The aim of the tutorial is to provide a practical introduction for researchers and practitioners to the BORO methodology, an ontology-based systems re-engineering and modernisation approach. At the core of the methodology is the BORO Foundation. The tutorial will firstly introduce the foundation and then the methodology. It will start with a series of worked examples that explain the philosophical principles underlying the foundation. These will then be developed in further business based worked examples to illustrate how the methodology works and how the philosophical principles drive the methodology and analysis. The examples will showcase how the use of BORO promotes flexibility and reuse of the re-engineered models.

This paper presents a report on work in progress of a Synthesis of (selected) State of the Art Enterprise Ontologies (SSAEO) – which aims to produce a Base Enterprise Ontology to be used as the foundation for the construction of a Core Enterprise Ontology (CEO). The synthesis is intended to harvest the insights from the selected ontologies, building upon their strengths and eliminating – as far as possible – their weaknesses. One of the main achievements of this work is the development of the notion of a person (entities that can acquire rights and obligations) enabling the integration of a number of lower level concepts. In addition, we have already been able to identify some of the common ‘mistakes’ in current enterprise ontologies – and propose solutions.
