What is the IID in Q_PLUGIN_METADATA(IID "...") and why do I need it

Hi, I am currently working on QT Plugins and came across the macro Q_PLUGIN_METADATA. Here you hace to define an IDD. Since now I always get an Parse Error at "IID" as an exception in the line
Q_PLUGIN_METADATA(IID QQmlEngineExtensionInterface_iid);
I need to understand what this IID actually does, where I will need it when reusing the plugin and why every example names the IID QQmlEngineExtensionInterface_iid without declaring it.
Help is really appreciated and I hope you can bring some light in this :) Thanks in advance!
