Declarative DSLs

• A declarative style DSL is good for …
  • Configuration data
    • Relatively stable
  • Structured Data
  • Moderately sophisticated users
• Probably wouldn’t use for …
  • Transactional data
  • Unsophisticated Users (i.e. those who would be uncomfortable with a text editor).
    • A GUI or Web-based interface would be better for these users
    • (and Rails makes this easy too).
