16:25:53 <thjaeckle> mm: examples in the wild: multi sensors and power outlets

16:26:44 <thjaeckle> mm: multi sensors is probably a more common example
16:27:49 <thjaeckle> sk: a room could also be a TM and could have different submodels in there
16:28:00 <jkrhb_> q+
16:28:12 <thjaeckle> mm: a room is more of a location consideration
16:29:12 <jkrhb_> q-
16:29:18 <thjaeckle> sk: example from last test fest: a line which contains multiple machines as submodels
16:30:32 <thjaeckle> mm: multiple power outlet strips is also a good use case to consider how to model that
16:31:28 <thjaeckle> mjk: brings up also LED strips example
16:35:17 <thjaeckle> mm: the point is that for an outlet strip, you reference one defined submodel outlet several times in the top TM
16:36:06 <thjaeckle> mm: examples for both, multi sensor use case and mutliple power outlet strips, would help
16:37:03 <thjaeckle> sk: asks for the oneDM light strip example
16:37:40 <thjaeckle> sk: let's go for a more clear example

16:40:09 <thjaeckle> -> https://github.com/w3c/wot-thing-description/pull/1254 allow type to be an array
16:40:31 <thjaeckle> ek: this breaks backwards compatibility
16:40:57 <dape> q+
16:41:01 <thjaeckle> sk: we should do a new PR reverting that
16:43:05 <thjaeckle> ek: array of types was intended as a basic "one of" construct
16:44:06 <thjaeckle> dp: is it intended to be possible in TD 2.0?
16:44:24 <thjaeckle> ek: from his point of view: yes - should be possible in TD 2.0
16:44:55 <thjaeckle> ek: will provide PR reverting that change
16:45:58 <thjaeckle> sk: Ege can merge directly to have it available in WD
