Large, complex organizations such as the United States Air Force (USAF) must use, manage, and administer software systems which are massive in size, international in scope and complex in operation. These USAF systems have evolved over a period of time, were written in different languages, have obscure relationships, and serve purposes that may be hard to visualize. This leads to a lack of understanding of the enterprise data and its attendant relationshipswhich makes any system modernization or interoperability effort a particularly demanding challenge.There is a need for the development of a semi-automated approach to quickly analyze the syntax and semantics of the current data environment from structured and unstructured information and evolve it for system interoperability and modernization.Connote is a technology which uses innovative concepts such semantic web technologies, ontologies, code parsers, and analysis capabilities to ingest, parse, and display the contents, relationships, and structure of legacy software.This technology can be evolved and leveraged to meet the needs of the USAF for legacy system replacement or integration.legacy systems,systems integration,System Replacement,semantic web,model-based systems engineering
