13:11:46 <Yingying> Sebastian show the slides for plugfest logistics.
13:12:28 <Yingying> Sebastian: it was agreed to have th preparation day one day before the plugfest. It will be Jan 24th.
13:12:40 <Yingying> ...this is the plan for next plugfest. any questions?
13:12:47 <Yingying> [no]
13:13:09 <Yingying> Sebastian: it was on wiki page as well.
13:13:40 <jhund> wiki page: https://www.w3.org/WoT/IG/wiki/F2F_meeting_2016,_January,_26th_%E2%80%93_28th,_France,_Nice#PlugFest
13:14:00 <Yingying> Sebastian shows the wiki page for plugfest plan.
13:14:37 <Yingying> Sebastian: you need to input your name, your application that you would show. I just copied the table from last plugfest.
13:14:49 <Yingying> ...please everyone put your information on it.
13:15:20 <Yingying> Sebastian shows the slides for the plugfest proposal.
13:15:58 <Yingying> ...1st proposal like in Sapporo, using TD to some thing discovery;
13:16:12 <Yingying> ...2nd, to cover the security aspect.
13:16:30 <Yingying> ...3rd we need some API on Things.
13:17:05 <Yingying> ...4th, from the joint meeting with IRTF, use PlugREST.
13:17:16 <Yingying> ...I need some volunteers to write some howto.
13:17:24 <Yingying> ...what we need to do in the plugfest.
13:17:49 <Yingying> ...I am asking Darko, Oliver, Daniel, Suomya to help.
13:17:57 <Yingying> ...I will do the first one.
13:18:33 <Yingying> ...The 1st idea is how we use the TD to do central-based discovery.
13:19:10 <Yingying> ...an example: We have down here different kinds of things.
13:19:19 <Yingying> ...each of them has a TD.
13:19:30 <Yingying> ...upper layer we have TD repository.
13:19:38 <Yingying> ...then we have one kind of client.
13:19:49 <Yingying> ...it is able to request some kind of TD.
13:20:02 <Yingying> ...How does it look like in interaction?
13:20:15 <Yingying> ...The thing is going to do the thing registration.
13:20:27 <Yingying> ...to the TD repository.
13:21:08 <Yingying> ...in the client slide, open source project, which you could download it.
13:21:43 <Yingying> ...2 ways to do registration: one is thing does it by itself; others to do it.
13:21:58 <Yingying> ...the major goal is to have different TDs in the repository.
13:22:22 <Yingying> ...there is a client to look for different kind of things.
13:22:41 <Yingying> ...the idea is the TD repository will provide different TD.
13:23:21 <Yingying> ...need to do how-to on the TD.
13:23:37 <Yingying> ...it will be on the wiki page of W3C in following days.
13:23:46 <Yingying> ...Darko, do you want to share yours>
13:24:03 <Yingying> Darko: idea is to provide how-to.
13:24:13 <Yingying> ...this is very preliminary docs.
13:24:38 <Yingying> ...I will show you how the docs will be like and get your comments.Currently it's incomplete yet.
13:25:08 <Yingying> ...Here I summarized what this repository can be used for. It can be used by human and things.
13:25:32 <Yingying> ...It is also possible to discover certain things based on TD.
13:25:59 <Yingying> ...invoke actions on certain things.
13:26:18 <Yingying> ...can create, delete TD from repository.
13:26:40 <Yingying> ...currently we have the reading and querying functionality.
13:27:15 <Yingying> ...if you want to query repository, you need to provide some data like this: URI, IP address, etc.
13:27:40 <Yingying> ...there is a payload example.
13:27:54 <Yingying> ...This is a kind of response to the query.
13:28:16 <Yingying> ...This is a JSON-LD file.
13:28:42 <Yingying> ...for others like updating or deleting TD, we will fill in.
13:29:25 <Yingying> Michael: Resource directory is exactly the same as your repository in our state machine partner.
13:30:09 <Yingying> ...Hypercat, SPARCL also used.
13:31:04 <Yingying> ...resource directory also has some basic query.
13:31:12 <Yingying> Darko: will you join us on this work?
13:31:42 <Yingying> Michael: sure.
13:31:42 <Yingying> Darko: we will communicate this how to with you.
13:31:56 <Yingying> ...we will work together to make examples.
13:32:30 <Yingying> Sebatian asked Oliver to show the security part.
13:35:02 <michael> Resource Directory; https://tools.ietf.org/html/draft-ietf-core-resource-directory-05
13:35:06 <Sebastian> less than 8 weeks remaining
13:36:01 <Sebastian> Oliver: add secure communications  but do not limit security  enabling to that
13:36:11 <DarkoAnicic> s/SPARCL/SPARQL
13:36:26 <michael> Oliver: Security proposal to adopt IETF ACE Working Group Architecture
13:36:43 <Sebastian> ... focus on authorizing and authentication
13:37:00 <Yingying_> Yingying_ has joined #wot-td
13:37:28 <Sebastian> ... add AM and AS components to the plugfest
13:38:21 <Sebastian> ... runs in a less constrained environment
13:38:51 <Yingying_> Yingying_ has joined #wot-td
13:39:25 <Sebastian> ... there will be also a HowTo
13:39:57 <Yingying_> nick: yingying

13:40:07 <Yingying_> nickname: yingying
13:40:09 <Sebastian> ... also a cheat sheet
13:40:52 <Sebastian> ... running AM and AS instances (provided by Siemens)

13:48:09 <yingying> Oliver: tomorrow we will look at this same thing but more details.
13:48:16 <michael> Oliver: Will discuss more tomorrow in the SP call
13:48:54 <yingying> ...we can bring it to life by end of next week.
13:49:23 <yingying> Sebatian: we have also another TF which concentrates on API.
13:49:48 <yingying> ...Daniel will also give some first idea.
13:50:05 <yingying> ...how the API would look like in next plugfest.
13:50:33 <yingying> Daniel:it's as mature as security.
13:50:42 <yingying> ...idea is to use WebIDL.
13:51:35 <yingying> ...we also will provide javascript API.
13:51:51 <yingying> ...encourage to try out other languages.
13:52:03 <yingying> ...feature based on previous plugfest in sapporo.
13:52:50 <yingying> ...WebIDL and Javascript API will be provided by end of next week.
13:53:17 <yingying> ...I can shortly show the javascript API made in september.
13:53:41 <yingying> ...very simple API that allows you to set or retrieve properties.
13:53:58 <yingying> ...in addition, there will be a howto provided once the APIs are shared.
13:55:29 <yingying> Michael: is the WebIDL machine-readable
13:56:18 <yingying> Daniel: WebIDL is just to provide the methods like prevously javascript APIs provide.
13:56:47 <yingying> Michael: it's the standardized format of scripting APIs.
13:57:10 <yingying> ...there will be a WebIDL coming along with TD for everyone to use. Cool!
13:57:37 <yingying> Johannes: WebIDL is that W3C uses to describe the APIs.
13:59:36 <yingying> Michael: just wondering general description for general interaction pattern.
14:00:19 <yingying> Sebastian: last topic is plugREST.
14:01:16 <yingying> Matthias:this is the so called plugREST by IRTF.
14:01:40 <yingying> ...background info is IRTF is the counterpart of IETF.
14:02:06 <yingying> ...the slides are on github.
14:02:22 <yingying> ...we focus on hypertext drive apps.
14:03:24 <yingying> ...describes REST apps by URI, media types, link relation types, form relation types, and optionally locations.
14:03:52 <yingying> ...we choose the lighting use case for the PlugREST.
14:04:27 <yingying> ...there is also a draft of this use case on irtf web page.
14:04:53 <yingying> ...the plan of PlugREST is to define basic components like lights and controllers.
14:05:37 <yingying> ...on the long run we hope to interconnect with other app domains.
14:06:32 <yingying> ...imaging you have the TD. We get the TD and can interact with the thing.
14:07:27 <yingying> ...the client communicate with resouce directory. Then we can follow links to get the TD.
14:07:54 <yingying> ...they are actually decentralized.
14:08:24 <yingying> ...the purpose is to find IoT implementation on this.
14:08:59 <yingying> ...what we implemented is a CoRE HAL to support forms and media types.
14:09:19 <yingying> ...we have the hypermedia client.
14:09:48 <yingying> ...we have the Java base and Javascript Runtime.
14:10:01 <yingying> ...this is an example in JSON.
14:10:53 <yingying> Matthias shows an example for hypermedia client.
14:12:08 <yingying> Matthias shows an example of JS in Actinium.
14:12:44 <yingying> Matthias: the plan for Nice F2F meeting is to make the tech demo to find more implementers.
14:12:58 <yingying> ...to discuss how to harmonize W3C and T2TRG approaches.
14:13:20 <yingying> ...sources not ready yet. We will make public this year.
14:13:40 <yingying> rrsagnet, draft minutes
14:14:12 <yingying> Michael: We use different media types. but we don't make application media type.
14:14:19 <yingying> rrsagent, make minutes
14:14:19 <RRSAgent> I have made the request to generate http://www.w3.org/2015/12/09-wot-td-minutes.html yingying
14:14:59 <yingying> ...the easiest way is we go to the media directory, we query some media types we want.
14:16:17 <yingying> Matthias: we can have generic media types that have no semantic info in it. Then you coud group them to have specific media type.
14:17:34 <yingying> ...how to balance them is the key points.
14:17:56 <yingying> Michael: 3rd part is the schema.org.
14:18:06 <yingying> ...there are many different ontologies.
14:18:10 <akeranen> akeranen has joined #wot-td
14:18:19 <akeranen> q?
14:18:28 <yingying> ...this is the work on progress and we should continue.
14:18:45 <akeranen> q+
14:21:03 <yingying> [some discussion on the generic media type and app specific media types]
14:22:11 <yingying> Ari: is there any minimum subset that I could implement before PlugREST.
14:22:35 <yingying> Matthias: yes. I can try to give you the pointer of it.
14:23:11 <yingying> Sebastian: there is already some info on wiki about plugfest.
14:23:23 <yingying> ...All presentations are presented on it.
14:23:52 <yingying> ...please input your name and information and the topic you would like to implement into the table.
14:24:11 <yingying> s/information/organization
14:24:23 <yingying> ...please input by end of next week.
14:24:44 <yingying> ...I would like to take a look at the tech landscape.
14:25:08 <yingying> ...Darko has now transferred the tech landscape from wiki to github already.
14:25:47 <yingying> Darko: We decided to move the landscape to the github.
14:25:56 <yingying> ...everyone can see it and edit it.
14:26:25 <yingying> ...you can see the table containing different consortium and other information.
14:27:07 <yingying> ...We provided some initial structure. Maybe you have better suggestion for the struture. we could discuss it.
14:27:21 <yingying> ...we need more volunteers to work on it.
14:27:49 <yingying> ...if you are now willing to do any part of it, please put your name and we then can move on.
