30 August 2022 Migration and update of Read & Publish licences

Papago has been migrated to a more modern and powerful server. ACM, AIP and IOP have been added to the Read & Publish licenses recognised by Papago.

15 mars 2023 Adjustment of the tree structure The Papago tree structure has been completely revised to integrate the new SNSF OA provisions and the Horizon Europe programme (Plan S). The former SNSF branch for projects that started before April 2018 has been removed


The adapted concept, logic tree and original answer sheets in French were developed by Micaela Crespo from the Department of Research and International Relations of the University of Lausanne. The source code for this tool was developed by Thomas Henkel of the Cantonal and University Library of Friboug. It can be reused, modified, built upon and improved freely, but we ask that the authorship of the code be attributed to the Papago project. The code is available to all on our GitHub page.

If you have any questions or comments about Papago, you can write to us at In addition, if you encounter an error or malfunction, do not hesitate to report it to us.


This project was strongly inspired by the tool on the Rights and Obligations of Researchers to Distribute their Publications in Open Access developed by the University of Lille, Willo.

We would like to thank Romain Féret of the Digital Library Department at the University of Lille for his collaboration, advice and support in the design of this tool.

This tool was developed as a collaboration between the Université de Lausanne and the Université de Fribourg. We wholehartedly thank our colleagues from the Swiss National Open Access Work Group and the Research Consultants at the University of Lausanne for their feedback during beta testing. We also thank Andrea Hacker (University of Bern) and Silvio Blindella (USI) for the English and Italian translations, respectively.


In view of the multilingual situation in Switzerland, as well as this project, and the conversational nature of the personal assistant, we have named the Papago tool, a word in Esperanto meaning "parrot".  

Papago is an online questionnaire that provides respondents with customized scenarios.

Papago is composed of 2 complementary parts:

  • A form that provides customized scenarios based on the answers to the questions with a final summary of the respondent's situation.
  • Personalised sheets in PDF format, accessible by a link at the end of the form, which make it possible to detail the guarantor's situation and his or her rights, obligations and financing opportunities. These files are hosted on the servers of the University of Lausanne.

Papago also uses SHERPA/RoMEO (, an online resource that aggregates and analyses publisher open access policies from around the world and provides summaries of self-archiving permissions and conditions of rights given to authors on a journal-by-journal basis, to further personalise the answer sheets depending on the Journal and its required embargo period.

Papago seeks to bring together in one place all the essential information on the rights and obligations of researchers with regard to the open access distribution of their publications. Based on the answers provided by the respondents, it makes it possible to build a personalized scenario, adapted to the researcher's situation.

The flowchart

The flowchart can be broken down into 2 phases (these two phases are transparent to the respondent):

  • Phase 1 focuses on the source of funding and includes at least 2 questions regardless of the answer to the first question. The sponsor must indicate whether its publication has been publicly funded. If so, it must indicate the origin of this funding. If the respondent's publication is the result of an H2020 research project, he or she must indicate whether the project began before or after January 1, 2017. If his publication is not the result of a project that has been specifically funded, he must indicate whether at least half of his salary comes from public funds.
  • Phase 2 is about publication: the respondent must indicate whether the publication is distributed under a Creative Commons license or on a paid basis. If the respondent's publication is from an H2020 research project, he or she must indicate whether the publication is already being distributed from an open archive. This makes it possible to know if they must take additional steps to meet their obligations.
