One of the important aspects of REST (or at least HTTP) is the concept that some operations (verbs) are idempotent. As Gregor Roth said several years ago: The PUT method is idempotent. An idempotent method means that the result of a successful performed request is independent of the number of times it is executed. Idempotency is also something discussed in the SOA Design Patterns.
In English grammar, a referent is the person, thing, or idea that a word or expression denotes, stands for, or refers to. For example, the referent of the word door is the object door.. Referring words are words, such as pronouns, that point back to other items in a text (anaphoric reference) or (less commonly) point ahead to a later part of the text (cataphoric reference). See Examples and Observations below.
