 ### 4. Are the OSDU Data Definitions Schemas (Well Known Schemas / WKS) ready, in order to support the RAFS DDMS?
 
-As of December 2024, most of the WKSs are ready. There is, however, some clean-up to be done to deprecate old schemas, and consolidate certain reference lists. That clean-up is captured in [this Gitlab Issue (Petrophysics 62)](https://gitlab.opengroup.org/osdu/subcommittees/data-def/projects/Petrophysics/home/-/issues/62).
+Update Feb. 2026: The clean-up previously mentioned is nearly completely done and documented. See the following for details:
+
+* [Schema Usage Guide Chapter](https://community.opengroup.org/osdu/data/data-definitions/-/blob/master/Guides/Chapters/12-RockAndFluidSampleAnalysis.md?ref_type=heads)
+* [Change Report M26.0](https://community.opengroup.org/osdu/data/data-definitions/-/blob/master/Guides/Chapters/12-RockAndFluidSampleAnalysis.md?ref_type=heads)
+
+The remaining clean-up is to capture Top Depth and Base Depth on `master-data--Sample` independent of the sample acquisition depths (see [DD Petrophysics Issue 147](https://gitlab.opengroup.org/osdu/subcommittees/data-def/projects/Petrophysics/home/-/issues/147).
