\arguments{
\item{...}{Curl options passed on to \code{\link[httr]{GET}}}

\item{prefix}{(character) A string to specify the metadata format in OAI-PMH
requests issued to the repository. The default (\code{"oai_dc"}) corresponds
to the mandatory OAI unqualified Dublin Core metadata schema.}

\item{from}{(character) string giving datestamp to be used as lower bound
for datestamp-based selective harvesting (i.e., only harvest records with
datestamps in the given range). Dates and times must be encoded using ISO
8601. The trailing Z must be used when including time. OAI-PMH implies
UTC for data/time specifications.}

\item{until}{(character) Datestamp to be used as an upper bound, for
datestamp-based selective harvesting (i.e., only harvest records with
datestamps in the given range).}

\item{set}{(character) A set to be used for selective harvesting (i.e., only
harvest records in the given set).}

\item{token}{(character) a token previously provided by the server to resume
a request where it last left off. 50 is max number of records returned.
We will loop for you internally to get all the records you asked for.}

\item{as}{(character) What to return. One of "df" (for data.frame;
default), "list" (get a list), or "raw" (raw text). For
\code{gbif_oai_get_records}, one of "parsed" or "raw"}

\item{id, ids}{(character) The OAI-PMH identifier for the record. Optional.}
}
\value{
raw text, list or data.frame, depending on requested output via
\code{as} parameter
}
\description{
GBIF registry data via OAI-PMH
}
\details{
These functions only work with GBIF registry data, and do so
via the OAI-PMH protocol
(https://www.openarchives.org/OAI/openarchivesprotocol.html)
