We have a schema for Oem shared by our coworking partners and find there's a URL without "/Oem/Ami" (screenshot 1). We also find the definition for Oem in Redfish spec (screenshot 2) asking us to contain /Oem/<OemIdentifier>/ in URL.
Want to check if the schema is valid, thanks. . screenshot 1 . screenshot 2 (from DSP0266_1.15.1.pdf)
