That's a cool presentation. And the module looks great... except, why do I have to program Perl inside an XML file? This makes my skin crawl:

<workflow> <type>myworkflow</type> <state name="INITIAL"> <action name="upload file" resulting_state="uploaded" /> </state> <state name="uploaded" autorun="yes"> <action name="verify file" resulting_state="annotate"> <!-- everyone other than 'CWINTERS' must verify --> <condition test="$context->{user} ne 'CWINTERS'" /> </action> ...

I'd be much happier with:

my $workflow = Workflow::Generator->new(type => "myworkflow"); $state = $workflow->add_state(name => "INITIAL"); $state->add_action(name => "upload file", resulting_state => "uploa +ded"); $state = $workflow->add_state(name => "uploaded", autorun => "yes") +; $state->add_action(name => "verify_file", resulting_state => "annot +ate"); $condition = $state->add_condition(test => \&check_file);

It's more conscise and all the power of Perl is available for making repetitive structures from common data. If I ever decided to use Workflow I think Workflow::Generator would be my first project.
