create higher level obsv prop - ASLS

[meganrwong]

Added for soil profile chapter, with members -

DEPTH

TYPE

ABUNDANCE Has some hierarchy within. Voids-macropores-abundance-course and –fine – I put under voids-macropores-abundance

SIZE - this went at top level as is not re geographical or linear extent necessarily

DISTINCTNESS

STRENGTH – already created - Checked has all 5 members (2 parents, 3 child)

LITHOLOGY – already created - Checked has all members

SHAPE

GRADE

QUALIFICATION

QUESTION - from soil profile chapter ASLS

STRUCTURE

added - Structure-articifial-aggregates, Pans-structure , Material-structure

The following instances seemed to have two high level properties -

sprop:structure-pedality-grade - skos:narrower : GRADE, STRUCTURE

sprop:structure-pedality-size - skos:narrower : SIZE, STRUCTURE

sprop:structure-pedality-type - skos:narrower : TYPE, STRUCTURE

grade, size and type are not exclusive to structure

Is there a better way of doing these @dr-shorthair ?

[meganrwong]

just for the record, think this is ok -

GRADE – There is field-soil-texture-mineral 'grade' was not in the URI but it was in the prefLabel:Mineral soils field texture grade.

So, I to ‘grade’

field-soil-texture-organic is not a grade - so not added under 'grad

[meganrwong]

'qualification' has been added as Obsv Prop

Member - ‘field-texture-qualification'

@dr-shorthair not sure if 'Qualification' is an obsv prop

It may have a relationship to GRADE and its member field-texture-grade that may need to be expressed, but I’m not sure that is in scope of what we are doing here atm (may be skos:related of ‘field-texture-qualification' and ‘field-texture-grade')

[meganrwong]

CONSISTENCE – Not created as high level obsv prop - reasonable not to @dr-shorthair

I’m not sure consistence should be split out – perhaps the following just go under ‘strength’ ‘type’ and ‘degree’

sprop:consistence-strength

sprop:consistence-plasticity-type

sprop:consistence-plasticity-degree

[meganrwong]

@dr-shorthair for record here is what has not been added as Observable Properties from ASLS soil profile chapter as there was only one instance. Could be added later as/if required. Let me know if you want any added now.

Have not add these higher level obsv prop – they have only 1 instance under

PERMEABILITY

DRAINAGE

MAGNETIC-ATTRIBUTES

EFFERVESCENCE of carbonates in fine earth

CEMENTATION

CONTINUITY

NATURE

FORM

CONDITION

FABRIC

DIAMETER - would go under linear extent

CONTRAST

?COLOUR – does not make sense to create given contexts is it found in (3 instances all with different use of colour)

Mottle-colour, colour-value and colour-stat

?DISTRIBUTION – only 1 instance

Course-fragment-distribution

(FIELD – not obsv prop) - does not make sense to add as upper level P161 – Field texture

[meganrwong]

@dr-shorthair Are we missing Obsv Prop members - under 'Fabric' - earthy, sandy rough and smooth? p181

[meganrwong]

@dr-shorthair here are some additional notes when pulling higher level obsv prop from soil profile chapter. Apologies putting them all here, just so they don't get lost for now -

Is horizon name prefix and horizon name suffix an obsv prop? They are not in Obsv Prop collection

Are we only putting coded in? are transitional horizons, bleached horizons and cracking clays features

I can’t tell where subdivisions of horizons, lithological discontinuities and buried soils fit in SOSA model. They are more instructive re how to assign horizon classifiers?

sprop:depth def: Give depth to the entity at the site of soil observation, in metres, either above or below the soil surface, excluding litter and living vegetation - source of defs?

What obsv prop would colours be recorded against that are not recorded as hue, value chroma (e.g. ‘brown’ ‘yellowish brown’ ‘brown yellow’)

Texture

Sprop:texture – should this be field texture? (outside of this there are lab-texture and texture)

(just noting there are lots of rules throughout not yet encoded – eg ‘if a soil is organic it must be qualified thus….’ P167)

Can we accom field textures outside of YB classifiers, or when method is not known (do they all follow northcote – how can we tell particularly if they provide results outside of the YB classifiers?)

Structure

Are we missing sprop:structure-compound-pedality? Or is this a feature? P 180

Where do clods and fragments go – are they features? Or obsv prop? P 181

Fabric

What are earthy, sandy, rough and smooth? Classifiers?

Voids

Creation of higher level obsv property is not always required/appropaite here is an example -

(VOIDS>CRACKS)

sprop:voids-cracks

Voids and cracks also read as a feature type, hopefully people won’t misuse.....

In order to keep the issue-threads together, it is best to create a new issue for each question. I've copied your questions into new issues, as listed above, except for the last comment https://github.com/ANZSoilData/def-au-domain/issues/2#issuecomment-1208912454

[meganrwong]

@dr-shorthair so everything in upper case here we'd add these as observable properties even though they have only 1 member in Yellow book?

PERMEABILITY

DRAINAGE

MAGNETIC-ATTRIBUTES

EFFERVESCENCE (of carbonates in fine earth)

CEMENTATION

CONTINUITY

NATURE

FORM

CONDITION

FABRIC

DIAMETER - would go under linear extent

CONTRAST

DISTRIBUTION

[meganrwong]

has all been broken out to separate issues

[dr-shorthair]

Yes I think so
