REA ontology; Enterprise ontology; DEMO; Co-creation; Co-production

Co-creation and Co-production in production chains is the typical way of cooperation one observes in high value industrial production chains. The enterprises in these production chains constitute together also a sophisticatedvirtual enterprise. While many professional IT systems are operational within these enterprises, there are only IT technologies with a limited scope at a small scale available between these enterprises. The new technologies currently provided by enterprise engineering promise substantial operational improvements;operational control, compliance to business rules, optimization of efficiency andeffectiveness. Another objective is support for the REA ontology for high quality financial information systems, which requires a conceptual mapping between REA and DEMO to be found. The first step, a generic DEMO modelfor co-creation and co-production, has been devised and subjected to early validation.
