Mapping status

[peterdesmet]

This was already discussed in #12, but since then there are more statuses. For mapped values, see definitions at http://rs.gbif.org/vocabulary/gbif/occurrence_status.xml

• [x] ~A = absent~
• [ ] ~Ex = excluded?~
• [ ] ~Excluded = excluded?~
• [ ] ~I = irregular?~
• [x] ~M = absent Is regular migrant, but decided in #12 to use "absent" rather than "irregular" or "present"~
• [x] ~P = present~
• [ ] ~P?= ?~
• [ ] ~P(I) = ?~

The link to the definitions is dead!

Abbreviations are given in this paper: https://zookeys.pensoft.net/article/28712/

P? = probably present P(I) = Probably only present as an immigrant

I have updated the link above. @dirkmaes33 GBIF uses the values below. I have attempted to map our values as best as possible, but please verify:

class	subclass	includes also	mapping
present		endemic, native, extant	P
present	common	frequent, fairly common
present	rare	uncommon, casual
present	irregular	ephemeral, episodic, vagrant	I, P(I), M
doubtful		possibly extant, probably extant, possibly extinct, presence uncertain	P?
absent		extinct, extirpated	A, Ex
absent	excluded	misidentification, reported in error, erroneous	Excluded

Especially I, P(I), M are a bit tricky to match: but since they all indicate presence due to migration, I would group them under irregular. To be consistent, that means not choosing absent for M @dirkmaes33 agree?

[dirkmaes33]

Absent for M is not correct, they are migrants that occur in a region every summer, just like Vanessa cardui (Distelvlinder) does here ... Migrant is the only correct term and it is strange that GBIF does not have it in the list. Many migrating birds are just like that (only present in summer and elsewhere in winter) and I wonder how they deal with it ... All M's in the list should be treated as migrating birds!

[peterdesmet]

Absent for M was suggested a while ago by you: https://github.com/inbo/eurobutt-checklist/issues/12#issuecomment-444018017. But, let's be defiant and use our own terms then (which will cause some distributions not to be parsed, but at least be correct):

eurobutt	map as	GBIF
P	present	ok
I	irregular	ok
P(I)	irregular	ok
M	migrant	error
P?	doubtful	ok
Ex	absent	ok (we already indicate regionally extinct in threat status)
A	absent	ok
Excluded	excluded	ok

@dirkmaes33 agree with above mapping?

[dirkmaes33]

OK, everything depends on what the definition of "present" is ... If that means present all year long, than many birds will fall in the categorie absent!

[peterdesmet]

Indeed, but I will thus map as above.
