Scenario 3: Component Integration in heterogeneous scenariosSuppose and Organization that needs to configure a new product/platform/service from already existing and tested components (applications, products, services)E.g.m: Service Integration, Integrated Development Environments What is common to all these cases?

20What we seeGiancarlo GuizzardiResearch

My current main line of research is concerned with the application of foundational ontologies in the development of philosophically and cognitively well-justified methodological tools for conceptual modeling in computer science. On this topic, I have been working for many years in a close collaboration with Gerd Wagner (Brandenburg University of Technology at Cottbus), Nicola Guarino (Institute for Cognitive Science and Technology, Laboratory for Applied Ontology, Trento), and Heinrich Herre (Formal Concepts Group, University of Leipzig) in the context of GFO/GOL (General Formalized Ontology/General Ontology Language) Project.

From 2000 to 2005, I have worked with Marten van Sinderen and Luis Ferreira Pires in the ASNA (Architecture and Services of Network Applications) Research Group in University of Twente in The Netherlands. As a result of my work there, I have received a PhD (Cum Laude) from the same university. The results of my PhD research have been published in the book Ontological Foundations for Structural Conceptual Models.

Since May, 2005, I have been holding an Associate Researcher position in the Laboratory of Applied Ontology (LOA), which is part of the Institute of Cognitive Science and Technology (ISTC), in Trento, Italy. Since March, 2006, I have been also holding an Associate Professor position at the Federal University of Esprito Santo, in Vitria, Brazil.

My other research interests include Software Engineering (in particular Domain Engineering, Semantic Application and Interoperability of Tools, Semantic Software Environments, Software Reuse), FOL and Modal Logics, Design of Domain-specific visual languages, Formal Languages and Design Methods and Architectures for Open Distributed Systems (including Enterprise modeling, Distributed Multimedia Systems and Context-Aware applications).

What we can doDefine ClassesDefine relations between classesDefine classes using set-theoretical operatorsDefine datatypes and datatype propertiesDefine (binary, directed) domain relationsDefine relations between relationsDefine formal meta-properties of relationsImportant Limitations and Unanswered QuestionsWhere do the formal meta-properties of relations come from?Where relations have to be binary? No composition constructor and, thus, one cannot even define even simple properties such as Uncle:

4848Explore the domain

This should be clear from the business requirements - it might be food or music or gardening or...

Concentrate on modelling real (physical and metaphysical) thingsnot web pages - try to blank from your mind all thoughts of the resulting web site.

This work should never stop - you need to do this through the lifetime of the project as you refine your understanding.

Michael Smethurst, BBC

Identify your domain objects and the relationships between them

As you chat and sketch with your domain expert you should build up a picture of the types of things they're concerned with. As your knowledge of the domain increases you'll build up a picture of how your objects interlink.

Bear in mind you're trying to capture the domain ontology - this isn't about sketching database schemas.

The resulting domain model will inform the rest of your project and should be one of the fewartifactsyour project ever creates.
