Interpretation in TERN Plot Ontology

Encoding each row in RDF requires:

  • An ssn-ext:ObservationCollection with the observation group encoded with dct:type status:todo

Range: sosa:Sample

  • sosa:observedProperty: Soil Sample Depth status:review required Sample doesn’t have observedProperties

  • sosa:hasResult:

    • rdf:type: data:Text

    • data:value: sample_id

  • sosa:isResultOf:

    status:review required Should not be Soil Bulk Density Method? - TS, the sample depths are described in the soil observation method, hence reference to that method.

 

Name has “ID” in it, but the data does not look like an ID. Example values:

  • 20 - 30cm.

  • 0

  • 1

  • 2

  • 0.00 - 0.10

  • 0 - 10cm

  • None

Looks more like a comment on the size of the sample.

status:review required Ideally this should be cleaned and converted to a controlled vocabulary of:

  • 0cm - 10cm

  • 10cm - 20cm

  • 20cm - 30cm

Problem is, since it is entered as free text, in the future, the values could be slightly different and then it will break our pipeline.
