20:16:13 [krp]
Holger: sent email; Luis not on call

20:18:50 [krp]
Topic: alignment of MMI device and platform ontologies and SSN
20:19:08 [krp]
Holger: MMI are aware of the alignment issues; work is in progress
20:20:55 [krp]
Holger: how are deployments being handled? Attached to platform or instrument?
20:21:35 [krp]
... how are sub-deployments being handled in relation to a new deployment?
20:22:06 [krp]
Which wiki page is this, Holger?
20:22:19 [Holger]
http://www.w3.org/2005/Incubator/ssn/wiki/Deployments,_Systems_and_Devices
20:25:45 [krzysztof_j]
ack, in this case it is a process
20:26:20 [krp]
Holger: is deployment a state... a lifetime of a system
20:26:57 [krp]
krp: Is deployment an event.. a process that happens to the installation
20:26:59 [krzysztof_j]
yes, i would think so
20:28:10 [krzysztof_j]
entity:sensor participatesIn process:deployment
20:28:46 [krp]
Can you re-deploy the same system instance?
20:28:50 [krzysztof_j]
ack
20:29:49 [krp]
Holger: the deployment is putting the sensors in the field, not the time the sensor is in the field
20:30:11 [krp]
krzysztof_j: and the configuration of the sensors for that environment
20:31:05 [krp]
Holger: three options: the act of putting the system in the field
20:31:14 [krp]
... the time the system is in the field
20:31:36 [krp]
... the configuration of the system for that environment
20:33:35 [krp]
indeed - does it matter
20:33:39 [krp]
?
20:36:25 [krp]
kelsey: we need to remember that many sensor are not static. Data from them moves in space and time.
20:40:55 [krp]
In the wider framework of: http://www.w3.org/2005/Incubator/ssn/wiki/Key_Sensor_Concepts

20:41:42 [krp]
Holger: would it make sense to have an act of deployment, which is a process? Construction and deconstruction
20:42:34 [Zakim]
+[IPcaller]
20:42:56 [michael]
zakim, IPcaller is me
20:42:56 [Zakim]
+michael; got it
20:43:44 [kelsey]
installed = commissioned and uninstalled = decomissioned?
20:43:55 [krp]
yes, that's clear terminology
20:45:22 [krp]
Arthur: should be some way to represent that the sensor is deployed in one place, and then another
20:50:32 [michael]
I can - but you'll have to catch me up on the bits I just missed
20:50:44 [krp]
What is the intention of the diagram on the wiki from MMI?
20:50:55 [krp]
in relation to whether it's the event of deployment
20:51:12 [krp]
or is it trying to solve being able to resolve when and where an observation was made
20:51:13 [krp]
?
20:51:49 [krp]
Right.. so what we care about is where the *measurement* was made..
20:51:56 [krp]
... but we're talking about devices and systems
20:53:43 [michael]
+q
20:54:40 [krp]
Holger: we next need to look at time
20:54:49 [Holger]
ack michael
20:55:04 [krp]
michael: dolce has the idea of moving through space and time... so is a location fixed in both time and space?
20:55:51 [krp]
krzysztof_j: entities participating over the lifetime
20:56:17 [krzysztof_j]
locations are participants in the lifetime/deployment of the sensor
20:57:16 [krp]
how is a lifetime scoped? would a given system have more than one? (lifetime ~=deployment?)
20:57:34 [kelsey]
yes
20:57:39 [krzysztof_j]
+1
20:58:50 [krp]
so lifetime/deployment is scoped as between commissioning and decommissioning?
20:59:04 [krzysztof_j]
ok
20:59:30 [krzysztof_j]
yes
21:01:21 [krp]
arthur and holger: lifetime is perhaps misleading, but can define deployment in terms of (de)commissioning
21:02:00 [krp]
kelsey: what is the relationship between the system lifetime and that of the constituent devices
21:03:14 [krp]
do we have to decide if we can model both cases?
21:04:21 [michael]
agreed, those are options our model should allow
21:04:35 [krp]
right, to whatever granularity is appropriate
21:05:05 [michael]
+q
21:05:29 [krp]
Yes, many thanks!
21:05:47 [krzysztof_j]
YES, thanks holger!
21:05:49 [kelsey]
Thank you Holger and best wishes in your new pursuits!
21:05:57 [krp]
