PR 707

PR 707 - Draft Implementation Report

McCool: suggest we merge this PR, and I and Fady will work on further updates
… my tool collaborating with his one
… have to fix some strange issues with the CSV files, though
… will check the categories, etc.

Lagally:: perhaps you could delete wrong parts?

McCool: caused by the tools

Lagally:: when would we be ready?
… CSV results, testimonials, ...

McCool: will clean it up

Lagally:: ok
… we still need another round
… let's visit this next week then

McCool: ok

PR 711

PR 711 - Definitions for Device, Service, etc.

McCool: definition for device, etc.

diff - 3. Terminology

McCool: regarding "Digital Twin", one actual physical device and virtual thing

Lagally:: (shows "Virtual Thing")

McCool: a service representing the functionality of a Thing

Lagally:: a bit overlap with shadow

Kaz: good starting point
… but a bit complicated, e.g., about "Virtual Thing"

McCool: yeah
… but not ambiguous

Lagally:: ok
… let's merge this
… and we can add further improvement if needed
… (then shows the Editor's note for "Partial TD")

McCool: producing method for more details
… we should check if the definition is true

Scripting API Note - 5.2 The produce() method

McCool: there are mandatory things which are not specified by the spec

Lagally:: will create an Issue and assign it to Daniel as the Scripting API Editor
… (creates a new issue)

<mlagally_> Issue 714 - Outdated note on partial TD ?

Lagally:: (going back to the Terminology)
… TD Fragment
… (another Editor's note there)

In JSON representation it must be a valid JSON document, however could
be just an inner structure omitting outer elements, curly braces etc.
present in a full TD. As a use case the TD Fragment is useful for
Discovery results returned by a JSON-Path query. See the WoT Discovery
specification [ WOT-DISCOVERY ] for more details.

McCool: my preference leave it out

Lagally:: (creates another new issue)

<mlagally_> Issue 715 - Verify note on TD Fragment

Lagally:: let's merge PR 711 itself now

(merged)

PR 712

PR 712 - Terminology diagram as worked out on the Architecture call on Feb 17th

McCool: let's merge this

Lagally:: if somebody has time, would be good to update it

McCool: is that an SVG file?

Lagally:: yes, SVG

(merged)

PR 704

PR 704 - restructuring lifecycle section

Lagally:: not really readable yet...

diff - 7.4 Lifecycle

Lagally:: let's look at the rendered version

preview - 7.4 Lifecycle

Lagally:: (goes through it)

McCool: typo with "becomer"
… reviewing the lifecycle diagram is on the tray of the Security TF as well
… I'm OK but the TF should review it again
… none of the diagrams are inconsistent with the previous discussions
… one thing not mentioned is security
… Security TF to review the section and think about additional description
… not wrong but stuff it out

Lagally:: absolutely
… section structure to be fixed, though
… (for "Thing Lifecycle", etc.)
… will fix it
