[Discovery] Use cases for the discovery task - revisited

Hi all,

I posted a new issue [1] related to the task of discovery. As we would like to provide thing discovery based on semantic annotations from thing’s TD, the question is what use cases shell be considered. The WoT Current Practices already assume three use cases [2], but to better understand possibility for semantic-based discovery it would make sense to revisit them.
Any comment or thought will be helpful.

Cheers,
Darko
