1 Definition
The Action of a User requesting that Location Service:
- Move an MU-Added R-Item from a Point of View to another Point of View via a Trajectory.
- Grant Rights to the MU-Moved R-Item based on requested Rights.
If the request is accepted, the Export Service moves the R-Item to the new U-Location with the assigned Spatial Attitude via a Trajectory and grants the requested Rights to the R-Item.
Note: the U-Location client of the Export Service converts the original and destination Spatial Attitudes, and the Trajectory into a Stream that moves the R-Item to the destination U-Location. If no Trajectory is provided, the Export-Import Service or the R-Item organise the movement from the source to the destination U-Location.
2 Protocol
- User sends “MU-Move PA Request including R-Item, Point of View1, Point of View2, U-Location, and Rights (Status=Model)” to MU-Move Service.
- If MU-Move Service is a free service, goto MU-Move.
- If MU-Move Service is a pay service:
- User sends “MU-Move PA Request including Service Pricing Model (Status=Model)” to MU-Move Service.
- MU-Move Service sends “MU-Move PA Response” to User:
- If “MU-Move PA Response includes Status=Err”, goto End
- If “MU-Move PA Response includes Status=Ack and Service Pricing Model with Transaction (both Status=Model)”, User
- Transacts “Value included in Transaction”.
- Sends “MU-Move PA Request including Service Pricing Model (Status=Model) with Transaction (both Status=Final)” to MU-Move Service.
- MU-Move: MU-Move Service:
- MM-Moves “R-Item”.
- Sends “MU-Move PA Response” including
- “Rights (Status=Final)” to MU-Moved R-Item.
- “Service Pricing Model (both Status=Final)”, if MU-Move is a pay service.
- End.
