Known Issues With LinkedEarth Representation of the PAGES2k Dataset
This page lists the issue identified with the representation of the PAGES2k dataset in LinkedEarth.
Ghost measured variables
Because the LinkedEarth Ontology requires the representation of the archive type to be made on a measured variable, it was decided to create "ghost" measured variable if only the inferred variables were archived. The following datastes have improperly set the inferred variable to a measured variable with a Property:ProxyObservationType (L) set to "Ghostmeasured".
Instead, these datasets should have an additional entry in the JSON-LD file with the proper Property:ProxyObservationType (L).
Earliest Sample Date/Latest Sample Date
The period covered by the record should be provided at the variable level through the HasMinValue and HasMaxValue properties.
Pages showing EarliestSampleDate can be found here while pages showing LatestSampleDate can be found here.
