I see no "holy war", certainly not like those in the past and I was there for them. Business Object Models are deprecated in ISO 10303-1e3 and replaced with Domain Models specified in SysML (v1), the ISO 10303-242 one will look very similar to the current BOM and will have alternative EXPRESS and XSD representations. The SysML Canonical XMI files that are the specification of the standard will be provided with it, a user can use the tools I linked to in order to convert this to something that can be loaded into a SysML editor. Someone using ISO 10303 EXPRESS models now can carry on using them in the future, there isn't some change they are forced to adopt. The only real user visible difference will be a more complete mapping between a Business Object Model/Domain Model and the traditional EXPRESS Application Protocols. I am maintaining Express Engine and adding new features, I'm not the original author though.
