<krzysztof_j> hi

<krzysztof_j> iam

<Holger> ScribeNick: krp

email to Luis re: MMI ontology

Holger: sent email; Luis not on call

<Holger> http://www.w3.org/2005/Incubator/ssn/wiki/File:OperatingModel.png

Holger: not heard from Payam on operation/survival model
... has anyone heard anything from Payam regarding the operating model?

<Holger> http://www.w3.org/2005/Incubator/ssn/wiki/Deployments,_Systems_and_Devices

alignment of MMI device and platform ontologies and SSN

Holger: MMI are aware of the alignment issues; work is in progress
... how are deployments being handled? Attached to platform or instrument?
... how are sub-deployments being handled in relation to a new deployment?

Which wiki page is this, Holger?

<Holger> http://www.w3.org/2005/Incubator/ssn/wiki/Deployments,_Systems_and_Devices

<krzysztof_j> ack, in this case it is a process

Holger: is deployment a state... a lifetime of a system

krp: Is deployment an event.. a process that happens to the installation

<krzysztof_j> yes, i would think so

<krzysztof_j> entity:sensor participatesIn process:deployment

Can you re-deploy the same system instance?

<krzysztof_j> ack

Holger: the deployment is putting the sensors in the field, not the time the sensor is in the field

krzysztof_j: and the configuration of the sensors for that environment

Holger: three options: the act of putting the system in the field
... the time the system is in the field
... the configuration of the system for that environment

indeed - does it matter

?

kelsey: we need to remember that many sensor are not static. Data from them moves in space and time.

In the wider framework of: http://www.w3.org/2005/Incubator/ssn/wiki/Key_Sensor_Concepts

Holger: would it make sense to have an act of deployment, which is a process? Construction and deconstruction

<kelsey> installed = commissioned and uninstalled = decomissioned?

yes, that's clear terminology

Arthur: should be some way to represent that the sensor is deployed in one place, and then another

<michael> I can - but you'll have to catch me up on the bits I just missed

What is the intention of the diagram on the wiki from MMI?

in relation to whether it's the event of deployment

or is it trying to solve being able to resolve when and where an observation was made

?

Right.. so what we care about is where the *measurement* was made..

scribe: but we're talking about devices and systems

<michael> +q

Holger: we next need to look at time

michael: dolce has the idea of moving through space and time... so is a location fixed in both time and space?

krzysztof_j: entities participating over the lifetime

<krzysztof_j> locations are participants in the lifetime/deployment of the sensor

how is a lifetime scoped? would a given system have more than one? (lifetime ~=deployment?)

<kelsey> yes

<krzysztof_j> +1

so lifetime/deployment is scoped as between commissioning and decommissioning?

<krzysztof_j> ok

<krzysztof_j> yes

arthur and holger: lifetime is perhaps misleading, but can define deployment in terms of (de)commissioning

kelsey: what is the relationship between the system lifetime and that of the constituent devices

do we have to decide if we can model both cases?

<michael> agreed, those are options our model should allow

right, to whatever granularity is appropriate

<michael> +q

Yes, many thanks!

<krzysztof_j> YES, thanks holger!

<kelsey> Thank you Holger and best wishes in your new pursuits!

michael: thanks to Holger for his work chairing the group

<krzysztof_j> bye bye
