What is open collaboration?

Open scientific collaboration refers to the forms of collaboration in the course of the scientific process that do not fit under open data and open publications.

It includes different type of outputs such as open code, open hardware, the use of collaborative platforms between scientists and the "citizen-science" phenomenon.

The chosen indicators cover the availability of scientific Application Programming Interfaces (APIs), journals' policies on open code, and number of citizen science projects.

New indicators and updated data will be added over time. 

You can download the chart and its data through the dedicated menu within each chart (top right of the image). 

For more information, see the methodology report.

Availability of scientific APIs

This indicator shows the number of Application Programming Interfaces in the science category of the largest API repository ProgrammableWeb.

Journals' policies with regard to open code

The indicator shows the different policies of journals with regard to open code, based on Stodden, 2013.

Open hardware

This indicator shows the number of open hardware project in the Open Hardware Repository.

Citizens' science projects

This indicator shows the number of citizens science projects in the SciStarter repository and in the Zooniverse repository.

Additional indicators

There are other indicators used to monitor scientific open collaboration, such as:

Case studies

You can here find a set of detailed case studies available for download, that will be updated in the course of the study.


    REANA is a reusable and reproducible research data analysis platform enabling users to re-use and reinterpret preserved data analysis years after the original publication, facilitating reproducibility of scientific results.

  • Recongnising the Importance of Software in Research - Research Software Engineers (RSEs), a UK Example

    An initiative being carried out in the UK (and beyond) to promote and recognise the role of Research Software Engineers (RSEs) in research. RSE is a collective term created to bring together those software experts with an understanding of both research and software engineering.

  • White Rabbit

    An example on how CERN managed to transform the open source software model to capital-intensive innovations, motivating self-interested actors to freely reveal innovations developed with private resources without compensation guarantees.

  • Faculty of 1000

    An open science publishing platform that transform the way science is communicated.

  • The Netherlands’ Plan on Open Science

    Three key ambitions for open science: 100% open access to publications, research data made optimally suitable for reuse, and evaluation and valuation systems to recognize and reward researchers.

  • Polymath Project

    A collaborative website trying to find solutions to unsolved problems in combinatorial mathematics.
