Help with BagIt Setup

[Sherry Lake]

UVa wants to use local storage for BagIt exports but are having trouble with the commands (and setup maybe?). When running this command (using dataverseAdmin's token):

curl -H "X-Dataverse-key: 33020XXXXXXXXXXXXXX7f230e" http://dvdev.lib.virginia.edu:8080/api/admin/submitDataVersionToArchive/:persistentId/?persistentId=doi:10.80100/FK2/PKSBXX/1.1

We get the error message:

{"status":"ERROR","code":404,"message":"API endpoint does not exist on this server. Please check your code for typos, or consult our API guide at http://guides.dataverse.org.","requestUrl":"http://dvdev.lib.virginia.edu:8080/api/v1/admin/submitDataVersionToArchive/:persistentId/?persistentId=doi:10.80100/FK2/PKSBXX/1.1","requestMethod":"GET"}

I am assuming the documentation (API command) is not correct??

Thanks,

Sherry

Sherry,

 

The version has to come before the query param:

e.g.

http://dvdev.lib.virginia.edu:8080/api/admin/submitDataVersionToArchive/:persistentId/1.1?persistentId=doi:10.80100/FK2/PKSBXX

Thanks Jim.

Question if I just wanted the latest version, do I need to put the version in the URL?

Could I just use this in the command: http://dvdev.lib.virginia.edu:8080/api/admin/submitDataVersionToArchive/:persistentId/?persistentId=doi:10.80100/FK2/PKSBXX

Looking at the code, the version number is required. I don’t think it would be hard to either support the :latest-published tag instead of a number or just assume the latest published if the version is not sent, but neither of those is implemented now.

Hi Jim,

Sorry but my sysadmins keep thinking up new questions....

What if a dataset is not published? It doesn't have a version yet, does it?

Can you make bags of unpublished works?

And one more....

Can multiple versions be combined in one bag?

I think the answer is "now" based on the URL needing an exact version #, but I was asked to ask.

In the job description ;-)

 

Bags were originally developed as a way to archive datasets at publication time (with archiving automated as a post-publication workflow), so they can’t currently be created for draft data. If desired, that’s probably a relatively minor change to support in the API.

 

Multiple versions is a more fundamental limit, at least in terms of standards: Bags weren’t designed to handle versions. The newer Oxford Common File Layout specification (https://ocfl.io/0.9/spec/) supports versions and might be a better/additional option for the future. (There are also some folks (e.g. https://stacks.wellcomecollection.org/how-we-store-multiple-versions-of-bagit-bags-e68499815184) who do non-standard things to allow Bags for later versions to refer to files in earlier versions to avoid duplicating the files, which would be a possible interim possibility.).
