This is really only to give you an idea of what is possible with biblatex. It will not give you the output you want for other reference types. But with this as a starting point and looking through the file standard.bbx and the biblatex manual, you should be able to set things up as you need.

biblatex-sbl(though given the field, you don't want to use this). But it's similar tobiblatex-chicago. Inbiblatex-sblI made a custom entry type calledconferencepaper. The "summarized in" bit can be handled using a related entry. As @moewe has said, we need to know the biblatex style you are using before giving an answer. – David Purton Jun 28 '17 at 01:19biblatexnumeric style? Or something different/modified? a MWE with what you have so far would still be useful. – David Purton Jun 29 '17 at 12:06
