• A retrieval system that organizes these documents in a systematic way.
• Both humans and agents can easily conduct searches and queries against this repository.

What Swoogle Search?

• Find if suitable ontologies matching the user’s need already exist within underlying domain.
• User inputs specific term.
• Swoogle replies with existing ontologies that also use the term entered.
• Follow the link and see whether the provided ontology satisfies the need
• Query SWDs with constraints on classes and properties used by them.
