13:11:40 <ktk> +1 on this idea from kaz
13:11:47 <mahda-noura_> david: question on the discovery, are you creating a catalogue for devices, could change the industry, would be an opportunity for wot to create a schema.org
13:12:36 <cris_> q?
13:13:27 <mahda-noura_> kaz: my poiny is simply, when we say HA with WoT, what are existing HA mechanisms are to be discussed here?
13:13:42 <mahda-noura_> ege: wot would be another button added to the HA
13:14:11 <mahda-noura_> kaz: do you want a new home assistant framework with WoT?

13:18:43 <cris_> q?
13:19:32 <mahda-noura_> ege: for manufacturers, they can write TDs for their devices and allow the gateway to discover it
13:19:41 <aciortea_> aciortea_ has joined #wot-home-assistant
13:20:27 <mahda-noura_> adrian: can you show the northbound code again, I think this goes in the direction of what I mentioned, HA is weak in terms of semantic, and if we can find people who can contribute, and enable people to add the semantics
13:20:48 <mahda-noura_> ege: what would be good semantic technologies
13:21:24 <mahda-noura_> adrian: I would make cubes and write it in a triple store, and could migrate my use cases

13:24:08 <Robert_Winkler> At DT we integrated hundreds of devices via WoT. It might make sense to align on a common semantic schema for Smart Home devices with Home Assistant and learn from eachother.
