NMT Skeen library has chosen Zenodo, developed and managed by CERN, as a data repository. Zenodo is an online repository that accepts research products in many forms—articles, datasets, images, posters, software, and much more! Deposit into Zenodo is free and open: There are no file format restrictions, and files up to 50GB can be uploaded (though Zenodo will accept larger files on a case-by-case basis).
- Your data will be assigned a DOI. This will mean that whatever you upload will have a unique identifier and will be more easily citable.
- You can control how accessible you want your dataset to be. Zenodo includes options to allow you to select access rights, access conditions, and licenses for your uploads
- Your data will be preserved! As previously mentioned, CERN developed and manages Zenodo. Your data will live on CERN servers in the CERN Data Center.
- What format is your data in? Is there an accepted standard in your research community? If possible, select an open format, like CSV, XML, or JSON
- What type of data are you uploading? Is the data you’re uploading raw data, or has it been manipulated for, or modified due to, analysis? If you would like your data to be reused, you may want to consider uploading raw data rather than any modified data to the greatest extent possible. On the other hand, if you are archiving data associated with a particular publication, you may want to archive and/or share your derived data.
- What does your data look like? If you’re uploading tabular data, it should be structured in a way that makes sense. Column headers should be your data’s variables, and each row should contain an individual observation.
- What about your metadata? Metadata is helpful to include—though in a separate file. A separate metadata file can allow you to include comments, to include information about your data’s units, to specify how you’ve treated null values, etc.
- You may have a number of different files to include in your dataset—perhaps you have several data files, a metadata file, and a readme file. Zenodo will allow you to upload multiple files, packaging them together might make them easier to retrieve.
Now that you have a file/files to upload, navigate to www.zenodo.org. Select the “Login” or “Sign up” option at the top of the page. You should be brought to a login screen. Zenodo offers options to either sign in by signing up for a new account or to use a login from Github or ORCID.
Once you’ve logged in or created an account and then logged in, select the “Upload” tab at the top of the page. You’ll be brought to an upload landing page. From here, select “New Upload.”
The upload process is straightforward. The key is to include as much valid metadata with your upload as possible. Doing so increases the findability and usability of your dataset.
Start the upload process by selecting (or dragging and dropping) the file(s) you plan to upload. After selecting the files, you’ll have to press the “Start upload” button at the top-right of the box.
File upload type
The next section asks you to select the format of your upload, select what best describes your upload.
The next section asks you to fill in basic information about your upload. Here, you’ll fill in:
- The publication date you’d like associated with your dataset. The date you begin the upload process is the default.
- The title of your dataset.
- The author(s), along with affiliation information, of the dataset.
- A description of the dataset.
- Some keywords associated with your dataset. We recommend using appropriate terms from the Unified Astronomy Thesaurus (UAT) later in the “Subject” section, but if there are any terms you’d like to use that aren’t in the UAT, you should use them here in the “Keywords” field.
The following section requires you to select access rights and a license for your dataset. The options you select will depend on what you’d like to allow others to be able to do with your data. If you would like to allow others to access and/or use your work without seeking your permission, we recommended selecting Open Access and an appropriate license. Selecting Open Access also gives your upload higher visibility on Zenodo.
- Open Access: By selecting this option, your dataset will be fully available according to the terms of the Creative Commons license you select. For more information about the available Creative Commons licenses and what they mean, please visit https://creativecommons.org/licenses/
- Embargoed Access: This option is similar to Open Access, but allows you to select a future date on which your upload will be published. Select the date and the license if you’d like this option.
- Restricted Access: Select this option if you plan to allow others to access and/or use your work on a case-by-case basis. Someone who would like access to your dataset will have to contact you for permission. Please note that it is against Zenodo’s terms to charge other users for access to your uploads.
- Closed Access: Select this option if you would like to prevent others from accessing your upload. Only the metadata you include with your upload will be visible to others. This option may be appropriate if you would like to use Zenodo to archive or preserve your dataset but not necessarily to share it with anyone else.
Zenodo includes an option to allow you to request to have your upload included in a specific “community,” which function essentially as collections. Type NMT into the box to list our communities. Once you publish your upload, the community’s owner will be notified of your request to have your dataset added.
Related or alternate identifiers
Use this section to link your upload to other related works. For example, if you’ve published an article related to the dataset you’re uploading, you may want to include that work’s DOI and/or ADS bibcode and to select the appropriate relationship from the dropdown menu. You’re not limited just to assigned identifiers, though; you can also include URLs or URNs and their relationship to your upload.
This section allows you to identify all other individuals who contributed to your dataset (beyond the authors you identified in the “Basic information” section). These are individuals who perhaps don’t have primary intellectual responsibility for the dataset you’re uploading, but still played in a role in its creation. If applicable, select an appropriate role from the dropdown for each contributor.
References, Journal, Conference, Book/Report/Chapter, & Thesis
These sections are unlikely to apply to a dataset you upload. Instead, if your dataset is related to another published work like an article, thesis, conference proceeding, etc., you should include that work’s identifier(s) in the “Related/alternate identifiers” section with the appropriate relationship.
Add any appropriate terms from a taxonomy or controlled vocabulary, like the Unified Astronomy Thesaurus (UAT). Include both the term from the UAT (in the “Term” box) and the URL for the term (in the “Identifier” box). As mentioned previously, include any terms you’re not able to find in the UAT in the “Keywords” field in the “Basic information” section.
Save and Publish
Now that you’ve completed the record, you’re ready to publish your dataset! Double check to make sure you’ve completed all of the steps, and then select the “Save” button (either at the top or bottom of the page). Once your upload has been saved, you’ll be able to select “Publish” to complete the process.
Please contact library staff at firstname.lastname@example.org if you have any questions or need any assistance with this process.
