The "hello world" example describes the repo structure a little. Then, it says, "for more information on the Artifact repository, refer to the Red Hat JBoss BPMS User Guide."
The only place I could find artifacts in the User Guide (by looking at the ToC), the only section about artifacts doesn't mention anything about repositories or the repo structure.

Hey Deon - there is some confusion here regarding 'artifacts' and items in the 'artifact repository'.
The user guide does describe the usage of the repository in much more detail in terms of modeling .
Hope this makes sense. If not, please feel free to reopen.
Marking this as NOTABUG.
