  • Gunnar: data categories and data contracts is rather a tool than a result, relates to access control, this topic is also being discussed in W3C
  • Ulf: we are talking about data categorization and VSS layers but I cannot see the link between both
  • Gunnar: there are 2 ways of representing the categories in the layer concept, VSS layer is a format to represent the data categories
  • Ulf: discussion data catzgorization is different from representing the categories for instance using the VSS layer data format
  • Gunnar: access control group is one example of data category (TBC)
  • Gunnar: data contract is something different
  • Ulf: it is a fuzzy concept for me
  • Gunnar: I can see the connection, I need to check the Geotab's presentation in W3C team about it
    • the presentation is available there
  • Gunnar: we need to have common terms on contracts, technical and commercial parameters
  • Rex: when you talk about QoS, do you have in mind protocols like DDS and Some/IP (signal-to-service), ARA::COM, some of the building blocks may be there
  • Philippe: asks Rex to review the signal-to-service requirements in ARA:COM
  • /TODO/ Philippe send to Rex the Adaptive Autosar signal-to-service specification DONE
    • look for the following requirements: RS_CM_00004 in RS, and 7.5.2 in SWS (the SWS section is the significant reading)

  • Ulf: who are the two parties in such a contract discussion ?
  • Gunnar: could be the OEMs and the neutral server companies
  • Kevin: data providers = OEMs,  there is a contract between the neutral server and the third parties (data consumers), the neutral server does not change much the content
  • Gunnar: we need a framework / template to write those contracts
  • Gunnar: we need to set up a framework for access control
  • Kevin: applying data categories to data contracts is the real pain
  • Gunnar let separate those two wordings and check whether the industry wants to progress on both topics
    
    • /TODO/ Gunnar structure better the Jira ticket in order to distinguish the work on data contracts from the work on data categories

  • Glenn: data contracts in Geotab document mentioned above might not fully be appropriate for the discussion we have here
  • discussion on what a contract is all about
