DataLad and datalad-dataverse are available for all major operating systems (Linux, MacOS, Windows 10). The relevant requirements are listed below.

An account on a Dataverse site and an API token

An API token can be obtained from the user account settings of web UI of a Dataverse site.


If you don't have DataLad and its underlying tools (git, git-annex) installed yet, please follow the instructions from the datalad handbook.

Dataverse feature support

datalad-dataverse is developed to be compatible with recent Dataverse releases (version 5.13 at the time of this writing). Adding supporting for (incompatible) historic Dataverse releases does not have any priority.

This extension package does not support all Dataverse features. Here is a list of notable unsupported features.

  • This package is focusing on depositing information on the Dataverse datasets in "DRAFT mode", i.e., before they are published for data preservation on Dataverse. Publishing is a dedicated procedure for Dataverse that applies to complete datasets, and is not identical with an upload of one or more files. Updating such published datasets is presently unsupported. It is expected to work, but due to the missing ability to test this feature reliably and automatically, it is not officially supported.

If you are interested in working on adding support for any of them, please get in touch.

Dataverse limitations

Dataverse enforces strict limitations on the names of files and directories in a dataset. In particular for directory labels, it is prohibited to use any non-latin characters, thereby ruling out path names with words in the native alphabets of most languages on this planet (details are on the note below).

DataLad on the other hand, does not impose particular limits on file and directory names. Due to this conflict, this extension package is forced to mangle file and directory names prior deposition on Dataverse. This mangling has no impact on the representation in the DataLad dataset. In particular, it does not impose Dataverse's limitations on other services hosting the same DataLad dataset. It does, however, impact the representation of the dataset rendering in the Dataverse web UI.


Here are some more details on the peculiarities of name mangling.

Dataverse only allows for directory names that have characters from the english alphabet, numbers, and the characters `` , ``-, _, .. There are also restrictions for file names.

That means, Dataverse will not accept names like Änderungen or Déchiffrer, due to the Ä and é in them.

In order to enable the conflict-free representation of any unicode name, forbidden characters are "encoded". In short, every character that is not supported by Dataverse is encoded as -<X><X>-, where the <X> are hexadecimal digits ([0-9A-F]). Depending on the character there might be two or more such digits. This encoding is revertible to ensure reliable conflict-free file access by (mangled) path through this extension package.

In addition, Dataverse "swallows" all `` `` (space), -, and . at the beginning of a directory name. Therefore, we further mangle such names ames by prepending _.

The necessity to mangle, in particular, non-english names is an unavoidable consequence of the character limitations imposed by Dataverse. Mangling enables representation, but at the cost of reduced legibility, an disadvantage, disproportionally impacting datasets of non-english origin.


datalad-dataverse is a Python package available on pypi and installable via pip.

# create and enter a new virtual environment (optional)
$ virtualenv --python=python3 ~/env/dl-dataverse
$ . ~/env/dl-dataverse/bin/activate
# install from PyPi
$ pip install datalad-dataverse

In order to allow additional features for datalad push and datalad clone to be enabled, the datalad.extensions.load config must be set to next and dataverse. Configurations can be set at the dataset level (.datalad/config within the dataset) or any git-config location (local, global, system). To set it globally (meaning it's stored in your ~/.gitconfig) run:

# Make sure datalad-next is loaded whenever a datalad command runs;
# This allows to git push/fetch from/to a dataverse dataset:
$ git config --global --add datalad.extensions.load next
# Same thing for datalad-dataverse, enabling datalad-clone directly
# from the URL of a dataverse dataset landing page.
$ git config --global --add datalad.extensions.load dataverse

Getting started


For detailed instructions, please refer to the Tutorial.

The datalad-dataverse software allows publishing a DataLad dataset to a Dataverse instance. First you have to create an empty Dataverse dataset with a dedicated DOI, which will be used in the code below (see how to do this in the Tutorial).

Next, ensure that your dataset is packaged as a DataLad dataset:

datalad create -d [dataset_location] --force

Then create a dataverse sibling to the DataLad dataset:

datalad add-sibling-dataverse \
  -d [dataset_location] \
  -s dataverse \
  https://demo.dataverse.org doi:10.70122/MYT/ESTDOI

This command will report both the URL of the dataverse instance and its DOI as well as a long URL starting with datalad-annex::. This URL is what will be relevant for cloning the dataset from Dataverse.

Finally, push the DataLad dataset to Dataverse:

datalad push --to dataverse

Once the dataset is available on Dataverse, it can also be cloned using the datalad-annex:: URL provided by add-sibling-dataverse:

datalad clone \

Help others getting started

Its not always obvious to outsiders whether a Dataverse Dataset is a DataLad Dataset as well. To help others get started with your shared datasets, we recommend to add a short DataLad-specific description to your dataset's "Description" metadata. For convenience, a template to copy-and-paste can be found below.

This dataset is a <b>DataLad dataset</b> (https://www.datalad.org), published with
the datalad-dataverse software (https://docs.datalad.org/projects/dataverse).
If you <code>"datalad clone"</code> it, it provides fine-grained data access down to the
level of individual files, and allows for tracking future updates. For this,
DataLad and datalad-dataverse are required. You can find installation instructions
at https://docs.datalad.org/projects/dataverse/settingup.html#installation.
Afterwards, you can clone it with the following command-line call (replace
the two placeholders <code>DATAVERSE-INSTANCE-URL</code> and <code>DATASET-DOI</code>): <br><br>

    <code>datalad clone 'datalad-annex::?type=external&externaltype=dataverse&encryption=none&exporttree=no&url=DATAVERSE-INSTANCE-URL&doi=DATASET-DOI' my-dataset-clone</code> <br><br>

Once a dataset is cloned, it is a light-weight directory on your local
At this point, it contains only small metadata and information on the
identity of the files in the dataset, but not actual *content* of the
(sometimes large) data files.
After cloning a dataset, you can retrieve file contents from available locations
by running <code>"datalad get path/to/directory/or/file"</code>.
This command will trigger a download of the files, directories, or
subdatasets you have specified.<br><br>

More information on DataLad and how to use it can be found in the DataLad
Handbook at https://handbook.datalad.org/index.html. The chapter "DataLad
datasets" can help you to familiarize yourself with the concept of a dataset.

HELP! I'm new to this!
