I read that often from you, maybe you just ask questions the wrong way, or you could ask before you have a problem? What about asking how you should do it instead?
Also it seems you feel personally attacked by just factual replies, that is not intended, maybe you misinterpret things to your disadvantage?
As the livecd is image-based, (opposed by the DVD or dualarch cd or netinstall, which are package based and allow for customisations of the installation via custom package selection) you can only install the whole thing, and customise afterwards. So you could still install task-kde4 afterwards, if some parts of KDE are not available, which also applies to a default DVD install, which does not bring along ALL of KDE. But IIRC a default install, be it from DVD or livecd, should have Nepomuk, but i'm not quite sure for the livecd.
That why i said "it
should be present there".
