On this topic, I find it disappointing (at least in the footer and the
"English explanation of WikiKids") that Kennisnet hasn't made the
project's content available under a free license. On edit pages it
notes:
"GEBRUIK GEEN MATERIAAL DAT BESCHERMD WORDT DOOR AUTEURSRECHT, TENZIJ
JE DAARTOE TOESTEMMING HEBT!"
which means:
"USE NO MATERIAL WHICH IS PROTECTED COPYRIGHT, UNLESS YOU HAVE TO THIS
END AUTHORISATION!"
But beyond shooing away plagiarism, there doesn't seem to be any
obvious mention. They've even removed the default mention of the GNU
FDL that appears by default on Wikia hosted wikis.
