Re: Comment on the SOSA ontology

Dear all

Thanks to the work of Stephan Bernard
we have created a first example of our weather archive using SOSA ontology.
I attached some drawing that describe our usage of sosa.

Has you may notice we reused directly the skos vocabulary that describe 
weather property
NERC Vocabulary Server version 2.0 (NVS2.0).
We also reuse the QUDT vocabulary.

You will notice that we do not follow your weather example 25
based on sample.
The thing is that we find usefull the creation of the sample based on 
the weather station location e.g.

<Air?lat=45.75&long=4.85>

But this sample will be the sample of several Feature of Interest: wind, 
precipitation, atmosphere etc...
Thus we should create

<Wind?lat=45.75&long=4.85>, <Precipitation?lat=45.75&long=4.85>,<Atmosphere?lat=45.75&long=4.85>

We prefere to reuse some existing vocabulary like the sweet ontology 
that propose wind, precipitation and atmosphere URI.
Moreover we should recreate the observed property based on the sample URI.

<Air?lat=45.75&long=4.85#temperature> Would become
<Precipitation?lat=45.75&long=4.85#rainfall_amount>
<Atmosphere?lat=45.75&long=4.85#temperature>

  

We obviously could create it automatically but we do not see the utility 
of the creation of these new instances.

We do not describe anyThing about FoI and Sample, because we expect that 
the skos vocabulary NERC is sufficient to express the FoI.
If you thing that our hypothesis are false we could modify it.

We reuse also the inXSDDateTime Property which is now deprecated. We 
will replace it by the new property in inXSDDateTime.

I give you the link to the snorql interface if you want to play with our 
weather archive
http://ontology.irstea.fr/weather2017/snorql/.
We already now that we have a problem with time filter. We are looking 
to solve this issue.
