This method provides the ability to update a data or metadata object to the Member Node
provided in the 'x'
parameter. In DataONE, both the original object and the new object are
maintained, each with its own persistent identifier, and the 'obsoletes' field in the SystemMetadata is
used to reflect the fact that the new object replaces the old. Both objects remain accessible.
updateObject(x, ...)# S4 method for MNode
updateObject(x, pid, file = as.character(NA), newpid, sysmeta, dataobj = NULL)
The MNode instance on which the object will be created
(Not yet used.)
The identifier of the object to be updated
the absolute file location of the object to be uploaded
The identifier of the new object to be created
a SystemMetadata instance describing properties of the object
a raw
object to use for the upload, instead of the contents of the file
argument.
A character
containing the identifier if successful.
In the version 2.0 library and higher, this operation can utilize an
'dataone_token' option to provide credentials for write operations in DataONE.
The authentication token is obtained from DataONE (see your profile on https://search.dataone.org).
See the vignette("dataone-overview")
for details.
Alternatively, the version 1.0 approach of using an X.509 certificate in a default location of the file
system can also be used. This certificate provides authentication credentials from
CILogon https://cilogon.org/?skin=DataONE. See vignette("dataone-overview")
for details.
