Thank you for your reply. Now I know that I did not explain the problem well enough.

The problem is that there are obvious facts that partly seem contradictory (certainly not only) to me.

Of course JPDL is (one of) the process languages used by jbpm.

The obvious facts / unanswered questions are:

- JPDL is already part of the NOT-jpdl project.

- The sizes of the "jbpm-jpdl" download packages are nearly as big as the sizes of the "jbpm" packages. 

- When I go on the "latest file releases" page:
http://sourceforge.net/project/showfiles.php?group_id=70542&package_id=145174
  and click on package "jbpm jpdl 3", I see a donwload list that is mixture of "jbpm" and "jbpm-jpdl" packages.

- At the lower part of the list, only "pure" jbpm packages are listed. In the upper part of the list the "jbpm-jpdl" packages appear by degrees, as if "jbpm-jpdl" was a successor of "jbpm" (first jbpm-jpdl-3.2.Alpha1, then jbpm-jpdl-3.2.Alpha2, jbpm-jpdl-3.2.Beta1, jbpm-jpdl-3.2.Beta2, jbpm-jpdl-3.2.GA, jbpm-jpdl-3.2.1, jbpm-jpdl-3.2.2)

- At the top of the list, ONLY "jbpm-jpdl" packages are listed. This fuels the impression that the "jpbm-jpdl" project is a successor of "jbpm".

- There is a complete "jbpm-jpdl" starters kit which is named "jbpm-jpdl-suite-3.2.2.zip". Its web application seems more up-to-date than the current "jbpm" starters kit web application ("jbpm-starters-kit-3.1.4"). This also fuels the impression that the "jpbm-jpdl" project is a successor of "jbpm".

With these facts in mind, I want to ask again:

What exactly is the difference between the "jbpm" project/download packages (obviously containing JPDL), and the "jbpm-jpdl" project/download packages?

Why are they overlapping (jpdl is part of jpbm) and concurrently competing (with two different web applications)?
