Hi @M-Dev
The metadata tags such as vti_replid and vti_rtag that are not described in the documentation are not necessary for interoperability. Your tool only needs to preserve them on write to successfully interoperate with SharePoint. If you find that you do need those fields to interoperate with SharePoint or they’re needed for your tool to function, please provide the specific fields needed and an explanation as to why these are needed, and we will work to define them.
For more information about how SharePoint handles metadata and which metakeys are documented, please see MS-FPSE 2.2.4.
Best regards,
