### 10. In early versions of the RAFS DDMS, there was an endpoint called "PVTModel". That endpoint had associated custom catalog/WKS schemas and DDMS content schemas. As of Feb. 2025, why were that endpoint and those custom schemas removed from the RAFS DDMS?

When the RAFS DDMS was in its experimental phase (2022-2024) and when the Data Definitions team was working on the "unified" sample data model, nearly all schemas used by the RAFS DDMS were custom and preliminary. As the Data Definitions data model evolved and the scope for a mature RAFS DDMS was solidified, many of those preliminary custom schemas were removed from the RAFS DDMS and replaced by published and approved schemas. PVT Model and related schemas were not removed until Jan./Feb. 2025, as the last vestiges of those temporary custom schemas.

There was little to no value in keeping this endpoint and these schemas, so in late January, early February, 2025, they were removed from RAFS DDMS v.2.

To be clear, "PVT Model" is _not_ the same as "PVT Analysis". "PVT Model" is another name for, or a component of "Fluid Model".
