Here's the abstract:

  A library implementing transducers — composable algorithmic
  transformations.  Scheme has many different ways of expressing
  transformations over different collection types, but they are
  all unique to whatever base type they work on.  This SRFI
  proposes a new construct, the transducer, that is oblivious to
  the context in which it is being used.

SRFI Editor
