Here are the guidelines for understanding the problem of and developing specification for the Component Model.

Approach

  1. Capture requirements as use cases;
  2. Study use cases and extract a set of desired properties for these use cases;
  3. Come with a design that satisfies all desired properties;
  4. Extrude building blocks out of the design;
  5. Iterate until success criteria is reached.

Success criteria

  • The use cases:
    • reasonably cover a set of component model needs on the Web.
  • The properties:
    • completely describe the set of use cases;
    • are orthogonal to each other.
  • The building blocks:

Design Principles

  • Reuse existing mechanisms as much as possible, gently extending them if necessary;
  • Study popular patterns in existing Web frameworks and pave the cowpaths when appropriate;
  • Encourage each building block to stand on its own merits.
