Thank you very much. I will investigate both approaches.

Hello everyone,
I am considering possiblities how to implement workflow in jcr
repository.
What I would like to achieve is to have states for each nodes and
control transitions.
I know that this kind of functionality generally might be achieved
with jbpm library.
Have you got any experience you can share in combining JCR with
workflow libraries or other approaches to this issue?
well, I think workflow and jcr are orthogonal to each other and the
only connection could be the path, for example /foo/bar/document.pdf
Re the workflow itself I think you can re-use an existing package or
introduce your own interface (and corresponding implementation) as
for
example

I also think that workflow and storage are orthogonal.
But, you may need to query the repository for getting contents
with some given metadatas and a given workflow state (or if it has
been in the state "Published" yesterday...).
If the workflow is not stored into the repository, you will need to
query first the repository and then the workflow engine with results
(or the opposite) and this will not be efficient if you have a lot of
contents.
That's why i have coded a JCRWorkflowStore for the OSWorkflow engine
in order to have efficient "hybrid" queries.
The first version of this WorkflowStore can be obtains here :
http://jira.opensymphony.com/browse/WF-465
Moreover if the worflow is stored into the repository, then the
integrity is
/ maintained./
