Definitely to be looked at for one of the outer cores. I don't think we need to distinguish between streams and discrete sensing in the core, though 21:43:44 q? 21:45:20 So this is an use case example of the current SSN? 21:48:18 q? 21:48:19 this is potentially a "horizontal" - scope extension of the "core modules" - do we mean a single module as core or the modularised set of concepts in scope? 21:48:21 q+ 21:48:36 ack KJanowic 21:49:35 jano: should be an extension to ssn and not in eithe the core nor the ssn namespace or it will be impossibel to mangage 21:49:41 q? 21:50:30 +q 21:50:34 q? 21:50:42 ack SefkiKolozali_UniS 21:50:49 Sefki: looks interesting to me but mostly as one of the many, very important cases that use or import or rework SSN but we should not take use cases and make them part of the standard 21:53:45 q? 21:53:52 IMHO, a standard has to be a subset of user requirements, not a super set. 21:54:57 q+ 21:55:05 ack SimonCox 21:55:25 I believe that sao:point and sao:segment are fairly crucial to ingerate into the ssn or to use on iot devices as it allows one to represent data streams in temporal features when we conduct time series analysis 21:56:38 q? 21:57:49 issue: should sao"point and sao:segment be inside the core for time series analysis 21:57:49 Created ISSUE-71 - Should sao"point and sao:segment be inside the core for time series analysis.
