ECOOP is Europe’s longest-standing annual Programming Languages conference, bringing together researchers, practitioners, and students to share their ideas and experiences in all topics related to programming languages, software development, systems and applications. ECOOP welcomes high quality research papers relating to these fields in a broad sense.

ECOOP is committed to affordable open access publishing. Recent year’s publications have been published by Dagstuhl’s LIPIcs series under a Creative Commons CC-BY license where the authors retain their copyright. ECOOP articles have been published without open access publishing fee and can be accessed via a DOI. LIPIcs is indexed in DBLP, Google Scholar, Scopus and others.


This ECOOP edition continues the last edition’s innovations, embracing the entire landscape of programming technologies with a revised reviewing and publishing model:

  • Broader Scope. ECOOP welcomes contributions in all aspect of practice and theory of programming languages, systems and environments, ranging the whole spectrum from novel ideas to evaluation of existing solutions. Authors can pick one of four broad categories: research papers, reproduction studies, experience papers, and brave new ideas or pearls. Negative results and short papers are welcome.

  • Continuous Submissions. ECOOP is moving towards frequent submission deadlines. ECOOP 2023 has two rounds of submissions, one in December and the second in March. Each round is double-blind and delivers its results within two months.

  • Collaborative Reviewing. ECOOP encourages constructive reviewing where papers that are not accepted outright are given clear and actionable suggestions for improvements so that they can be resubmitted in subsequent rounds; thus, following the reviewing model of many journals but with timely reviews. Unlike conference reviewing, the same reviewers will remain attached to a submission throughout the process even if it takes multiple rounds.

  • Frictionless Submission. ECOOP enforces neither strict page limits nor strict formatting requirements for submitted papers. Instead, we encourage authors to write what the clearest possible submission while keeping in mind that reviewers can only spend the same finite amount of time on each paper.

  • Artifacts Now. Artifacts supporting the scientific claims of papers can now submitted together with their paper and thus all authors will benefit from the feedback of the artifact evaluation committee.

  • Open Access. ECOOP remains committed to open access, all papers appearing the proceedings of the conference, all talks, and all artifacts will be archived and made available free of charge and without author processing fees.

  • Journal First. ECOOP papers can be submitted to special issues of three journals, TOPLAS, Science of Computer Programming and the Journal of Object Technology. The requirements of these journals apply for submissions. For SCP and JOT, the ECOOP program committee will act as reviewers with the same deadline. TOPLAS follow its own process. JOT is open access.

  • Journal After. Selected papers will be invited to publish extended versions in special issues of our associated journals. An extended abstract of the paper will appear in the ECOOP proceedings. Journal after submission at SCP and JOT are reviewed by the ECOOP PC, while TOPLAS uses its own process.
