The Joint Battlespace Infosphere (JBI) architecture defines the Information Object (IO) as its basic unit of data. This research proposes an IO engineering methodology that will introduce componentized IO type development. This enhancement will improve the ability of JBI users to create and store IO type schemas, and query and subscribe to information objects, which may be semantically related by their inclusion of common metadata elements. Several parallel efforts are being explored to enable efficient storage and retrieval of IOs. Utilizing relational database access methods, applying a component-based IO type development concept, and exploiting XML inclusion mechanisms, this research improves the means by which a JBI can deliver related IO types to subscribers from a single query or subscription. The proposal of this new IO type architecture also integrates IO type versioning, type coercion and namespacing standards into the methodology. The combined proposed framework provides a better means by which a JBI can deliver the right information to the right users at the right time. | A Jbi Information Object Engineering Environment Utilizing Metadata Fragments For Refining Searches On Semantically-related Object Types
