[MW] Unfortunately, this is not what ontological 4-dimensionalism
is about. Can I suggest you take a look at a presentation I made
at Leeds University "An introduction to 4-Dimensionalism in data

taModels.pdf     (02)

On my "Recommended Reading Page" you will find references to 
books that give a more thorough coverage.

In particular Hawley and Sider.    (03)
