PatrickL: what we had in mind this week was summer homework from the convergence overview list
https://www.w3.org/auto/wg/wiki/VISS-RSI-convergence-framework#TO_DO
PatrickL: next three weeks are
off
... addressing is one area I want to focus on. goal would be
able to address signals even from a distributed service
Adam: different issuers
PatrickL: yes, previously you will need to address a data element somewhere in the vehicle network
Laurent: like someone wrote in email thread, ability to cross between VISS and ViWi services
PatrickL: not completely clear yet but we want to bring in more things from ViWi world into VISS
Laurent: Ulf makes some excellent
points in his message
... not sure we can standardize on a tree yet
PatrickL: I think we can there is point versioning on the data model
Laurent: instead of adding
another MQTT syntax I would be inclined to use
... notion of path handled as are wildcards. it has other
advantages
... there is a very natural mapping between MQTT and VSS
tree
... you can reuse the payload and to me it makes sense to stay
close to something already defined
... so yes, let's focus on addressing :)
PatrickL: API version handling is something that should be worked on including how a service can handle multiple versions
<LaurentC> http://www.steves-internet-guide.com/understanding-mqtt-topics/
PatrickL: also registry
Laurent: that getMetaData
PatrickL: yes part of
addressing
... we would want one style for the developer to be able to
handle one protocol type
Laurent: how the registry is populated is prioprietary, all we we cover with scope of our work is defining how third party developers can find services
Ted: would OEM allow after market services to be added to their vehicles? agree with Laurent, we are more on the client end
PatrickL: I see adding a service as no different from adding an application, enabling functionality on vehicle
Laurent: there are security
considerations
... media service is a good example but if it is not certified
than there is no point, it won't be trusted
PatrickL: changing radio station and adding a service that brings in new media is no different
Laurent: we are close to allowing
limited apps in car. this is feeling like quite a bit of
work
... would it prevent OEM from their own proprietary
registries?
PatrickL: registry, addressing and api versioning the three topics Laurent and I will look into the next three weeks and send to the list
Ted: I'll delve into addressing as well
PatrickL: adjourned, see everyone in four weeks
