However, this Meta block in the DDMS content schemas does not contribute to the "normalization" of any units of measure in the RAFS DDMS. The RAFS DDMS does not today do unit of measure normalization. (If normalization is needed today, it can be done by the consuming application.) It is possible that in the future, the RAFS DDMS will do unit of measure normalization like the Core Services do with catalog schemas; That question is under discussion at this time.
Note that we expect to deprecate specific frame-of-reference blocks from the RAFS DDMS content schemas, in the post-M25 timeframe - namely `FrameOfReferenceCRS` and `FrameOfReferenceAzimuth`, since we never expect these to be used in the data content in the future; These would only be used the metadata/catalog, and they are already present there.
You can read more about how the catalog schemas using this "meta" block and how it relates to normalization in the OSDU Core Services [here in the OSDU Schema Usage Guide](https://community.opengroup.org/osdu/data/data-definitions/-/blob/master/Guides/Chapters/04-FrameOfReference.md)(Frame of Reference section).
### 13. Does the RAFS DDMS store its content (Parquet files) in the OSDU generic/core storage or the RAFS DDMS's local storage?
