[news.eclipse.technology.epf] Re: Modeling SPL processes with SPEM 2.0

["Peter Haumer" <phaumer@xxxxxxxxxx>]

Hello Orlando.
Unfortunately, there is still no SPEM 2 metamodel.  I am preparing another 
OMG submission for Monday right now, which has changes in respect to the 
last submission that still incorporates change requests from the submission 
partners.

When you perform a task that produces a guideline then this guidelines is by 
definition a work product.  Hence you would model a work product (or 
artifact) called guidance and list that as the output.  The guidance that 
you create in EPF are the instances of such a work product guidance.

This is a tricky topic referred to as meta-modeling.  The UML Infrastructure 
document explains this much better than I can, but: SPEM or EPF processes 
define a model (also sometimes referred to as M1 objects).  In your case you 
seem to be creating a process about process modeling itself (which makes it 
a bit more complicated to understand).  Even so, that process can describe 
how you create work products called guidance.  The instantiation of your 
process (on the M0 level) would produce concrete guidance instances such as 
"Run a brainstorming session".  These guidance instances can be created and 
managed in the EPF tool.  It is just a coincident that your work product is 
part of the SPEM meta-model, but there is no need for an extra association. 
Otherwise, you need to link every other concept of SPEM to task as well, 
e.g. for a task that produces a process, a task that produces a work product 
definition, etc. These are all plain work products.
