Short-term plan for t2 work for the 2008-06 release (Taverna 2.0)
Key units of work
Based upon Tom's original Roadmap
document. See also the t2 architecture, the t2 annotation model and t2 talks by Tom and by Stian.
- DataManager / DataFacade refactoring
- Data Reference Handling
- Requires some modification of the Activities internal data handling.
- Data streaming
- Peering
- Caching support
- Update of API wrt annotation framework
- Its currently out of sync with Toms design documents.
- UI manipulation of annotations
- Improved Activity palette
- Improved monitoring
- Steering
- Provenance capture
- Provenance store
- To act as a service, and allow import/export of provenance generated by other workflow system
- Graphical dataflow construction
- Ability to add an activity from the Service Palette
- Port current UI to new model.
- Negotiation of security credentials (tsunami)
- Session management
- Dataflow serialisation
- Save and Load a dataflow independently of T1
- Workflow egine swarming
- Multiple enactors to be collaboratively responsible for the invocation of a shared set of workflows.
- Plugins
Other areas
- Scalability and data throughput testing framwork
Must have for June

- Implmenetation of the security agents (ws-security)
- Augment existing WSDL processor
- Fix API's
- Security agent API's fixed
- Refactoring of Data manager
- Annotation API
- Loading / Saving / Translating dataflows
- Documentation

- Website
Graphical editor
Workbench
- Start with a new blank workbench
- Update zaria to allow frames to be full screenable
- Abstract out action handlers for entities.
Contextual View
- Clicking on a processor in the Graph view reviews a context view to configure that processor
- Activities
- Iteration strategy
- Annotations (mime-types)
- Dispatch stack
- Port action handlers
Graph View
- Update current dot view to react to mouse events
- Update dot view to work with a dataflow model
- Draggable connecting of ports
- Drag an activity onto an existing processor adds it as an extra activity related to that Processor.
Tree view
- expansion state of the tree view is also reflected in the graph view (e.g. expanding a nested workflow)
Activity Palette
- linked with feta
Annotations
- Shim groupings - bound to a service - marked as upstream/downstream
- Mime types
- Refactoring API
- Storing (refer to annotation model doc)
Security
- Fix the API
- Naive implementation of agents and container
- Modify existing WSDL activity to
- UI Interface to the keystore
- Target the caGrid services to start with
DataManager refactoring
- move the translator logic inside the datamanager
- factor out the interfaces
- factor out the blob store
Loading / Saving / Translating dataflows
- Finish serialisation for dataflow objects
Documentation
- Help menu
- Embed docs into the T2 application.
- T2 Examples
- Tutorials
- Match style sheets to website
- Video tutorials
Demonstrate improved scalability & performance
- Create a set of test workflows
- Find users with suitably intensive workflows
- Setting up a scalability testing and measuring framework
- connect to remote enactor with jdwp and measure "what its doing"
Provenance capture & visualisation
- Capturing of basic provenance
- Embedded database by default in downloaded version
- Viewing of intermediate values
