The Scholars Portal Dataverse team is happy to announce that the Dataverse File Previewers tool has been installed and enabled for Scholars Portal Dataverse users.
This new tool will allow users to view certain file types, like images and audio/video files, directly in their web browser without needing to download the file. Files that are restricted will not be able to be previewed unless the user has permissions to download the file in the system.
File previews can be open by clicking on the "Explore" button in the list of files in a dataset, or by clicking "Explore" on a file landing page.
After clicking "Explore", a new tab will open in your browser to preview the file. Depending on the file type, you may see an image, text, or a playable audio/video file.
The following file types can be previewed in Scholars Portal Dataverse:
- Text and document files: txt, html, pdf
- Audio files: mp3, mpeg, wav, ogg
- Image files: gif, jpeg, png
- Video files: mp4, ogg, quicktime
- Statistical formats: Stata, R
- Hypothesis annotations
The Scholars Portal Dataverse team is pleased to announce the completion of the development project “Dataverse for the Canadian Research Community,” funded by CANARIE’s program for Research Data Management software tools.
The 18-month project involved innovative development of the Dataverse platform to better support Canadian researchers around data deposit and sharing with national and international collaborations. The development work addressed key themes around data curation, authentication, scalability, and large-file support (described below).
The Data Curation Tool (DCT) allows users to create and edit variable-level metadata for tabular files (e.g., SPSS, R, Excel, CSV), as a modular application launched from within Dataverse. The aims of the DCT are to improve data curation workflows within Dataverse, to improve the ability for data reuse, and to support the application of standards and best practices using the Data Documentation Initiative (DDI) metadata standard.
Other features include the ability to view summary statistics and charts about the data. User edits are saved back to Dataverse and can be exported outside the platform.
Special thanks to the University of Ottawa for the French translations.
- The DCT was launched in Scholars Portal Dataverse on October 31, 2019.
- Code openly available in GitHub
- Hosted webinar (see recording)
- Published blog post on features and functionality
Scholars Portal configured Dataverse to work with Shibboleth for institutional single sign-on through the Canadian Access Federation (CAF), an identity management service for Canadian research institutions run by CANARIE. Dataverse requires each user’s email, first name, last name, and affiliation, which are released under Research and Scholarship (R&S) entity profile.
The benefits of using the CAF's R&S include ease of collaboration between Dataverse as the service provider and institutions as the identity providers. CAF’s vetting process ensures secure and trustworthy exchange of identity information.
For Dataverse users, this integration results in a simpler log-in process with one less username and password to manage.
- Launched in Scholars Portal Dataverse on October 31, 2019
- 14 institutions now participating
- Planning upcoming webinar with Portage and CANARIE on the benefits of joining CAF's R&S profile
- Documentation in Scholars Portal Dataverse Guide coming soon
Scholars Portal connected Dataverse to cloud storage by hosting files in a test cluster of the Ontario Library Research Cloud (OLRC).
The aim is to optimize system architecture for scalable use and to leverage an existing, distributed Canadian data storage network.
- Developed in test environment with an innovative design
- Plan to upgrade to cloud storage for Scholars Portal Dataverse (end of 2020)
Scholars Portal developed proof-of-concept integration with Globus as a large-file transfer mechanism. Dataverse users would run Globus Connect Personal (free software) and have a Globus account to upload/download files to/from Dataverse.
Our testing demonstrated robust transfers up to 100 GB in size and up to 38,000 files. We are continuing to collaborate and consult with the Harvard's IQSS Dataverse team to bring this proof-of-concept development work into the core code.
- Developed in test environment
- Code available in GitHub
- Plan to launch in Scholars Portal Dataverse (early 2021)
- Blog post with demo of Globus deposit coming soon

The Scholars Portal Dataverse team has been hard at work on the new Dataverse Data Curation Tool as part of our Canarie RDM grant project. Development on this project is being led by Victoria Lubitch, Programmer/Analyst at Scholars Portal.
The Data Curation Tool (DCT) allows data owners and curators to create and edit variable-level metadata for any tabular file in a dataset. Users can access this tool as a modular application once they’ve uploaded a tabular file (e.g., SPSS, R, Excel, CSV) to a dataset in Dataverse.
The Data Curation Tool
Similar to tools like SPSS, the DCT allows users to view summary statistics about their data, add variable information like 'Interviewer Instructions' or 'Notes', create variable groups, and indicate weighting variables.

Once edits have been completed and saved back to Dataverse, these changes can then be downloaded as an XML file or exported to a codebook.
Example of a codebook in Dataverse
Usability testing sessions were recently completed with 5 participants, who worked through a series of tasks and helped us identify areas where the user experience could be improved in the tool. We’re now working on translating this tool to be used in French, with translations provided by the University of Ottawa.
A demo of this tool is available online, and the code can be accessed on GitHub. The Data Curation Tool will be launched with the next Scholars Portal Dataverse upgrade, currently scheduled for the end of October, and will be available for community testing soon.

Welcome to our Scholars Portal Dataverse blog, where we will be sharing news and updates about the Dataverse platform and service, including development work. Our first blog post provides an update about the development project "Dataverse for the Canadian Research Community"! This project is funded by CANARIE's RDM grant program and led by Scholars Portal and University of Toronto Libraries, with support from CARL and Portage.
We're currently about half way through our 18 months of development work (October 2018-March 2020).
The aim of the grant is to enhance Dataverse to address the needs of a broad range of researchers in Canada through improved scalability, improved integrations with Canadian cloud storage and authentication providers, and better support for data curation workflows. These three areas of development are described further below and will be discussed in more detail in future blog posts.
The goals of the first leg of the project include:
The goals of the second leg of the project include:
The goals of the third leg of the project include:
Our Project Timeline & Deliverables roadmap is included below. We have completed our first two deliverables and are currently working on the third.
For our first deliverable to connect Dataverse with Swift as the primary storage service, we stood up a test instance of Dataverse connected to the OLRC. The SP team tested upload and download functionality, as well as the integrity of files stored, with a variety of file types and sizes, along with other functionalities core to Dataverse. The idea behind this type of configuration would allow us to more easily scale the system, add storage resources, and run the platform more optimally.
We have also successfully configured Dataverse to work with Shibboleth for single sign-on using the University of Toronto as the test case. We are now initiating a pilot project with interested institutions to test out new sign-up and login workflows. More details to come in another blog post.
Currently, we are working on completing our third deliverable - developing the Data Curation Tool. We presented the DCT prototype at NADDI (link to slides) and at the Dataverse Community Meeting (link to slides). Feel free to test out the Data Curation Tool - Prototype and stay tuned for a future blog post describing the development of this tool.
In the fall, we will start to focus on the large-file support and storage connection pieces of the project.
We will be sharing more details about these deliverables and details about the development work in upcoming blog posts!
