21:06:14 <kerry> topic: patent call https://www.w3.org/2015/spatial/wiki/Patent_Call
21:06:17 <SimonCox> who is here?
21:06:58 <kerry> topic: SSN/SOSA/O&M: is an observation an event, activity, or information object? see https://lists.w3.org/Archives/Public/public-sdw-wg/2016Aug/0144.html
21:08:45 <roba> kerry - simon has put background on list, some folloups
21:10:20 <roba> simon: refs AGU paper as per link in email - exploring PROV as an upper ontology?
21:10:32 <SimonCox> https://goo.gl/TKlX1l
21:10:32 <kerry> https://goo.gl/TKlX1l
21:12:13 <roba> ... 'punchine on slide 14 "CorePROV– allalignments"
21:15:08 <kerry> q?
21:15:09 <roba> OED: [MASS NOUN] The action or process of closely observing or monitoring something or someone:
21:15:46 <kerry> q?
21:15:47 <ChrisLittle> Q+
21:16:44 <kerry> ack ChrisLittle
21:17:26 <roba> ChrisLittle: where does Event fit - works with Time ontologies
21:18:18 <roba> simon: PROV Activity matches 'occurent'
21:19:24 <roba> q+
21:20:01 <kerry> q?
21:20:07 <kerry> ack roba
21:21:04 <kerry> q+
21:21:35 <roba> roba: who has looked at this and who has issue/ supports?
21:21:52 <roba> kerry: where is om-lite?
21:22:36 <roba> simon: see slides 4,5 - not updated to SOSA work
21:23:11 <roba> ... SOSA had Activity as super-class - people unhappy with subclassing hierarchy
21:24:18 <roba> kerry: use Observing etc?
21:24:40 <roba> simon: want to use a Noun - eg ActivityOf
21:25:35 <SimonCox> https://www.w3.org/2015/spatial/wiki/index.php?title=SOSA_Ontology&oldid=2342
21:27:51 <roba> q+
21:28:47 <roba> ChrisLittle: forecasting under procedure?
21:29:11 <roba> simon: ObservingProcedure -> EstimatingProcedure ?
21:29:23 <kerry> ack roba
21:29:30 <kerry> q?
21:30:34 <roba> roba: what is the entailment regime supported by core (RDFS? if not then SKOS?)
21:31:38 <roba> kerry; RDFS was originally agreed - Krystof backed off - inverseProperties snuck back in.
21:31:50 <kerry> q?
21:32:07 <roba> s/;/:/
21:32:40 <kerry> ack kerry
21:33:14 <roba> simon: as per OED example should choose terms that match natural language as far as possible
21:34:17 <SimonCox> q+
21:34:33 <roba> q+
21:34:59 <DanhLePhuoc> q+
21:35:18 <kerry> q?
21:35:25 <roba> kerry: concerns that SSNX proposal adds extra complexity
21:36:08 <roba> simon: BP work - discussion on HTTP range-14 - is this related  - ssn:observation is an "information object"
21:36:43 <kerry> q?
21:37:59 <roba> ... re rules forn Kerrys paper - support and back up idea of rule - mutiple paths - this is the "art" - make useful paths
21:38:02 <kerry> ack simoncox
21:38:39 <roba> kerry: fill in missing bits using the rules - more reasoning on the back end
21:39:35 <kerry> ack roba
21:41:07 <roba> simon: reflects on O&M
21:41:26 <kerry> q?
21:41:26 <roba> ... terms matched broad community
21:41:35 <SimonCox> q+
21:41:36 <kerry> ack DanhLePhuoc
21:41:59 <roba> roba: modularity and encapusalation preferred way to handle complexity - want modules with specific entailment rules
21:42:54 <roba> DanhLePhuoc: performance is an issue - sensors generate a lot of data - cant afford to force 3-store to do a lot of work
21:43:29 <ChrisLittle> S/encapusalation/encapsulation/
21:43:32 <roba> ...focus somewhere between RDFS and OWL-EL perhaps?
21:43:59 <roba> ... problems database trying to solve now
21:44:28 <roba> ... need to address logic load in parallel with design
21:44:31 <kerry> q?
21:44:48 <kerry> ack SimonCox
21:45:01 <roba> ... commen on Simon's paper - concerned it requires OWL-DL - not well supported from performance
21:45:34 <kerry> q+
21:45:46 <roba> simon: on modularisation - should the core be the supr-classes, the most common use subclasses (hit the 80%)
21:45:51 <roba> q+
21:46:34 <kerry> ack kerry
21:47:01 <roba> kerry: my concern is what goes in core.
21:47:23 <roba> ... what is it supposed to be for
21:48:15 <roba> simon: armin and jano may have different ideas
21:48:31 <kerry> q?
21:48:35 <roba> kerry: core is what IoT , schema.org etc
21:48:44 <roba> ... needs?
21:49:17 <kerry> ack roba
21:49:50 <SimonCox> Apologies for jumping the queue several times. Wanted to catch the discussion, but bad process, sorry
21:50:20 <kerry> q?
21:51:08 <roba> roba: wants core to introduce common terms, superclasses and establish patterns - and support RDFS entailment explicitly.
21:51:11 <DanhLePhuoc> q+
21:51:16 <kerry> ack danh
21:52:25 <roba> DanhLePhuoc: supports explicit entailment regime for core - RDFS - maybe extend to OWL-QL
21:53:13 <kerry> topic: SSN Agenda for Lisbon meeting see https://www.w3.org/2015/spatial/wiki/Meetings:F2F4
21:54:33 <roba> roba: whats the plan here?
21:54:57 <roba> kerry: wanted to air the issues - cant resolve yet - need to bear in mind.
21:54:57 <SimonCox> Two issues on the table:
21:55:05 <SimonCox> 1. Observation - record or activity
21:55:15 <SimonCox> 2. SOSA-Core goals
21:57:13 <SimonCox> Options for SOSA-core: superclasses, vs. most-used classes (for IoT)
21:57:14 <roba> Kerry: moving on F2F at TPAC - describes agenda - proposes trying to put resolutions re core design - contribute via email.
21:57:23 <SimonCox> Implications: entailment regime?
21:57:37 <kerry> q?
21:57:56 <ChrisLittle> Q+
21:59:20 <SimonCox> Which day is the meeting at TPAC?
21:59:36 <roba> q+
21:59:40 <kerry> q?
21:59:51 <kerry> ack ChrisLittle
22:00:56 <kerry> q?
22:01:01 <SimonCox> @Chris 'RecordOfObservation' vs 'ActivityOfObserving'
22:01:03 <kerry> ack roba
22:01:27 <kerry> +1+1
22:01:48 <kerry> q?
22:02:15 <kerry> q/
22:02:40 <kerry> q?
22:03:15 <kerry> q?
22:03:33 <ChrisLittle> +1 to Simon's terminology
22:04:43 <kerry> q?
22:05:06 <roba> kerry: something concrete on modularisation would be worthwhile if possible
