It looked to me like the Eddystone method relies upon the Google cloud?


The RWW method sought to provide independence as an alternatives?

I note various linked-data-notifications related works,

But is what you're saying mean I'm misunderstanding the Google offer? I
hadn't confidently found a solution that was independeny, which I blamed on
the lack of a RWW like solution to plug it into...

The owner of the device would need a standards based place to store the
data / telemetry, et.al. then, I envisage, support ontology orientated
accessible factors...

Re: bootstrapping, agreed.  Perhaps simpler than doing something similar by
loading-up Ubuntu and solid-node-server, to test an alternative POC... ;)

I was planning to get a raspberry PI, adding some solid-state relays and
