automated procedures which are less error prone
more timely reporting and, consequently, dissemination
enhanced coordination with other international organisations

Metadata principles
All statistical data being shared or disseminated, internally or externally, must have appropriate metadata
Statistical metadata must be consistent All metadata must be created only once
