Add flags for: missing coordinates and missing country

[gbif-portal]

Issue facets: unreported missing values

Records of the datasets from the "RECOLNAT" publisher miss content in important data, like Country, Coordinates, and Collectiondate. The reporting e.g. for https://www.gbif.org/occurrence/search?offset=80&dataset_key=b4b8935c-9ede-43ad-9326-84065b36c927 only included minor taxonomic issues, but none of these rather large ones.

The reason for Collection Date issues missing is possibly that this item is missing from the facet altogether (other dates are there, but not this one) (?)

Collection Date is not something that is in the API I see https://www.gbif.org/developer/occurrence

[MortenHofft]

I don't believe we consider missing coordinates nor missing country an issue anywhere else. Do we?

[ahahn-gbif]

Sorry, I mean: eventDate (occurrence). Or am I overlooking that and it has a different label? Coordinates / country: if they are missing altogether in occurrence data, I think we should at least flag that - after all we are flagging a whole lot of other things, too, that are way less important than location.

[MortenHofft]

Event date is there but not exactly easy to find. it is in the advanced section https://www.gbif.org/occurrence/search?event_date=2017-01-03&advanced=1

and https://www.gbif.org/occurrence/search?month=1&year=1986&advanced=1 is of course also searching event date just with year and month only

[MortenHofft]

missing coordinates. this is essentially what this does https://www.gbif.org/occurrence/search?has_coordinate=false&advanced=1

[MortenHofft]

for unknown country we have https://www.gbif.org/occurrence/search?country=ZZ&advanced=1 but I'm not sure that is properly populated. @MattBlissett will know

[MortenHofft]

But neither of these are considered flags. I agree it is natural to look for them there. It would make sense to add them as far as I can see

[ahahn-gbif]

Speaking for those who would like to point at these reports for highlighting the issues most valuable to fix when contacting a publisher, I would say that including those in the set of flags would make a lot of sense.

[MattBlissett]

Unknown country / ZZ isn't added to records, since it's not necessarily true. There may be a text description, or a country like "USSR" etc.

Negative searches is the overriding feature which would solve a lot of this (where country = null etc).
