• 1) Welcome to the Statistical Knowledge
  Network
• a registry of objects that provide meaningful
  knowledge structures (ontologies) with rules
  constraints to ensure safe usage
• tools to support user actions find, display,
  annotate, manipulate, and contribute
• - tools to help diverse users understand
• a community of people who collaborate
• and ways to provide feedback for continued

3) Government agencies, organizations, and
registered individuals can contribute to the
Statistical Knowledge Network. Some objects will
be registered manually, while others will be
added automatically by web crawlers or other
processes. Metadata descriptions and links will
be stored, but most objects will remain with on
the contributors server. Tools to support the
Contribute action will include input validation,
indexing, record editing, and deletion. Services
include version control, security,
authentification, and backup. Introduction
