RE: Actuation and Actuators in SOSA (issue-91)

Raul,
This seems to be richer than anything we have discussed yet. I wonder whether you would be interested in proposing how to model this in ssn that can afford to be that rich? I don’t' think anyone in the group  is working on that already. But Maxime might have started on it. We have our own use  cases of course, but straying into the WoT uses cases as well could certainly help us too. 

Danh is also working with the WoT group   -- maybe Danh could help with this? 

> We can align with their terminology using: Actuator, Action, ActionableProperty.

Suits me. 

And if we have something to offer we should make sure we communicate that back with the WoT group.

Thanks very much for doing this background work.

Kerry

Hi,

In the Web of Things IG, three interaction patterns (involving data
interchanges) have been defined (not in any specification):
https://w3c.github.io/wot/current-practices/wot-practices.html#interaction-patterns


* Property (readable and/or writeable data)
* Action (changes or processes on a Thing that take a certain time to
complete)
* Event (mechanisms to be notified by a Thing on a certain condition)

We can align with their terminology using: Actuator, Action, ActionableProperty.

Also, related to the discussion on what is the result of an Actuation, such result will depend on how the interaction is designed. I quote from the same document: "Usually, invoking an Action results in a response that indicates a new (sub-)resource, where the started Task can be monitored and also controlled".

Kind regards,
