Zenodo and General Data Protection Regulation (GDPR)

by Lars Holm Nielsen on May 25, 2018


The General Data Protection Regulation (GDPR) takes effect in Europe on May 25, 2018. The GDPR provides a legal framework for the collection and processing personal information for people in the European Union (EU). The goal is to provide individuals with more control over their personal data.

Zenodo is hosted at CERN, which is an Inter-Governmental Organization (IGO), with its seat in Switzerland. Despite the fact that this means CERN has a special status, we are striving for the same high standards of data protection afforded by GDPR. In fact the GPDR has provisions covering data transfer to/from IGOs and the concept of "adequate protection", i.e. qualified as equivalent. This is what we will offer in Zenodo.

CERN takes seriously the privacy and protection of personal information, and have appointed a Data Protection Officer and, as mentioned above, are working on policies to ensure CERN is compatible with GDPR.

Specifically on Zenodo, we are taking the following actions:

  • Review and update our Privacy Policy to provide specific information about what data we collect, how we use it and when we delete it.
  • Assess our collecting of personal information.
  • Evaluate and ensure that any third-party tools and services are GDPR compatible.

If you wish to review the personally identifiable information about you maintained by Zenodo, or would like your information removed from our records, you may contact us anytime.

New help guide: Advanced search

by Lars Holm Nielsen on April 10, 2018


Visit the new search guide on http://help.zenodo.org/guides/search/.

Users mostly search on Zenodo using only keywords, similarly to how they would search for something on Google or any other other search engine. Keywords are, however, not always enough if you're looking for something specific. Therefore today, we have launched a search help guide, explaining in detail how you can make use of Zenodo's advanced search features.

The guide explains basic concepts of simple field searches, e.g., searching only within the title field, as well as advanced concepts such as range searches, e.g., searching for publications dated between 2010 and 2011. The guide also includes a full reference of all available fields you can search on, so you can construct the exact search query you need.

Under the hood our search engine is powered by Elasticsearch - the most powerful open source search engine available on the market today.



Version field launched!

by Alex Ioannidis on November 2, 2017


As of today, we have extended our metadata schema with the version term, so you can explicitly specify the version of your software, dataset, or any other type of upload. This allows you to use the version tags such as 1.2.1 or 2017.01 instead of the default version numbers such as 1, 2 or 3. The addition is part of our efforts to make software a citable, first-class citizen in the world of scientific research.

Deposit form

At the moment the field accepts any kind of text as input, although we strongly suggest that you use semantic versioning for machine-readability.

The version field is directly integrated within our search results and record pages.

What about GitHub releases?

This change extends to our GitHub integration, which from now on will automatically populate the version field using the git tag of your GitHub release. You don't have to worry about all GitHub releases that have been already published on Zenodo - they have all been updated with their corresponding release tags.

Does this affect the order of the record versions?

No, the order of the record's versions remains as before, i.e.: record versions are ordered chronologically by the record creation time.
