2nd International EDOC Workshop on Vocabularies, Ontologies and Rules for the Enterprise SCOPE The VORTE workshop will cover research topics relevant to description formalisms for enterprise application architectures, services, content and regulations. Regarding applied research, this also includes service description technologies for inter-enterprise collaboration like extensions to UDDI or OWL-S. Regarding fundamental research, this includes foundations and applications of semantic methods for enterprise object, rule and process modeling like those proposed in semantic web research. Moreover, recent research shows that semantic description formalisms can be integrated with a model driven architecture approach to business application development and deployment. This appears particulary interesting w.r.t. automated implementations of business rules and executable business processes. KEYNOTE ADDRESS Colin Atkinson, Chair of Software Technology at Mannheim University: Models versus Ontologies - What's the Difference and where does it Matter? As models and ontologies assume an increasingly central role in enterprise systems engineering the question of how they compare and can be used together assumes growing importance. On the one hand, the semantic web / knowledge engineering community is increasingly promoting ontologies as the key to better software engineering methods, while on the other hand the software engineering community is enthusiastically pursuing the vision of Model Driven Development as the core solution. Superficially, however, ontologies and models are very similar, and in fact are often visualized using the same language (e.g. UML). So what's going on? Are models and ontologies basically the same thing sold from two different viewpoints or is there some fundamental difference between them beyond the idiosyncrasies of current tools and languages? If so, what is this different and how should one choose which technology to use for which purpose? THEMES AND TOPICS The workshop contributions will be organized along three major thematic areas, under which these and topics of interest will be included ... * Model-Driven Architecture (MDA) approaches to Enterprise Computing * Modeling and Architecture Frameworks * Domain specific Business Information and Application Engineering * Modeling Enterprise Components * Conceptual Modeling * Business Vocabularies and Terminologies * Ontological Approaches to Content and Knowledge Management * Enterprise Information Integration and Interoperability * Taxonomies of Services and Service Registries (eg, UDDI related research) * Business Rules and Business Process Semantics * Semantic Web Services * Service Ontologies (eg, OWL-S related research) * Architectures for Business Rule Components * http://www.pms.ifi.lmu.de/mitarbeiter/spies/EDOCVORTE2006.html
