flowtype is not fully implemented in the current release candidate.
but processes can be used.

processtype is a special case of object/topic type with two additional
properties called prior-state and post-state, where prior-state and
post-state can be two states of any topic. for example: a book is
issued to be from a library. the book will have in its prior state the
issue property set to nil, and post state will be set to true.  these
two snapshots of the book will be used as prior state and post state
values to a processtype called "issuing a book".

Hope that helps.
