WTP Architecture Working Group

WTP Architecture Working Group

Plans

• Update our high level architecture document

• Make current with how things currently are (add, JSF, JPA, DTP, etc.)
• Make current with how we want things to be (improved componentization, etc)
• Make a Projects View
• Make a Features View

• Make recommendations that are important to release 3.0, such as

• Can we install and/or enable proper capabilities for various install scenarios?
• Should/can some plugins move to better components/features?

• Work with project leads for the "bottoms up" perspective, and address what's realistic

Minutes 9/14

Attendees: Konstantin, Nitin, Cameron, David W, Tim dB

Some of the discussion topics:

• Long term, should/can we use the build to enforce architecture?

• We can build things separately, but build currently assumes things go in a single order, i.e. once things are built they are available to all future components that build.

• Should the foundation supply build infrastructure?

• They already provide machines and much infrastructure.
• Build project has been suggested before, and other teams have tried to promote their build technology. There has been little interest.
• Maybe just common scripts or mechanisms for sharing?

• WTP structure is now several projects, each with core vs UI and wst vs jst split.

• Suggestion of packaging individual features or components for download. Could be on a separate download page, but would allow adopters to get exactly what they want.

• Is that overkill?
• Unclear how 3.4 provisioning work might affect features.

• We should break components up as wst/jst when we look at dependencies.
• Will want to eventually investigate core/UI split too.

• Should tests be included as part of a component?

• In practice we should have component level tests (part of a component) and project/cross-component tests. In reality most tests are component level, but some components have cross-component tests too.
• General agreement we should look at our dependencies without tests (to investigate the clean/runtime view of things) and also compare to see what dependencies tests add.

• Discussed Konstantin's visualization tool, Tim's dependency tool

• Cyclic dependencies are bad. :)

• What about other dependencies, esp. JDT?

• Should come up with a view of what requires JDT and what doesn't.
• JEM and EMF both have non-JDT/JDT split as well.

Actions:

• Konstantin: Check on legal issues and send out source to tool
• Tim: Start modifying tool to read K's component format, start editing existing wiki page, setup next meeting
