Sharad, Maven works with plugins for various tasks. Each plugin is a Maven artifact with its own version.
The install plugin handles installation tasks to local repository. You can read more about it here: http://maven.apache.org/plugins/maven-install-plugin/
So in this case, your Maven 3 is using a plugin called maven-install, and the /plugin's/ version is 2.3.1. 
That's perfectly fine.

Thanks for the reminder- wiki updated. No change needed for the settings.xml file, or its location.
