5. The computer-executed method of claim 2 , further comprising: generating a second set of bits based on the first set of bits wherein the second set of bits conveys at least the same information as the first set of bits; associating the second set of bits with a second version identifier that identifies a second format that is different than the first format; wherein the second set of bits comprises a second plurality of distinct subsets of bits; wherein each subset of bits of the second plurality of distinct subsets of bits corresponds to a different topic of a second set of topics; wherein a topic represented in each of the second plurality of distinct subsets of bits, respectively, is determined according to the second format.
11. The computer-executed method of claim 5 , further comprising: identifying a third subset of bits of the second set of bits that represents the first topic; and causing the third subset of bits to represent a value that is proportional to a value represented by the first subset of bits.
