Choosing Licenses
According to IvI policy (opens in a new tab) (see R5), all code and data must have an associated license.
A license is a text document that explains if and how a dataset or software package is permitted to be reused by others. If you do not include one, by default that work is under exclusive copyright; no license, no permission. Releasing code or data with no license (opens in a new tab) means that legally, "nobody else can copy, distribute, or modify your work without being at risk of take-downs, shake-downs, or litigation."
When you make your data or software available, it is important to choose a license that is in compliance with any licenses of other software you have included. For example, if you have a software dependency with a restrictive license, you cannot legally release your software with a license that is more open than that of this dependency.
