Mapping Table

Source Column	Destination RDF Predicate	Comments
`DISTURBANCE_ID`	`rdfs:label`	Encoded in the URIs of the `sosa:Observation` and `ssn-ext:ObservationCollection`. Also used in `rdfs:label` for human readability.
`SITE_ID`	`sosa:hasFeatureOfInterest`	Domain: `ssn-ext:ObservationCollection` Range: `plot:Site`
`TYPE_ID`	`dct:type`	Domain: `ssn-ext:ObservationCollection` Range: a concept in the concept scheme Disturbance Type, matching on the `skos:hiddenLabel` value.
`PROPORTION_ID`	`ssn-ext:hasMember`, `sosa:hasResult`	`sosa:hasResult`: narrower value of Disturbance Proportion Values matched on `skos:hiddenLabel`. `sosa:observedProperty`: Disturbance - Proportion `sosa:usedProcedure`: Based on the value of `TYPE_ID` (Disturbance Type), use a narrower value of Disturbance Assessment Methods.

`COUNT`	`ssn-ext:hasMember`, `sosa:hasResult`	`sosa:hasResult`: Class type: `data:Count` `sosa:observedProperty`: if `TYPE_ID` is 5: then, Stumps Count else if `TYPE_ID` is 6: then, Ringbarked Stem Count `sosa:usedProcedure`: if Stumps Count, then Logging Disturbance Method else if Ringbarked Stem Count, then Ringbarking Disturbance Method
`UPDATE_USER`		Not captured by TERN Plot Ontology.
`LAST_UPDATE`	`dct:modified`	Database entry or last modified time. Encoded with literal as type `xsd:dateTime`.
