13:09:18 <Zakim> RRSAgent, make logs Public
13:09:19 <Zakim> please title this meeting ("meeting: ..."), mlagally
13:09:28 <mlagally> meeting: wot-uc
13:09:43 <mlagally> scribenick: cris
13:10:14 <cris_> topic: Publication
13:10:31 <cris_> ml: I've look into all the checks and warnings from the automatic checker
13:10:41 <cris_> ... it seems that we are not using the latest version
13:10:50 <cris_> ... we need input from kaz
13:11:12 <cris_> ... I hope to conclude the editorial changes for end of the week
13:12:04 <cris_> topic: PR
13:12:16 <cris_> subtopic: add service migration #186
13:15:09 <cris_> cris: update title, added two vertical use cases, add reference to WNIG
13:15:24 <cris_> mc: title might ok, it is just inconsistent
13:16:21 <Mizushima> -> https://github.com/w3c/wot-usecases/pull/186
13:17:48 <cris_> cris: add a monitoring a bridge scenario
13:18:20 <cris_> ml: what happens when handover fails
13:19:44 <cris_> cris: yeah good point, we laverage on the tool used for migration.
13:19:57 <cris_> ... the migration is a transaction
13:20:18 <cris_> ... either it succeed or it fails
13:20:30 <cris_> mc: I think it would be better to have names for those sections
13:20:42 <cris_> carlo: yes totally
13:21:19 <cris_> ... in the second use case there's an ECG device that monitor a worker
13:21:27 <cris_> ... that moves in a industrial plan
13:21:59 <cris_> mc: is there any distinct features of these two use cases
13:23:10 <cris_> carlo: pretty similar use cases
13:23:33 <cris_> cris: true but the first one is cloud-edge and the second one is edge to edge
13:23:36 <cris_> mc: got it
13:23:58 <cris_> ... they are indeed different, mostly because of the triggering conditions
13:24:30 <cris_> carlo: indeed in two there's a mobile component
13:24:43 <cris_> mc: there's also the issue of measuring the conditions
13:24:58 <cris_> carlo: true
13:25:26 <cris_> ... you may have different parameters to optimize
13:26:49 <cris_> ml: depending on the event model you run in to potential troubles
13:28:26 <cris_> cris: we had some experiments with events but they were just prototypes
13:28:56 <cris_> ml: in the profile spec there's an async action model
13:29:13 <cris_> ... when the action is pending you should block the migration
13:32:50 <cris_> cris: good point it depends about the situation you can do different techniques
13:33:10 <cris_> carlo: with our solution you can migrate the whole state
13:33:52 <cris_> mc: it is also something about requirements
13:34:07 <cris_> ... we are working on this in WNIG
13:34:53 <cris_> ... also security is something that should be taken into account
13:35:36 <cris_> ... you can put this as a Gap
13:36:05 <cris_> ml: why don't we call this use case Thing Container migration ?
13:36:29 <McCool> q+
13:37:53 <cris_> ... you have defined an interface
13:37:59 <cris_> ... for handling migration
13:38:38 <cris_> ... do you think it is worth having those as a standar API?
13:39:03 <cris_> cris: yeah I would say it would help reducing the fragmentation
13:39:51 <cris_> ml: do you think this can be model as a Thing
13:39:58 <cris_> cris: yes, we did like that
13:40:09 <cris_> mc: the Edge Worker implements something similar
13:41:32 <cris_> ... migration can be Application aware or transparent
13:41:47 <cris_> ... not sure if this is captured in the document
13:41:58 <cris_> cris: yeah we handling this
13:42:40 <cris_> mc: containers are not only way of doing this, we can use wasm too
13:43:00 <cris_> ml: should we introduce managment things?
13:43:15 <cris_> mc: it might be too premature
13:43:26 <cris_> ml: just a terminology
13:44:07 <cris_> mc: managment API is happing also in scripting API
13:44:43 <cris_> cris: +1
13:44:59 <cris_> mc: is that a thing or not really?
13:45:18 <cris_> ... do it have network interfaces?
13:45:26 <cris_> s/do/does/
13:46:04 <cris_> ml: do we have a better title now?
13:46:18 <cris_> mc: I am ok for merging
13:46:24 <cris_> ... I just have minor comments
13:47:19 <cris_> ... I would use just migration
13:47:27 <cris_> ml: between platforms
13:48:19 <cris_> mc: I would vote either for Migration or Thing Migration
13:48:51 <cris_> ml: ok we can merge it
13:48:57 <cris_> ... is a good contribution
13:49:07 <cris_> ... it triggers new discussion points
13:49:45 <cris_> mc: I'm working a lot in this problem too
13:51:05 <cris_> cris: when and where will the TD for Edge Workers be published?
13:51:20 <cris_> mc: I don't have it yet, we are looking for requirements
13:51:38 <cris_> ... finger printing, packages, binaries
13:51:51 <cris_> ... alibaba is working there
13:52:19 <cris_> ... we are working on getting Microsoft, Google on board too
13:54:40 <cris_> ml: it is really difficult to consistently migrate microservices
13:54:50 <cris_> mc: live migration is really challenging
13:54:59 <cris_> ... application migration is way eaiser
13:55:11 <cris_> s/eaiser/easier/
13:55:40 <cris_> ml: ok going back to the PR I'm ok for merging
13:56:28 <cris_> ... merged
13:56:30 <cris_> ... aob ?
