7. Design Principles
• Browser-based, thin client
Data are never local
Metadata are pulled client-side
Dataverse’s DDI metadata
TwoRavens’ generated metadata
Data are pulled server-side
• Device independent and broadly accessible
Only requires an internet connection
Does not presuppose expert statistical knowledge or
experience with statistical software
