Abstract:

Metadata is still a hot topic for information sharing. It usually does not support information semantics management. This paper orients to semantics-b  ased information resource sharing, and focuses on the design of a integrative metadata model by using the ontology theory in the AI domain. The metadata model is used to describe the semantics of information resources. We present a specific instance of school based on the rnetadata model, and then represent it using OWL. We also use the metadata to implement the metadata specification template of information resources and the prototype of metadata desc ription tools.

Key words: （metadata model, ontology;semantics, OWL;semantic overlay network）
