Unfortunately, not very helpful.
The first and third links you provide do not discuss or reference the cmdb_software_component_model table in any way that I can see.  Can you elaborate on why you think these links have some to do with the cmdb_software_component_model?  What am I missing?
Your third link is the same link I used/posted in my question 3 times.  😕

The final link is somewhat helpful; Suryakiran mentions its use in relation to using DPR for developing a release.  But there is not a lot of detail, or discussion in relation to SAM which is what I am after.  I will reply to Suryakiran's reply in hopes they can help with the details.
