22:56:11 <trackbot> Meeting: Web of Things Interest Group Teleconference
22:56:11 <trackbot> Date: 07 July 2015
22:56:31 <Soumya> RRSAgent, make logs public
22:56:58 <Soumya> present+ Arne, Soumya
23:02:44 <Soumya> present+ Scott
23:08:53 <Soumya> Scott: Physical web discussion
23:09:06 <Soumya> Scott: web page to control
23:09:27 <Soumya> Scott: started 18 months ago and open source project
23:09:31 <joerg> joerg has joined #wot-di
23:09:50 <Soumya> Scott: discovered privacy and efficieny issues
23:09:57 <Soumya> Scott: use BLE
23:10:48 <Soumya> Scott: BLE is connection less, advertise based
23:11:12 <Soumya> Scott: stick to single basic packet, 18 bytes
23:11:58 <Soumya> Scott: step 1 advertise
23:12:21 <Soumya> Scott: step 2 - client, open sourcing of client
23:13:04 <Soumya> Scott: going through proxy is good for content, privacy
23:13:39 <Soumya> Scott: considering spam and security
23:14:16 <Soumya> Scott: physical web should reflect original spirit of web, so no centralized authority
23:14:57 <Soumya> Scott: safe search API, get rid of phising sites, spams from beacons
23:15:42 <Soumya> Scott: https://github.com/google/physical-web/blob/master/documentation/introduction.md
23:16:07 <Soumya> Scott: standardize the broadcasting
23:17:22 <Soumya> Arne: question - easy to clone such beacon, is there a mechanism to prevent that
23:18:11 <Soumya> Arne: depending on context
23:18:33 <Soumya> Scott: lots of security issues, discussion on parking meter use case
23:19:14 <Soumya> Scott: being interactive is the key
23:19:54 <Soumya> Scott: Arne's concern is a valid one, need to consider spam filtering, trying to make it more secure
23:21:34 <Soumya> Arne: Apple's iBeacon is centralized approach
23:21:47 <Soumya> Arne: what are pros and cons?
23:22:06 <Soumya> Scott: there is no register, just a number for iBeacon
23:22:24 <Soumya> Scott: difficult to figure out what to do with the number
23:22:45 <Soumya> Scott: need to have apps, difficult for discovery
23:23:06 <Soumya> Scott: iBeacon is centralized which is against the philosophy of web
23:23:44 <Soumya> Scott: users need to give a lot of permissions
23:24:29 <Soumya> Scott: user might receive a lot of notifications from such beacons
23:25:14 <Soumya> Joerg: physical web could be entry point for WoT
23:25:45 <Soumya> Joerg: is there a different means of interaction
23:26:23 <Soumya> Joerg: having a browser find and click on things is the simplest
23:27:17 <Soumya> discussion on that
23:27:55 <Soumya> Scott: devices could be broadcasting URLs, schema based ad saying a device is a light
23:28:06 <Soumya> Scott: self discovery
23:28:29 <Soumya> Scott: a lot of emphasis on security
23:28:46 <Soumya> Scott: trying to form a proximity-dns
23:28:59 <Soumya> Scott: not going too far in protocol stack
23:31:36 <Soumya> Scott: mDNS version is there
23:31:45 <Soumya> Scott:  it solves some security issues
23:31:57 <Soumya> Scott: not everything is good with BLE
23:33:02 <Soumya> Scott: use multiple tech like SSDP, mDNS, BLE
23:34:27 <Soumya> next Arne's discussion
23:35:24 <Soumya> Arne: structure the thoughts of discussion in wot-di
23:35:38 <Soumya> Arne: extend the wiki page with new tech on discovery
23:35:52 <Soumya> Arne: landscape divided into four categories
23:36:03 <Soumya> Arne: discuss the categorization aspect
23:36:24 <Soumya> Arne: next aim - derive generic discovery interaction patterns
23:36:27 <Soumya> Arne: for WoT
23:36:36 <Soumya> Arne: one could be finding things around me
23:36:50 <Soumya> Arne: first category - UriBeacon
23:38:33 <Soumya> Scott: comment - finding things - "white-listed" things from pre-installed apps (iBeacon) and "unknown" or "any" things (uribeacon)
23:38:53 <Soumya> Arne: wiki modified
23:39:02 <Soumya> Arne: finding thing in my network
23:39:31 <Soumya> Arne: mDNS
23:39:51 <Soumya> Arne: implemented by Apple Bonjour, UriBeacon
23:40:06 <Soumya> Arne: next SSDP, multitask approach
23:40:14 <Soumya> Arne: CoAP based approach
23:40:39 <Soumya> Arne: next web service discovery
23:40:52 <Soumya> https://www.w3.org/WoT/IG/wiki/Discovery_Categories_and_Tech_Landscape
23:41:22 <Soumya> Arne: third category - searching in directory
23:42:03 <Soumya> Arne: first candidate is CoRE resource directory
23:42:38 <Soumya> Arne: second - XMPP IoT discovery
23:43:05 <Soumya> Arne: third - sparql endpoints, a complex one, allows advanced queries
23:43:23 <Soumya> Arne: fourth categories - accessing thing metadata
23:43:38 <Soumya> Arne: access metadata resources after we find things
23:44:03 <Soumya> Arne: CoRE link format is a candidate, provides a well known entry point
23:44:36 <Soumya> Arne: HATEOAS is another one
23:45:48 <Soumya> Scott: comment - JSON-LD could be used in place of XML
23:46:08 <Soumya> Arne: we are looking at JSON-LD in thing description
23:46:33 <Soumya> Scott: suggest to include JSON-LD in category four
23:47:38 <Soumya> Joerg: hook to what is discussed in TF-TD, hand over from discovery from thing description
23:48:48 <Soumya> Soumya: joint TF-DI and TF-TD call at 9AM and proposed discussion there
23:49:33 <Soumya> Joerg: not defined  what is web thing in tech landscape wiki
23:52:41 <Soumya> Joerg: looking for bringing web connectivity at small things
23:53:03 <Soumya> discussion on coming F2F in bay area
23:53:25 <Soumya> Joerg: start a principle kind of taxonomy of categories
23:54:10 <Soumya> Joerg: short taxonomy to compare technologies for discovery
23:54:33 <Soumya> Joerg: put them at the beginning of the wiki sections
23:54:49 <Soumya> Arne: tie that up with use cases, list also pros and cons
23:55:23 <Soumya> Scott: add - things that want to be discovered, things that want to be controlled, put a bit in the physical web
23:56:26 <Soumya> Scott: category 1 and 2 are finding real things while category 3 is finding resources, directories
23:56:49 <Soumya> Scott: category 3 might need UI based search
23:57:17 <Soumya> Arne: agrees on the points
23:57:40 <Soumya> Scott: we can put a LDAP server in category 3
23:58:43 <Soumya> RRSagent, generate minutes
23:58:43 <RRSAgent> I have made the request to generate http://www.w3.org/2015/07/07-wot-di-minutes.html Soumya
23:59:37 <Soumya> present+ Joerg
00:01:36 <Soumya> Joerg: XMPP IoT discovery - built for things that are largely distributed - look for a thing with particular metadata or location or serial no. - not sure about what is look up in directory
00:03:14 <Soumya> Scott: discussion on interoperability and metadata, structure of things, discovery, metadata - need to know what is the stack to be created
00:04:12 <Soumya> Joerg: certain scenarios do not have directories while some others might need to register themselves into directories
00:04:57 <Soumya> Joerg: diff kinds of discovery, how they are addressed in tech landscape, commonalities in technologies, context and purpose of discovery
00:05:56 <Soumya> Scott: interface between the categories using "an address"
00:06:24 <Soumya> Joerg: good comment
00:08:33 <Soumya> Soumya: continue the discussion on next TF-DI meeting
00:08:42 <Soumya> RRSAgent, draft minutes
