Hi Annie,
With additional RAM allocated, the IPT can publish proportionally
larger datasets. However, this can be inefficient (or expensive
in terms of RAM), especially if the dataset has extensions.
To construct the DWCA outside an IPT you will need:
- data files. It's a good idea to check them for common errors
-- incorrect number of columns, duplicate occurrenceIds and so on
(the IPT does several checks like this).
- a meta.xml data description file, linking columns to Darwin
Core terms. This can be written by hand, using various programming
languages, or (often easiest if the process isn't to be repeated)
by using an IPT to make a suitable mapping and extracting the
resulting file.
- an eml.xml metadata file, describing the dataset. The same
applies here -- the IPT is useful for providing a UI to write this
metadata, especially if all 8 are similar.
Once the DWCA exists, it should be copied to a webserver.
Note that using the registry API is not strictly necessary, and a
publisher with a small, unchanging number of datasets outside the
IPT need not use it. They can simply give the helpdesk a URL for
each dataset's DWCA file, and update the DWCA files at those URLs
as necessary.
Using the API is useful for adding additional datasets, making changes (e.g. changing the URL) of the existing 8, or prompting GBIF to reprocess a dataset. To use the API the technical team should create a suitable username (e.g. "usgs" or "bison") on both gbif.org and gbif-uat.org. The latter is our test system. They should then contact helpdesk@gbif.org to ask for permission for that account to make changes under the USGS publisher, or whichever publisher is/are appropriate. This will only be on the test system at first.
It's then possible to register a new dataset under that publisher, following the example here: https://github.com/gbif/registry/tree/master/registry-examples/src/test/scripts and see the result.
For general questions on this, the GBIF API mailing list is probably most appropriate: https://lists.gbif.org/mailman/listinfo/api-users
If you have problems or errors with a specific dataset, helpdesk@gbif.org will be the best contact. (They also read both mailing lists.)
Cheers
Matt
Thank you, Laura, for your replies.
The datasets have been exported from databases and cleaned. They are generally UTF-8 tab delimited files. So it seems that the GBIF Registry API would be the correct solution.
We currently have 8 of these large datasets, only 2 of which would not be updated in the future. Do you have names of GBIF Product Team Members whom my technical team should contact to begin this process? Is there "how to" documentation you can point me to that they should read first?

This email has been received from outside of DOI - Use caution before clicking on links, opening attachments, or responding.
I could also mention that it is possible to script the creation of the Darwin Core Archives and then use the GBIF Registry API for the connections with GBIF. Symbiota, PlutoF and some others are successfully doing this. It does require some initial coordination with our Product Team on how to set up and coordinate the registration process and potentially with our Informatics Team.
Best,
Laura

Subject: [IPT] How does one upload large datasets to GBIF?
Colleagues:
What is the easiest or most popular way to send large datasets to GBIF, ones that are too large for the IPT software (I think that is more than 100MB zipped, 10+million records)? Does one modify their IPT instance? How? Or is there another process that is preferred?
We currently have IPT Version 2.3.6-r3985b6a installed and plan to upgrade to 2.4.0 soon.
A technical answer is what I seek (on behalf of our technical team).
Again my apologies if the answer to my question is easily found and I'm just not finding it.
