Yes, totally agree. For example, where would file-systems be without bit-maps?!

My problem is that my data is more or less schema-less. I know about a certain amount of properties that might show up, but similar to the "Browser-fingerprint" problem, I might receive more and more properties I haven't planned into my schema/bitmap/bitvector layout. Knowing all varieties is then similar to an algorithm that requires me to have properties in a fixed order, to align them to each other.
