In this demonstration we introduce Gelee, our online platform for the hosted specification and cooperative execution of lifecycles of artifacts of any kind. With Gelee we aim at filling two lacks we identify in current cooperative software systems when it comes to unstructured, artifact-based works (e.g., the writing of a project deliverable): the lack of state and the complete lack of automated actions. Lifecycles allow us to model the state of any object, and if we focus on online resources (e.g., a Google Doc) then we can also automate some lifecycle actions. If we apply Gelee to composite artifacts, e.g., a set of web services, lifecycles provide for the human-driven orchestration of services.

13. Gelee: Desiderata Define (models and templates) Execute actions on resources (NOT automate the progression of the lifecycle) Monitor progress Easy!! no need to learn, no complexity No overhead, no rigidity: I do what I want, not what the tool or the model wants Tolerant: maybe the model is incomplete, maybe I don’t know the actions I want to do or where to apply them Hosted, web based, lifecycle management as a service Lifecycle Management of Web Artifacts 8
