Integrating applications in a single framework

Today's businesses routinely use an array of system applications and often need to access applications outside their own perimeter. Integrating all applications within the same organization and even sharing them among different organizations has become a key priority for system integrators and companies worldwide.
Integrating applications in a single framework
A Greek IT firm has developed ONAR, an ontologies-based enterprise application integration framework that addresses company needs for a unique platform incorporating all user applications. ONAR facilitates the interconnection of heterogeneous information systems, resource sharing and services provision, lowering integration costs and improving on the time requirmenents associated with the method.

The integration process comprises five separate steps. The first step is the Conceptualisation phase, during which the application concepts are defined using ontologies. The Correspondence phase follows, when the concepts are corresponded to the system repository. During the Exploitation phase the software components are developed in order to provide access to the application repository. The final phase is the Publication phase when the deployed XML Web-services are registered in an enriched UDDI registry.

ONAR is based on the Semantic Web technologies providing semantic conceptualisations representing the applications. Using ontologies allows the creation of shared semantics of these representations allowing multiple applications to use these concepts through the derived Web-Services. The derived Web-Services are not linked to the technical and architectural systems and are thus independent of their inherent limitations. Furthermore, they do not affect the status of the legacy application.

This novel framework is associated with considerable cost savings and can also reduce the time required by the integration process. Its ontology-based nature combined with the use of a semantically enriched Web-Services registry constitutes a significant innovation compared to existing solutions in this field.
