Where Do We Want To Go

February 27, 1999

---

What are the real risk areas?

• Lots to learn
• A totally different approach, hard to learn.
• Takes longer at first
• Fear of demotion to mere assembly
• Will it really work in our domain?
• Will it work soon enough to be worth trying now?
• Might lose our advantage while distracted by trying UHR.

Misc

• A process that uses the BA could be useful.
• Need to take existing app and/or framework, see how to do it with the BA.
• Need convincing way to justify management decision to use UHR.
• Need a strategy to get it adopted by an organization.
• "If it's not visible nobody cares as long as it works."
• Nice, step by step tutorial, using 40 systems as examples
• Examine performance issues
• Rewrite BTree
• Do MessageDefs in MessageSources in JCON.
• Document Param subsystem.

Benefits we want to use

• What we build is based on very sound archtitecture
• Loose coupling
• Configurable solution
• Fast product cycle

Tools Needed

• Visual UI parameter builder
• Ability to plug in custom parameter editors
• Visual parameter type editor, expert and non-expert levels
• Tell it a little and it does a lot
• Ability to translate Use Cases into DK
• A ParamStore that uses XML as the file format
• One button deployment
• Configuration report generator, like JavaDoc. What are possible parameters for this framework, what are its full features.
• 3 main editors - System, Part Shop, Shipper Tool
• Ability to explore System Tree to find info about part, such as the model its in, now to use it
• Validation as you go, avoid giving up strong typing advantages, go both ways.
• Validate dependencies between parameter files
• Debug mode, watch Messages as sent
• Generate state diagram of system or what just happened
• Ability to record and replay Messages to simulate system behavior
• Ability to deserialize a part, rather than provide a Param to a part instance

Infrastructure - The Legs

• Website, CVS, overnight builds, various
• Dedicated UHR list or group for hardcore developers

Microkernel Issues

• Apply Infinite Extensibility
• Better ParamAccessor
• Plugpoint for optional interfaces for parts
• Thread safe, such as two versions
• Various events, such as part added to container
• Allow Message stream to be monitored
• Final MessageListenerInfo, MessageSourceInfo

Work Groups

1. Tutorial and documentation
2. Visual Editor
3. Infrastructure
4. XML custom ParamStore
