Simplest Definitions

• Data
• Digital object
• Objects are streams of bits
• Information
• Any tagged data, which is treated as an
  attribute.
• Attributes may be tagged data within the digital
  object, or tagged data that is associated with
  the digital object
• Knowledge
• Relationships between attributes
• Relationships can be procedural/temporal,
  structural/spatial, logical/semantic, functional
