GBIF users: Been pondering trying to make occurrence downloads easier. One idea has something to do with checking if a download request you make is already in your account. If so, we can just download that and GBIF doesn’t have to waste resources creating it again, and you don’t have to wait as long to get data.

You can install the development version like
# a predicate pred_gte("elevation", 12000L) #> <<gbif download - predicate>> #> > type: greaterThanOrEquals, key: ELEVATION, value(s): 12000
A normal download request would kick off a new download
Using the new function
occ_download_cached() would not be allowed to create a new download request. It has the same user interface as
occ_download(), but instead matches the query predicates against the downloads in your user account, and if it finds a match returns it. Currently it returns the most recent match if there are more than 1, but thinking of just having it return all matches and let the user decide which to use.
occ_download_cached() return the same thing, the download key that you can then pass down to
note: I attempted to wrap the functionality of checking for existing downloads in your account into the existing functions
occ_download_queue(), but the complexity i thought was too much, increasing maintenance pain, more errors, etc.
Any thoughts? Would you use this? If so, anything you’d like changed?
