Notes This bdq:Supplementary test is not regarded as CORE (cf. bdq:CORE) because of one or more of the reasons: not being widely applicable; not informative; likely to return a high percentage of either bdq:COMPLIANT or bdq:NOT_COMPLIANT results (cf bdq:Response.result). A Supplementary test may be implemented as CORE when a suitable use case exists.

Needs to consider other terms, at least the depth terms, to determine if verbatim depth should contain a value. Most terrestrial data will correctly not contain a value in dwc:verbatimDepth as there is no depth to that location. Data without a verbatimDepth is fit for almost all uses.

chicoreus commented 9 months ago

We probably want to collect the verbatim notempty tests into a single UseCase, not simply put them out as supplementary. Substantial more thought is needed on what the data quality needs are that would make us data is unfit for use when verbatim data are not present.

Tasilee commented 9 months ago

This test is similar to #247, #249, #251, #252 and as I commented on #247, all these should be Supplementary (and Closed) for now as they are "not informative" as they stand, and I would not like us to be further distracted. There could well be use cases, and we have commented adequately to inform future use.
