14:18:59 <glomb> Farshid presents
14:19:44 <glomb> Three proposal: pagination / headers / chunking
14:20:09 <glomb> Chunking: Streaming instead of pagination
14:20:26 <kaz> -> https://pr-preview.s3.amazonaws.com/farshidtz/wot-discovery/pull/145.html#exploration-directory-api-registration-listing Preview - 6.2.2.1.5 Listing
14:20:40 <glomb> mm issue:JSON-LD needs context, Farshid: not necessary
14:21:06 <glomb> HTTP 1.1 chunked transfer encoding

14:22:27 <glomb> Where is it applied?
14:23:27 <glomb> mm - browser support it, variable chunk size
14:24:08 <glomb> mm - almost invisible
14:24:27 <glomb> clients have to request content-lenght

14:25:29 <glomb> Question: how big is the entire message?
14:26:02 <glomb> mm - Content-length optional
14:26:44 <glomb> Farshid: expensive to calculate, can be optimized
14:27:09 <glomb> mm - client can do head
14:28:10 <glomb> Farshid: some concerns that it is not enough, does not prevent pagination
14:29:42 <glomb> glomb - want to have both options
14:29:52 <kaz> -> https://www.w3.org/TR/ldp-paging/#ldpp-ex-paging-303 Linked Data Platform Paging 1.0 - 4.2 Simple paging flow using redirects
14:30:04 <glomb> Both mandatory - both optional?
14:30:31 <glomb> Farshid: Query API should provide pagination
14:31:41 <glomb> mm - Server should optimize
14:32:03 <kaz> s/mm -/mm:/g

14:33:30 <glomb> Chunking for large TDs
14:35:02 <glomb> Payload body - array of TDs
14:35:31 <glomb> glomb - want possibility to add extra info
14:36:47 <glomb> mm - clean up draft, chunking as basic functionality
14:37:38 <glomb> mm - leave pagination for the moment and ask for review
14:38:13 <glomb> Farshid - not compatible

15:09:05 <cris> farshid: please speak about the refactored td
15:09:33 <cris> ben: single things properties, combining listing and filtering
15:10:14 <kaz> i/farshid/scribenick: cris/
15:10:25 <cris> ... spitting in three events
15:10:54 <cris> ... anyother changes?
15:11:24 <cris> farshid: td -> is now things. More readable
15:11:26 <kaz> i/please peak/topic: Issue 133/
15:11:33 <cris> ... is it ok to call them things
15:11:37 <cris> ...?
15:11:37 <kaz> i/please speak/topic: Issue 133/
15:11:49 <cris> mc: I agree with the changes
15:12:02 <kaz> i|please speak|-> https://github.com/w3c/wot-discovery/issues/133 Issue 133 - Refactoring TDD Thing Description|
15:12:56 <cris> ... it is a reasonable change, although it is less readable
15:13:10 <cris> ... is a registration an action?
15:13:19 <cris> farshid: yep
15:14:17 <cris> ... another issue property names in url is not consistent
15:14:30 <cris> s/.../mm:/
15:14:48 <cris> ... should we create a convention for urls?
15:14:58 <cris> ... it is a whole other discussion
15:16:32 <cris> ... urls can change but not the affordance names
15:16:57 <cris> farshid: it is a another issue... it means that the URL can be changed in the spec?
15:17:02 <cris> mm: maybe a TM can help
15:17:46 <cris> farshid: should we call things or tds?
15:17:58 <cris> mm: vote for td
15:18:36 <cris> ... @type : "Thing" is a legacy definition
15:18:43 <cris> ... I am ok eitherway
15:20:37 <cris> ... just stick with things
15:21:28 <cris> ... is sparql a property
15:21:33 <cris> ... is weird
15:23:55 <cris> cris: did we solve the problem of choosing which form to use?
15:24:07 <cris> farshid: sparql is special
15:24:30 <cris> ben: we cannot add sparql as query filter
15:25:03 <cris> ... property vs action is an open question
15:26:35 <cris> andrea: why sparql is not a property?
15:26:49 <cris> ben: we cannot describe it correctly as a form of things
15:27:52 <cris> mm: jsonpath would be much more common
15:27:58 <cris> ... sparql is even optional
15:29:07 <cris> ben: sparql is separate because jsonpath and xpath is more a fragment than a proper high level query lang
15:30:45 <cris> ... also we have still to decide what is really normative
15:31:00 <cris> mm: I would say that once we have a thingmodel we'll use it
15:31:18 <cris> (usually TMs does not have fixed urls)
15:33:00 <cris> mm: closing the meeting, let's keep discuss on the issue
