Profile manager of firefox

If you want to add new profile, you have to start firefox from command line (cmd) with option -ProfileManager. It will open a dialog box for you where you can manage your firefox profiles.
If you don't want to start firefox from command line every time, when you need to be loaded to some other than default profile, you need to create a batch file (with .bat suffix).
You can do that for example in notepad. In this file you have to add the following line:
START "" "%ProgramFiles%\Mozilla Firefox\firefox.exe" -P "yourNewProfile"

    rdf resource declaration-solution

    It is possible to define resource in one place and add properities in another like this:

    <rdf:Description rdf:about="">
    <rdf:type rdf:resource=""/>

    <rdf:Description rdf:about="">
    <rdf:name>Maria Juana</rdf:name>

    rdf resource declaration

    Data in the file is not written in the same order in which I need to process them.
    So my question is, whether should be all properties of one resource declared at one place (in one description tag) and thus whole file processed at once and only then created rdf.
    Or whether it is possible to add properties to previously declared resource anywhere in document during data processing?

    Finding the URL of KM Exercise english homepage

    There exists no automatic direction button (similar to the one which can be found on top right corner of the KM lecture's homepage) and I handled the problem in this way (I know almost nothing about html, xml and many other IT related topics):

    I thought both homepages (Lecture and Exercise) should be organized by the same person or at least in the same way. So I compared URLs of “english homepage” and “german homepage” of the “KM lecture” together. Their difference was just a simple “index.en.html” and I added it to the URL of german homepage of KM exercise.
