Question 2

Choose the correct answer
What is the key distinction between SysML modeling and MOF modeling?

• A. MOF models are used for domain-independent modeling SysML models are used for domain- specific modeling.
• B. MOF models are intended to be models of modeling constructs SysML models represent real world entities and processes.
• C. MOF models are intended to be strictly models of abstract entities SysML models represent real world entities and processes
• D. They both have the same purpose except that MOF modeling is intended for specialized and advanced usage by systems architects

B.
Define and apply appropriate profiles

C.
1) Define one common set of SysML elements for all stakeholders.
2) Create a package structure that covers the relevant aspects
3) Set up model access rights (readVwrite/delete) for the different stakeholder groups
D.
1) Define viewpoints for the different stakeholder concerns and set up conformant views
2) Set up model access rights (read/write/delete) for the different stakeholder groups
