Let's see if i get this right. In jPDL 4 i want to add annotations. Basically, annotations are key-value pairs that you can associate to all process elements. As extensions would like more infomation inside of the process (UI forms, simulation, prediction,...) they can be added in a standard way without the need to write a parser for it. e.g. <task name="ship"> | <annotations> | <string name="task.form" value="ship.xhtml" /> | ... | </annotations> | </task> in jPDL 4, there will be one way on how to write objects in xml. it will be used here for annotations, but also for the configuration file and to specify initial values for variables. alternatively users should be able to write their own parsers to extract the information from a process archive and put that information somewhere in the process definition. does this feature match the requirement that you both are explaining ?
