1# Open Source Licenses 2 3## Overview 4 5The licenses in this directory are taken from [SPDX](https://spdx.org/licenses). 6 7## Naming Convention 8 9The name of the file is the same as the identifier on the SPDX website with an 10extension of `.txt`. For instance, the "Academic Free License v1.1" license 11would be in a file called `AFL-1.1.txt`. 12 13### Special variants 14 15Some licenses have special variants. E.g, the Apache-2.0 license has optional 16sections in it. And some licenses, like GPL-3.0, have a short "header" variant 17that's included in source files. The full text of the license and each of its 18special variants will be mapped to the same license. (Though the "header" form 19shouldn't be used in `LICENSE` files.) 20 21#### Header Variants 22 23The name of a license header variant is `<identifier>.header.txt`. So the 24GPL-3.0 header variant would be named: `GPL-3.0.header.txt`. 25 26#### Optional Text Variants 27 28TBD 29
