Goal

• Define, monitor, automate the lifecycle of any
  resource
• Anything that can be referred to by a URI
• For non-experts (average scientist is the target)
• That is useful and used
• We are examples of target users, so we can see if
  its useful ?

3
Projects

• Proposals, deliverables, papers, complex
  artifacts
• Each of these artifacts today go through a
  lifecycle
• Project mgmt includes defining and monitoring the
  lifecycle of artifacts

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
  dont know the actions I want to do or where to
  apply them
• Hosted, web based, naturally integrated.

6
Today?

• Not really lifecycle, focus on entire project
• No automation, templates
• Still need to keep it updated by hand

7
Workflows

• You can model, automate, monitor
• But
• Complex, Heavy
• Rigid
• For programmers
• Flow of actions

8
Gelee Key contributions

• Same simplicity of MS Project, but, enable
  automation, templating
• On any kind of resource
• For any kind of user
• Easy, tolerant, no learning, hosted, just like
  the web
• Light-coupling
• Transparent extensibility
• Integrated with the resource management
  environment

• Trivial phases, state, deadlines
• Bind to any resource
• Unstructured, unfinished
• Templates

• Model and execute
• Type-specific (abstracted to the possible extent)
• May have parameters

Binding model and flexibility (1)

• Lifecycle is descriptive, not prescriptive
• Instance Owner can jump from any phase to any
  phase
• Instance Owner can change the model associated to
  the instance
• Template Owner can change the template
• Transparent wrt instances, migration is trivial
  (phase mapping from old to new)

15
Binding model and flexibility (2)

• Edit or skip actions
• Action parameters entered at definition time,
  instantiation time, runtime
• Resource can be changed
• E.g., From gdoc to wiki

Lightweight infrastructure

• A human lifecycle engine
• Adapters provided externally (not only via
  plugins)
• Easily extensible
• Essentially the application is limited to UI and
  a simple res mgr and log DB

Summary

• Lifecycle management made easy, hopefully
• Useful for modeling, automation, monitoring
• Leaves the owner in control, not imposing, not
  intrusive
• Lightweight architecture, wiki-extensible
