Developing a frame work

I have to develop a framework in such way that it has to support work
flows and persistance storage in ruby on rails .for example if we take
office automation system ,if the user interacts with the system,if
that event results in workflow, the workflow system has to kick in
and if user wants to store the data ,the persistance thing will come
to picture .generally the object we want to circulate between
workflows is a spread sheet
can anyone supply pointers for this how to approach

Try elaborating better.
