14:11:17 <dape> ZK: We simplified *older* stuff

14:11:37 <dape> ... can use direct or directory
14:12:04 <dape> MMC: *nothing* gives you back what you have?
14:12:12 <dape> ZK: Is URL needed always?
14:12:22 <dape> MMC: we start from *nothing*
14:12:31 <dape> ... output is set of TDs
14:12:35 <dape> ZK: 2 aspects
14:12:49 <dape> ... developer faces API
14:13:09 <dape> ... delivery mechanism (iterator at the moment)
14:13:24 <dape> ... no pagination
14:13:38 <dape> MMC: implementation can support it internally?
14:13:40 <dape> ZK: yes
14:14:01 <dape> MMC: pagination is more for network
14:15:07 <dape> ZK: stanzas?
14:15:26 <dape> MMC: problematic with Canonicalization which does re-ordering

14:15:51 <dape> FT: w.r.t. ordering
14:16:03 <dape> .. query what is needed first
14:16:16 <dape> ZK: query supported as filters
14:16:33 <dape> ... search meant for filters
14:17:44 <dape> MMC: implementations can do internal filters/searches.. returning full TDs
14:18:20 <dape> MMC: TDs are usually relatively small
14:18:54 <dape> MMC: What about languages? JSON-Path or SPARQL returning parts
14:19:24 <dape> CA: Support just filters TDs but not support selects
14:19:26 <dape> q+
14:21:08 <dape> DP: "selects" for use-cases that purely want to do discovery.. not useful for Consumed/ExposedThing
14:21:24 <dape> ZK: Might use sub-set of queries
14:21:32 <dape> ack dape
14:23:11 <dape> CA: not sure about case whether URL is always needed
14:23:41 <dape> MMC: script says "please discover" ..and comes back with results
14:24:07 <dape> ... open issue... authorize access to TDs
14:24:35 <dape> CA: security parameter needed?
14:25:04 <dape> MMC: existing security mechanisms for TDs .. to fetch
14:25:12 <dape> ... management API?
14:25:51 <dape> CA: not clear: direct/directory is for 2nd phase only
14:26:18 <dape> ... believe we should stick with 2nd phase for now
14:26:30 <dape> MMC: easier for now to use url
14:26:41 <dape> ... in general ... url should not be necessary
14:27:42 <dape> ZK: Yes, need further discussion w.t.r. in Scripting
14:27:58 <dape> ... discussed management API ... with various sub-API
14:29:07 <dape> MMC: technically ... fetching TD might return directory.. should handle gracefully

14:29:58 <dape> ... directories are also "things" ...
14:30:51 <dape> ... maybe it can be figured out automatically what it is
14:31:01 <kaz> q?
14:31:16 <dape> CA: direct returns TD .. even for directory
14:31:38 <dape> .. directory pointing to simple TD should fail with error
14:32:36 <dape> ZK: let's habe internal discussion in scripting next.
14:32:45 <dape> TOPIC: PRs
14:33:23 <dape> SUPTOPIC: Rename DirectoryDescription to ThingDirectory
14:33:27 <dape> -> https://github.com/w3c/wot-discovery/pull/161
14:33:50 <dape> FT: changes @type only
14:33:56 <zkis> present- Zoltan_Kis
14:34:24 <dape> MMC: Looks good to merge
14:34:47 <dape> SUPTOPIC: Rename actions to match properties and events
14:34:51 <dape> -> https://github.com/w3c/wot-discovery/pull/160
14:35:13 <kaz> s/161/161 PR 161/
14:35:16 <dape> FT: Ben asks for using type
14:35:20 <kaz> s/160/160 PR 160/
14:36:10 <dape> MMC: I am ok with type addition but should not be a MUST
14:36:28 <dape> CA: Ben has the opinion that name is not normative
14:36:50 <dape> MMC: "name"s is normative ... anyhow adding @type is okay
14:37:29 <kaz> q+
14:37:40 <dape> ... I am OK with terminology change
14:38:19 <dape> FT: PATCH is gone
14:39:13 <dape> MMC: I disagree with that change...
14:39:45 <dape> ... suggest not to merge it now.
14:39:59 <dape> ... concerns with merging PATCH with PUT
14:42:36 <dape> ... formIndex not easy to specify in scripting
14:42:43 <dape> CA: general problem
14:42:59 <kaz> q?
14:43:26 <dape> DP: formIndex is there but much easier to go with interaction name
14:43:32 <dape> CA/MMC: Yes, much easiere
14:43:53 <dape> s/easiere/easier
14:44:09 <dape> FT: contentType are different for those 2 methods
14:44:47 <dape> MMC: original API seemed simpler
14:45:39 <dape> CA: Maybe work together with TD task force ... w.r.t. selecting methods
14:45:56 <dape> ... e.g., using uriVariables
14:46:54 <dape> MMC: Bens proposal seems to be more RESTful but also puts focus on HTTP
14:47:24 <dape> Kaz: Should clarify our intentions/requirements
14:48:15 <dape> MMC: example/TD should be a ThingModel and normative
14:48:44 <dape> FT: It is an example now but we plan to change it
14:49:28 <dape> Kaz: expected features should be listed normatively in the document
14:49:56 <kaz> s/in the document/in the document in addition to the example code./
14:50:07 <dape> MMC: all directories SHOULD be implementing it
14:50:44 <dape> FT: There is another class we could use ... used in TD for JSON Schema
14:51:09 <kaz> s/Should clarify/agree we should clarify/

14:53:58 <dape> FT: Not sure about the benefits
14:54:02 <dape> .. 3 differents events
14:54:24 <dape> ... I don't mind separating but i don't see the benefit
14:55:11 <dape> MMC: query approach seems more extensible
