Business architecture became a well-known tool for business transformations. According to a recent study by Forrester, 50 percent of the companies polled claimed to have an active business architecture initiative, whereas 20 percent were planning to engage in business architecture work in the near future. However, despite the high interest in BA, there is not yet a common understanding of the main concepts. There is a lack for the business architecture framework which provides a complete metamodel, suggests methodology for business architecture development and enables tool support for it. The ORGMaster framework is designed to solve this problem using the ontology as a core of the metamodel. This paper describes the ORG-Master framework, its implementation and dissemination. the presentation was given within the SOMET 2011 conference: http://www.somet.soft.iwate-pu.ac.jp/somet_11/ see the text in proceedings here: http://www.booksonline.iospress.nl/Content/View.aspx?piid=21454 Kudryavtsev, D., & Grigoriev, L.
