Creating Data models in local ER studio environment

I'm working on data models for wells and subsurface.

We have our data models is ER studio. I am trying to recreate the OSDU equivalent in our ER studio environment for comparison. The idea is it will support modelling and analysis of the complex migration.

I have imported the relevant JSON file for Well 1.1.0 to create a draft diagram in ER Studio.

However, it doesnt match the full data listed in the ODSU repository mark down files. I believe is doesnt import the numerous abstract files.

I guess I am looking for a bit of guidance on whether:

Its possibly to get the source OSDU ER studio file for Well 1.1.0 (or latest version) Some guidance on how to re-create it (in our environments) from the md or JSON files. Whether its a non-starter due to the complexities of well 1.1.0 (i.e. lots of abstract classes in different files etc).

Many Thanks. My apologies if this isnt the correct forum.
