telephone Service Co., data are not covered under copyright law. If you publish data you have collected, you would own the copyright to any text and visualizations that describe or organize that data, but others would be able to reorganize the data and illustrate it in different ways without infringing on your copyright.
Be aware: If you publish someone else's data, you may still be sued if the original publisher feels your work is too close to their own copyrighted work.
