Digital asset, Spatial mapping and Spatial anchors server - Service Enabler Architecture Layer for Verticals (SEAL); Protocol specification;
The present document specifies the protocol aspects and APIs for the metaverse application over the 3GPP network for SAn-UU, SM-UU, and DA-UU reference points. The APIs are specified as RESTful APIs except for custom operations wherever required.
The present document is applicable to the user equipment (UE) supporting the digital asset as described in 3GPP TS 23.438 [3], spatial mapping and spatial anchor client functionalities as described in 3GPP TS 23.437 [2], to the application server supporting the digital asset as described in 3GPP TS 23.438 [3], spatial mapping and spatial anchor server functionalities as described in 3GPP TS 23.437 [2] and to the application server supporting the vertical application server (VAL server) functionality as defined in specific vertical application service (VAL service) specification.
NOTE: The specification of the VAL server for a specific VAL service is out of scope of the present document.
