64th Online Seminar: OpenAlex

The 64th Helmholtz Open Science Online Seminar took place on Tuesday, April 19, 2022 from 5:00 p. m. to 6:00 p. m. (CEST).

In January 2022, the new open source index OpenAlex – named after the ancient library of Alexandria in Egypt – has launched to replace the Microsoft Academic Graph (MAG), which was discontinued at the end of 2021. The metadatabase offers a free alternative to subscription-based platforms such as Scopus, Dimensions, or Web of Science and contains over 200 million records on scholarly documents, publication venues (journals and repositories), authorship, institutions, and concepts. OpenAlex is developed and maintained by the nonprofit service company OurResearch, based in Vancouver, Canada. It draws its content from the decommissioned MAG records as well as a variety of other sources, including ORCID and Crossref. The catalog is freely accessible via REST API.

The 60-minute event was held in English, conducted via the video conferencing tool Zoom and was not recorded.

Our speaker

On the occasion of the launch, the Open Science Office hosted this online seminar with Dr. Heather Piwowar (ORCID), co-founder of OurResearch.

A longtime advocate for Open Science, Dr. Heather Piwowar is also a leading researcher in research data availability and reuse, including a seminal paper measuring the citation benefit of publicly available research data. She has a bachelor’s and master’s degree from MIT in electrical engineering, 10 years of experience as a software engineer, and a Ph.D. in Biomedical Informatics.




For this event no slides was shared by Heather Piwowar. Instead she presented OpenAlex live during the seminar.


A Factsheet with the key take-aways will be published under CC BY 4.0 International soon.
