Vis 2009 Tutorial
After discussion, it seems that the tutorial is best broken into two distinct pieces: A user-centric portion focused on using VisTrails, and a power-user or developer-centric portion focusing on plug-ins, mashups, etc.
Working Outline
- Introduction to Provenance and VisTrails (1h 30m) - Presenter: Claudio/Erik/Juliana/Manu (?)
- Brief view of plugins and released features of VisTrails
- Define provenance, explain why it is important for data analysis and visualization
- Introduce VisTrails, explain the differences and similarities between VisTrails and other vis and scientific workflow systems
- Say it is open source
- Multi-platform: written in Python+QT
- Downloaded 1000's of times
- Shipped with packages: XXXYYYZZZ
- User-contributed packages: XXXXXXX -- you can add your own! (more later)
- Explain the version tree and the action-based provenance model
- Show features that are enabled by the action-based provenance, and how they can help in the process of analyzing and visualizing data
- Going back and forth on the tree
- Automatic capture of changes
- Compare different workflows and their results
- Exploring parameter spaces
- Querying workflows by example
- Refining workflows by analogy
- Discuss how the action-based provenance model can be combined with interactive tools
- Give a brief overview of the plugins
- Show videos for a couple of them and point to the detailed tutorial of how to build a plugin later.
- Basic hands-on usage of VisTrails (1h 30m) - Presenter: Manu (?)
- Building Simple Pipelines
- Using PythonSource
- Connecting to databases
- VisTrails as a Server
- Advanced hands-on usage of VisTrails (1h 30m) - Presenter: Erik
- This will all be in the context of a very specific example - My first thought was to use Gil's data, as it has many very nice features that build a nice story, but problems with releasing data are pushing me towards a CMOP example.
- Organizational principles of the History Tree - QBE, Analogies, Parameter Exploration -> New Version
- vtkInteractionHandlers - Slicing and dicing data
- PythonSource as callback definition - Picking specific elements
- The workflow debugger
- Transforming VTK pipelines into VisTrails workflows --- modified version of Dave's script to get all VTK example into a .vt, and show how to query/search that.
- Developing a plug-in (30-40m) - Presenter: Manu (?)
- Plug-in architecture overview
- Different implementation strategies
- ParaView Plug-in demo
- New Extensions to VisTrails (50-60m) - Presenter: Claudio/Erik/Juliana/Manu (?)
- Display Wall
- Provenance Rich Publications
- Mashups
- Repository
- Web-based execution (?)
