Hi! A rgbif user is asking me about a particular download query, see https://github.com/ropensci/rgbif/issues/245 TLDR: AFAICT this can't work as the API is set up right now. Or am I wrong? That is, he wants to get data for records that match - 10 taxa with their taxonKey value - 3 different basisofrecord values - country = US - hasCoordinate = TRUE - hasGeospatialIssue = FALSE - year range between 1949 and 2011 - month range between 3 and 8 For the taxonKey values, I think he needs to combine those with *OR* operator: "predicate": { "type": "or", "predicates": [ { "type": "equals", "key": "TAXON_KEY", "value": "2475470" }, { "type": "equals", "key": "TAXON_KEY", "value": "2475470" } ] } However, he should combine the other parameters (basisofrecord, hasCoordinate, year, month, etc) using *AND* AFAICT. *BUT*, AFAICT the API only allows one *predicate* key so you can't do what I think is needed here. That is, to say (taxonkey = 1 OR 2 OR 3) + (country = US AND hasCoordinate = true, etc.) I tried sending two *predicate* keys in the API and only the second goes through. Any guidance much appreciated :) The best solution I can think of is to do the query he's doing, but do one for each taxon. Seem like a good solution? Best, Scott
