We want to add semantic annotations only. 07:01:30 s/JSON/JSON Schema 07:02:14 Sebastian: we define Events, Properties, Actions in TD and rely on JSON Schema for Data Types 07:03:57 McCool: we have to define vocabulary in advance to enable contained IoT device to handle them. But for different domains/devices we need multiple schema - this complicates things. 07:04:21 q+ 07:04:33 Victor: in addition two devices may use different vocabularies even for the same domain. 07:04:51 present+ Zoltan_Kis 07:05:18 present+ Achille_Zappa, Ari_Keranen 07:05:40 Victor: we should not enforce one schema/one structure only, need to be flexible. 07:06:21 q? 07:06:35 McCool: I suggest we stich to JSON as the mapping to other formats can be made. 07:09:00 Sebastian: this will be one of the major topics in the upcoming F2F meeting in Osaka.
