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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
