Content Model - Definition

• a set of standardized behaviors
• logical assemblages of content units
• disseminators encapsulating the data preserved by
  the digital object
• methods to end users, applications, and other
  digital repositories

8
Our Approach to Modeling Behaviors

• Decompose disseminators into base groups or
  atomic units (behaviors)
• We refer to these groups of behaviors as Content
  Modeling Fragments.
• Support inheritance and polymorphism
• Output is of presentation-neutral nature

AssetActions

• Promote interoperability
• An XML-defined set of actionable URIs
• Made up of action groups

Ideas for the Fedora community

• Standardization of object profiles
• Defining reusable sets of disseminators
• A code registry of Content Models and
  disseminators
