It will provide a way to retrive all the availeable information. It will look first in the XML shipped by the server, using KNS::Entry and KNS::Author, then, if it is a KNS2 package (so, extension .kns or .plasma), it will use also metadata.desktop to retrive additional informations. It probably won't inherit QStandardModelItem, altough the concept will still remain there.
