 **Notes:**
 
 1. note that `somesy` does not support setuptools *dynamic fields*
 2. `package.json` only supports one author, so `somesy` will pick the *first* listed author
 3. `fpm.toml` only supports one author and maintainer, so `somesy` will pick the *first* listed author and maintainer
-4. unlike other targets, `somesy` will *re-create* the `codemeta.json` (i.e. do not edit it by hand!)
+4. `pom.xml` has no concept of `maintainers`, but it can have multiple licenses (somesy only supports one main project license)
+5. unlike other targets, `somesy` will *re-create* the `codemeta.json` (i.e. do not edit it by hand!)
