4. Follow-up on OData for MCP [8:15]

   1. Transcript attached

   2. Upload Video Somewhere? (781MB)

      Mike will share it (on his OneDrive) and send out a link.

   3. Possible next steps

      1. Create an OData to MCP Mapping Committee Note

         There is general interest in this topic. How much does an LLM need an MCP service to guide it towards making requests? How can data aggregation be represented?

      2. Reference from Rapid.Rocks

      3. Add sample to Rapid.Rocks

      4. Other?

      TC does not plan any next steps at the moment.

5. Progression of Aggregation Extensions to CSD05 [8:45]

   Heiko will prepare a separate branch of the OData vocabularies that omits data-aggregation-related terms that are only needed for CS03 but not for CSD05. A new zip file for public review will be presented in the next meeting.

6. Issues [9:30]
   OData TC Github Issues

   Missing odata. prefix #2121
   The 4.0 example before the one mentioned in the PR also wrongly uses @odata.id instead of id in a deleted-entity object. Heiko augments the PR accordingly.
   Heiko moves to merge the augmented PR. Hubert seconds. No objections, motion passes.

   Interdependent DELETE requests in a change set #2103
   Mike proposes a resolution and will prepare a pull request that clarifies the delta payload case. TC agrees that the spec allows a 204 response for a DELETE request on a non-existent resource and sees no need to change the text of the spec to make this clearer.
