# nested and complex queries with multiple predicates
## For more complex queries, it may be advantagous to format the query in JSON format. It must follow the predicate format described in the API documentation (https://www.gbif.org/developer/occurrence#download):
query = { "type": "and",
  "predicates": [
    {  "type": "in",
        "key": "TAXON_KEY",
        "values": ["2387246","2399391","2364604"]},
    {   "type": "isNotNull",
        "parameter": "YEAR"},
    {  "type": "not",
       "predicate": {  "type": "in",
                                "key": "ISSUE",
                                "values": ["RECORDED_DATE_INVALID",
                                                 "TAXON_MATCH_FUZZY",
                                                 "TAXON_MATCH_HIGHERRANK"] }} ]}
occ.download(query)

# The same query can also be applied in the occ.download function (including download format specified):
occ.download(['taxonKey in ["2387246", "2399391","2364604"]', 'year !Null', "issue !in ['RECORDED_DATE_INVALID', 'TAXON_MATCH_FUZZY', 'TAXON_MATCH_HIGHERRANK']"], "DWCA")

occurrences.download_meta(**kwargs)¶

Retrieves the occurrence download metadata by its unique key. Further named arguments passed on to requests.get can be included as additional arguments

Parameters:	key – [str] A key generated from a request, like that from `download`

Usage:

from pygbif import occurrences as occ
occ.download_meta(key = "0003970-140910143529206")
occ.download_meta(key = "0000099-140929101555934")

occurrences.download_list(pwd=None, limit=20, offset=0)¶

Lists the downloads created by a user.

Parameters:	user – [str] A user name, look at env var `GBIF_USER` first pwd – [str] Your password, look at env var `GBIF_PWD` first limit – [int] Number of records to return. Default: `20` offset – [int] Record number to start at. Default: `0`

Usage:

from pygbif import occurrences as occ
occ.download_list(user = "sckott")
occ.download_list(user = "sckott", limit = 5)
occ.download_list(user = "sckott", offset = 21)

occurrences.download_get(path='.', **kwargs)¶

Get a download from GBIF.

Parameters:	key – [str] A key generated from a request, like that from `download` path – [str] Path to write zip file to. Default: `"."`, with a `.zip` appended to the end. kwargs – Further named arguments passed on to `requests.get`

Downloads the zip file to a directory you specify on your machine. The speed of this function is of course proportional to the size of the file to download, and affected by your internet connection speed.

This function only downloads the file. To open and read it, see https://github.com/BelgianBiodiversityPlatform/python-dwca-reader

Usage:

from pygbif import occurrences as occ
x=occ.download_get("0000066-140928181241064")
occ.download_get("0003983-140910143529206")

# turn off logging
import logging
logger = logging.getLogger()
logger.disabled = True
x = occ.download_get("0000066-140928181241064")

# turn back on
logger.disabled = False
x = occ.download_get("0000066-140928181241064")
