retrieve datasets with API

[Lekan Anifowoshe]

Hello everyone,

I am trying to retrieve all datasets from this url link https://dataverse.harvard.edu/dataverse/Africa. Can anyone tell me how to call these datatsets through API ?

Thank you.

Regards,
Lekan

Hello,

You can call any published/public object through the Dataverse API, given its ID. For Dataverses, the $id may also be an alias (in this case Africa), and this API endpoint in particular will return all objects within a dataverse:

GET http://$SERVER/api/dataverses/$id/contents

However, https://dataverse.harvard.edu/dataverse/Africa returns a 404 for me?

If it helps, here's a script I wrote to download all files in original format from a given dataset.
https://github.com/donsizemore/odum/blob/master/dataverse/download_dataset_original_format.py

Others on the list can certainly give you a smarter answer than I, but that's what I can offer.

The only caveat about using the "contents" API is that it can time out[1] on large lists of datasets. Definitely worth a try, like Don said.

You could try the "List datasets in a dataverse" endpoint of the SWORD API: http://guides.dataverse.org/en/4.7.1/api/sword.html#list-datasets-in-a-dataverse

There's an undocumented “MyData” API you could try: https://github.com/IQSS/dataverse/issues/1299#issuecomment-255547345

Once the "Africa" dataverse has been published, you could try the Search API to list datasets, narrowing down by "subtree": http://guides.dataverse.org/en/4.7.1/api/search.html

I hope this helps,

Phil
