McCool: makes sense

<Ml shows the diff of this PR>

<kaz> 11 Security Considerations

<kaz> 12 Privacy Considerations

Lagally: what is new?

McCool: trusted envorenment and some sections have to be rewritten

Kaz: the descriptions are relatively stable. also the PR will change the section structure. so I'd suggest we once merge this PR and add further improvement after that.

no

Improve chapter headings #694

PR 695

<kaz> PR 695 - fixes #688: Improving language, adding rfc2119 assertion

<kaz> diff in "7.1.3 Links"

Lagally: update e.g. text about the Links

Ege: I would use other JSON-LD description for geofance and TD reference to it

Lagally: how many reference would I need then?

Ege: if everything is in the TD I would always need semantic processing
… you not solving the problem when you have everything in the TD

Ege: is there as example no_sec for security it does not mean there is no security at all

McCool: we don't have any requirements that everything needs to be a "Thing"
… Things may have network interface and additional metadata

Ege: promoting this approach might make things diverse

Kaz: think we should think about hardware layer and software layer separately when we think about use cases

Lagally: yes

<Mizushima> +1 kaz

Lagally: WebThing has a network interface
… we should split physical layer and abstract layer
… let me type in

<mlagally> proposal: split terminology "Thing" and "WebThing"

<mlagally> Thing being the general form which may only have metadata.

McCool: I'm working on a PR about terminology, btw

Lagally: tx
… talk to you soon!
