<p>Dear all,</p>
<p>a bit of background from the underlying model that Raul has so
nicely transformed to a more semantic representation - please bear
in mind that Raul's task was not to design a soil ontology, but to
transform the model for the Global Soil Information System GloSIS
towards a semantic representation thereof. For details of that
data model, please go back to the talk that Tomas Reznik and
myself held for this group at the April 7th meeting.<br>
</p>
<p>To point 1 and the definition of bulk density (pretty sure you'll
encounter similar issues in a lot of the concepts for with data is
foreseen) - all the requirements were extracted from the FAO
Guidelines on Soil Description as well as the available drafts
towards GloSIS - thus the semantics of these concepts should be
aligned with those sources, ideally with domain experts, which we
data geeks are definitely NOT (I just understand the structure of
what you do, not the details ;) )</p>
<p>To point 2 representation of the soil domain - while I think the
world is still looking for ONE ontology to support all
requirements, I've become wary of this goal, as ontologies are
strongly guided in their perspective on the world by their use
cases - as GloSIS was designed to collect, harmonize, merge all
available data on soil, it took a measurement-data-centric
perspective, leading to the statement of:<br>
</p>
<p> "So, the domain knowledge is there but is not modelled as
subclasses of soil concepts, but as types of observations of soil
concepts"<br>
</p>
<p>I totally get the requirement for a more user-centric perspective
on soil, but believe this should be a complementary (but
interlinked) ontology representing user concepts and thus suitable
for answering questions such as posed in your example of "is this
soil compact enough, healthy enough or too acidic to support this
type (X) of farming?" - if suitably interlinked, the user-centric
system could then transpose the question of if "farming type X can
be supported" to the measurement-data-centric perspective provided
by GloSIS (accessing information on compactness, healthiness or
acidity), aggregate this measurement data, put it in context, and
return an answer.<br>
</p>
<p>Does this help?</p>
<p>:)</p>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal">Sure, from my side I can say a few
words.</p>
<p class="MsoNormal">Regarding question 1. </p>
<p class="MsoNormal">Indeed, the concepts are not having
a textual description, apart from the codelists:
<a href="https://github.com/rapw3k/glosis/blob/master/glosis_cl_v1.0.0.ttl" target="_blank">https://github.com/rapw3k/glosis/blob/master/glosis_cl_v1.0.0.ttl</a>
</p>
<p class="MsoNormal"><span class="gmail_default" style="font-family:garamond,serif;font-size:large"></span>The
definition is at the owl level, so for example, </p>
<p class="MsoNormal"><span style="color:black">BulkDensityWholeSoil we
can see that</span></p>
<ul style="margin-top:0in" type="disc">
<li style="margin-left:0in"><span style="color:black">is
a subclass of
<u>sosa:Observation</u></span></li>
<li style="margin-left:0in"><span style="color:black">hasFeatureOfInterest
a Layer or a Horizon</span></li>
<li style="margin-left:0in">the <span style="color:black">
observedProperty </span><span style="color:black" lang="PL">is </span><span style="color:black">bulkDensityWholeSoilProperty
</span></li>
<li style="margin-left:0in">and the expected values are
<span style="color:black">numeric (float) measured
in KiloGM-PER-DeciM3</span></li>
</ul>
<p class="MsoNormal">Nevertheless, I agree having also
textual descriptions would be a good addition.
</p>
<p class="MsoNormal">This would require, though, to go
through documentation and excels of the GLOSIS, but
should be done.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Regarding question 2.</p>
<p class="MsoNormal">I think the view on this is a bit
reverse.</p>
<p class="MsoNormal">The main concept taxonomy of the
soil domain is derived from the ISO28258, as you can
see in the picture attached.
</p>
<p class="MsoNormal">Then all the observation types that
we have defined in GloSIS are connected to those soil
concepts (via the
<span style="color:black">hasFeatureOfInterest
property).</span></p>
<p class="MsoNormal"><span style="color:black"><span class="gmail_default" style="font-family:garamond,serif;font-size:large"></span>So,
the domain knowledge is there but is not modelled as
subclasses of soil concepts, but as types of
observations of soil concepts.
</span></p>
<p class="MsoNormal"><span style="color:black">To make
it more explicit, we could make a superclass for all
those observations, e.g., , something like
“SoilObservation” (as a subclass of
sosa:Observation) and then make all our observations
subclasses of that superclass (instead of being
subclass of sosa:Observation). This way it could be
clear that these are observations of soil concepts,
but in terms of explicit semantics is not really
adding much.
</span></p>
<p class="MsoNormal"><span style="color:black">Perhaps
others here have some opinions in this regard?</span></p>

now have ONE zoom room for both meetings and
the easy and convenient calendar generating
links might not auto update. Sorry that this
information keeps changing, please double
check your calendar to make sure it matches

<p class="MsoNormal">We will be meeting next
on 19 May at 2300UTC. If no one comes
forward with a different suggestion, on the
agenda will be pulling together a soil
semantic resource list for the ESIP Summer
meeting (and ourselves!).</p>

presenting please send them my way!</p>
