json metadata generation

[Danny]

Dear community,

I’ve been trying to get a bit familiar with the R dataverse package and their use of the native api. Within this package they have a function create_dataset() that uses the native api. The intent of the function is to create a dataset in an existing dataverse much like specified at the native api website of dataverse https://guides.dataverse.org/en/latest/api/native-api.html at ‘create a Dataset in a Dataverse’. Both the website and the R dataverse package state that one needs to have metadata supplied in a JSON file format (or at least use the JSON lay-out). The dataverse native api website shows an example of what all current metadata looks like in a JSON format https://guides.dataverse.org/en/latest/_downloads/dataset-create-new-all-default-fields.json. I was wondering if there is anyway one produces such file using a call to a script of some sort. I would imagine it a tiny bit tedious to create such a JSON file from scratch every time one wants to upload a dataset using a script (whether it is curl, R dataverse package, or python pydataverse). This issue is also filed in https://github.com/IQSS/dataverse-client-r/issues/82 , but currently has no resolution. Wondering if other came across this issue and whether people know of a solution.

To work with Dataverse metadata (all types - Dataverses, Datasets and Datafiles), I can recommend using pyDataverse.

https://pydataverse.readthedocs.io/en/latest/user/basic-usage.html#create-dataset

Hint: maybe using the CSV templates are helpful to get the data into pyDataverse.

Thanks. I do know of the pydataverse package, but as an R user I want to be able to use dataverse through R. I can get it working with some fields (author, description, title) to create a metadata scheme and adjust those field at will through my script https://github.com/IQSS/dataverse-client-r/issues/82#issuecomment-795260194. I'd hoped there would be a helper function to create an entire json file from within a script (without the need for an external template) like the case for initiate_sword_dataset.

I'm not sure how much this helps since it's Java instead of R but there's a DatasetBuilder class in dataverse-client-java that lets you construct the necessary JSON to create a dataset comfortably from Java:
