Rich Metadata Mediated UI development

What would you automate into your boilerplate code after having 10 years of writing database applications? Here are some links to promising projects/essays:

• Andromeda
• Django Admin
• Dataphor

  Promises: User interface “hints” integrated with the data model

• Naked Objects
• MS Access and Query By Form
• I like how CodeIgniter makes it possible to compose declarative data validations e.g. “valid_email|matches[email_confirm]|min_length[6]“
• We need standard ValueConverters for currency, URL, dates and email addresses
• Someone should write an essay on why database synchronization for off-line applications is a bad idea, and why journaling works better
• More ideas here – There are no attributes – CQL sounds cool

What are your thoughts here? Are there any other notable projects in a similar vein?
