 Data Explorer	explore	file	A GUI which lists the variables in a tabular data file allowing searching, charting and cross tabulation analysis. See the README.md file at https://github.com/scholarsportal/dataverse-data-explorer-v2 for the instructions on adding Data Explorer to your Dataverse. 
 Whole Tale	explore	dataset	A platform for the creation of reproducible research packages that allows users to launch containerized interactive analysis environments based on popular tools such as Jupyter and RStudio. Using this integration, Dataverse users can launch Jupyter and RStudio environments to analyze published datasets. For more information, see the `Whole Tale User Guide <https://wholetale.readthedocs.io/en/stable/users_guide/integration.html>`_.
 Binder	explore	dataset	Binder allows you to spin up custom computing environments in the cloud (including Jupyter notebooks) with the files from your dataset. `Installation instructions <https://github.com/data-exp-lab/girder_ythub/issues/10>`_ are in the Data Exploration Lab girder_ythub project. See also :ref:`binder`.
-File Previewers	explore	file	A set of tools that display the content of files - including audio, html, `Hypothes.is <https://hypothes.is/>`_ annotations, images, PDF, text, video, tabular data, spreadsheets, GeoJSON, zip, HDF5, NetCDF, and NcML files - allowing them to be viewed without downloading the file. The previewers can be run directly from github.io, so the only required step is using the Dataverse API to register the ones you want to use. Documentation, including how to optionally brand the previewers, and an invitation to contribute through github are in the README.md file. Initial development was led by the Qualitative Data Repository and the spreasdheet previewer was added by the Social Sciences and Humanities Open Cloud (SSHOC) project. https://github.com/gdcc/dataverse-previewers

 A map will be shown as a preview of GeoJSON files when the previewer has been enabled (see :ref:`file-previews`). See also a `video demo <https://www.youtube.com/watch?v=EACJJaV3O1c&t=588s>`_ of the GeoJSON previewer by its author, Kaitlin Newson.

+GeoTIFF
+-------

+A map is also displayed as a preview of GeoTiFF image files, whose previewer must be enabled (see :ref:`file-previews`). Since GeoTIFFs do not have their own mimetype, it is advisable to use this previewer only when GeoTIFFs are used (and not "normal" TIFs). For performance reasons, this previewer has a file size limit of 15 MB and a row/column limit of 50,000 so that larger files are not loaded.

+Shapefile

+Another previewer can be enabled for shapefiles (see :ref:`file-previews`). This previewer only works with zipped shapefiles (see :doc:`/developers/geospatial`). A file size limit of 20 MB is set for this previewer (also because of performance reasons).
