12. SWWS approaches… combine the information infrastructure provided by RDF and RDFS either with the higher-level ontologies or lower level web service technologies modeling hierarchical domain ontologies, improving web service components with RDF or using intelligent data itself other research platforms and developed tools like KIM, S- Cream, KAON and Knowledge web (previously OntoKnowledge project) http://swws.semanticweb.org

13. Industrial semantic web Vagan Terziyan: Industrial Ontologies Group (IOG) in the University of Jyväskylä, Finland usage of semantic web and web service approaches in industrial software development current semantic web applications and application development using existing tools and platforms http://www.cs.jyu.fi/ai/OntoGroup/index.html

14. OntoServ.Net concept from IOG Applied SW and web service usage to business domain areas like industrial maintance open issues on semantic web versus low level information exchange in the wider scopes of EAI and e-business scopes in general: SOAP needs semantics “injected” or RDF and “mediation” of ontologies

15. Industrial software development Low level data approaches with IT vendor frameworks (like Java technologies or Microsoft.NET): plain XML, SOAP and RDF usage IOG approach: domain ontologies and RscDF, OntoNet approaches with GUN framework SW modelling: domain ontologies SW applications: Software infrastructure: WS Information infrastructure: RDF, RDFS Basic platforms for web based data communication: HTTP, XML, SOAP based data

16. CONCLUSIONS Example of semantic web usage and development In general, semantic web services are harder to build compared with web service build plainly on SOAP Low granularity in the logic of RDF that has been in-built in the business process focused web service codes
