Work Breakdown Structure for the External Data Server Proof-Of-Concept

• The TODOs listed below were added to the EA block-diagram, look at ExternalDataServerPoC-WBS.pptx
• After addition of a description of work and definition of done to each TODO, these TODOs will be entered into Jira.

VSS feeder component

• todo finalize permissions layer concept (independent work item)
  
  • description TBD
  • definition of done TBD

• todo create a layer concept for the Franca to VSS leaf mapping (model transformation)

• todo design and implement franca service (SomeIP)

• todo implement feeder as PoC

• todo check signal to service translation in Adaptive Autosar

• todo agree on PoC use cases for the implementation

• todo create PoC Someip simulation component to playback agreed use cases
  
  • note: we could consider using an Adaptive Autosar node like what we did for the FARACON demo
  • note: VSS data base could be merged into the VSS feeder

• Select and implement feeder input API → how feeder writes data into the "shared database"
• Either it is writing directly into the database (shared with the VSS data server component) or writing into an API provided by the VSS data server. 

VSS data server component

• APP implement authentication to access the data server (eg JWT), e.g. json Web token
  
  • relates to Vehicle Signal Authentication
  • description TBD
  • definition of done TBD

• Implement the connection between the access protocol (GraphQL) and the fetching/writing of data into the database.

• APP implement request/response serialization
  
  • Gunnar: this is probably defined by the communication protocol (defined by GraphQL)

• todo resolve requested data for the APP from the VSS data structure

• todo change/write data values for requested data leaves
  
  • look at https://github.com/w3c/automotive/issues/322

• todo handle the subscription for APPs

• todo write a generator which will handle permissions in the data server
  
  • look at on-going discussion in W3C on the dynamic registry https://www.w3.org/2019/11/W3C_Gen2_dynamic_registry.pdf (Geotab proposal)

Framework Layer / Authentication Service

• todo request APP permissions from package manager
  
  • description TBD
  • definition of done TBD

• todo generate access token for the APP including the APP permissions

Application Layer

• todo Implement the APP permissions based on permissions defined/proposed in VSS layers
  • description TBD
  • definition of done TBD

• todo implement access token request

• todo APP implement request/response serialization for the client

• todo implement the selected use cases
