Om een canoniek dataobject (= Noun) te kunnen gebruiken in een bericht, wordt er een schil omheen gelegd waarin oa het type bericht staat aangegeven. Bijv. NotifyOperatorOrder of ProcessMasterEmployee. EDM volgt daarbij de standaard van de Open Applications Group, zie bijgevoegd document.
Doel van dit document volgens de Open Applications Group:
"The Open Applications Group Integration Specification (OAGIS) provides a canonical business language for vertical industries. Individual organizations and entire supply chains may further extend the specification in ways that meet their own unique needs. It is important for OAGi to define the naming, design rules and guidelines used for OAGIS in such a manner that these organizations may follow them for their extension.
This specification provides a means to identify, capture and maximize the re-use of business information components within OAGIS and OAGIS extensions in order to support information interoperability across integrated environments.
