Call for Papers

40th European COnference On Programming (ECOOP 2026)
June 29 - July 3, 2026
Brussels, Belgium
https://2026.ecoop.org/
------------------------------------------------------------------------


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 was 
originally focused on object orientation, but now includes all practical and 
theoretical investigations of programming languages, systems and 
environments. ECOOP solicits innovative solutions to real problems as well as 
evaluations of existing solutions.

ECOOP is committed to affordable open access publishing. Recent years' 
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.

In 2026, ECOOP will be hosted by the Vrije Universiteit Brussel, Belgium, 
between June 29th and July 3rd. More information can be found on the 
conference website: https://2026.ecoop.org

# Submissions

Submissions will be done through HotCRP: https://ecoop26.hotcrp.com. Authors 
are asked to pick one of the following paper categories:

- *Research.* The most traditional category for papers that advance the state 
of the art.
- *Replication.* An empirical evaluation that reconstructs a published 
experiment in a different context in order to validate the results of that 
earlier work.
- *Experience.* Applications of known PL techniques in practice as well as 
tools. Industry papers will be reviewed by practitioners. We welcome negative 
results that may provide inspiration for future research.
- *Pearls/Brave New Ideas.* Articles that either explain a known idea in an 
elegant way or unconventional papers introducing ideas that may take some 
time to substantiate. These papers may be short.

Submission must not have been published, or have major overlap with previous 
work. In case of doubt, contact the PC chairs.

Proceedings will be published in open access by Dagstuhl LIPIcs in the 
Dagstuhl LIPIcs LaTeX-style template. To reduce friction when resubmitting, 
ACM's PACMPL and TOPLAS formatted papers can be submitted as such (with the 
understanding that if accepted, they will need to be reformatted and reduced 
to the page limit).

ECOOP uses double-anonymous reviewing. Authors' identities are only revealed 
if a paper is accepted. Papers must omit author names and institutions, and 
use the third person when referencing the authors' own work. Nothing should 
be done in the name of anonymity that weakens the submission; see the 
Double-Anonymous FAQ on the ECOOP 2026 website. If in doubt, contact the 
chairs.

There is no page limit on submissions, but authors must understand that 
reviewers have a fixed time budget for each paper, so the length of the 
feedback is likely to be unaffected by length. Brevity is a virtue. Authors 
also have to consider that the camera-ready version must be (at most) 25 
pages in LIPIcs format (not including references).

Authors will be given a four-day period to read and respond to the reviews of 
their papers before the program committee meeting. Responses have no length 
limit.

ECOOP will continue to have two deadlines for submissions. Papers submitted 
in each round can be (a) accepted, (b) rejected, or (c) asked for revisions. 
Rejected papers that are submitted to the immediate next round can be 
desk-rejected if they do not sufficiently differ from the previous 
submission. Revisions can be submitted at any later round. Papers retain 
their reviewers during revision.

# Artifact Evaluation and Intent

To support replication of experiments, authors of accepted research papers 
may submit artifacts to the Artifact Evaluation Committee. They will be asked 
whether they intend to submit an artifact at paper submission time. Artifacts 
will be submitted after paper acceptance. It is understood that some papers 
do not have artifacts.

# Journal First and Journal After

We have Journal First/After arrangements with ACM's Transactions on 
Programming Languages and Systems (TOPLAS), Elsevier's Science of Computer 
Programming (SCP) and AITO's Journal of Object Technology (JOT).

Only new research papers are eligible to be Journal First (JF). JF papers 
will have an extended abstract in the ECOOP proceedings. The deadline is the 
same as Round 1 of submissions and the notification is aligned with Round 2 
notification. TOPLAS JF papers should be submitted according to this 
announcement. SCP JF papers should follow this call for papers. JF papers are 
presented at the conference and eligible for awards.

Journal After (JA) papers are papers for which the authors request to be 
considered for post conference journal publication. Once accepted by the 
ECOOP PC, these papers will be forwarded to the journal editors. Reviews and 
reviewers will be forwarded and used at the editor's discretion. JA papers 
will have an extended abstract (up to 12 pages) in the conference proceedings.
