property

Not captured by TERN Plot Ontology.

Value is a string.

Tina: What station is it on? National Park? Name of the property. X Y Z Station. Would not make as observation because it may occur in other datasets too.

paddock

Not captured by TERN Plot Ontology.

Value is a string.

Tina: Don’t capture. Not useful.

Value is a boolean.

Skip. Duplicate of plot_dimensions.

surface_strew_size

Member of ssn-ext:ObservationCollection with dct:type Site and location

• sosa:observedProperty: Size of Coarse Fragments

• sosa:usedProcedure:

  Status
  colour Blue title done

  Plot Description Method

• sosa:hasResult: A narrower concept of concept Surface Strew Size, matching on the skos:notation.

• TS - I don't think Size of Coarse Fragments is a narrower concept of Surface Strew Size, where does this information come from?

• TS update - Surface Strew Size is the same as Size of (Surface) Coarse Fragments so no need for a narrower concept. Will add alt Label ' surface strew' to obs properties,

Value is an integer or null.

Custodian comment: Value is a foreign key to a look-up table called lut_surface_strew_size.csv. Look-up table was not included in the schema or released with the data. Unit of measure is in millimetres (mm). Look-up table is a classification (codes).

Attached look-up table as CSV:

• sosa:usedProcedure:

  Status
  colour Blue title done

  Plot Description Method

• sosa:hasResult: A concept in the collection Lithology of coarse fragments, matching on the skos:notation.

  • If not found, search for a concept narrower to Outcrop Lithology, matching on the skos:notation.

• TS - not sure if these relationships are correct, need to review

• TS update - Surface Strew Lithology is the same as Lithology of (Surface) Coarse Fragments so no need for a narrower concept. Will add alt Label ' surface strew' to obs properties,

Value is a string and appears to be code, but is not a foreign key to a look-up table.

Custodian comment: Value is a foreign key to a look-up table called lut_lithology. Schema was not correct, so the relationship was not there. Unlike surface_strew_size, the look-up table is part of the data as lut_lithology.
