The difference to a usual standard is referring to the likelihood of the standard getting changed by feedback from pragmatic applications. In contrast to standards that are developed by large committees where iterations tend to be slow and sometimes complicated. I believe JSON is often an example for a living standard because it contrasts the numerous XML standards, which are so extensive that no or very few applications implement it to the letter. Another example for the attempt to develop living standards are RFCs, where input is desired to adapt a possible future standard.
