ECOOP is a programming languages conference. Its primary focus has been object-orientation, though it is liberal in its taste and, in recent years, has accepted quality papers over a much broader range of programming language and programming topics. Its sweet spot tends to be the theory, design, implementation, optimization, and analysis of programming languages that enable or enforce abstractions -- data, control, security, performance -- across various programming styles, from object-orientation to reactivity to spreadsheets. It encourages both innovative and creative solutions to real problems, and evaluations of existing solutions in ways that shed new insights. Following recent precedent, it also encourages the submission of reproduction studies.

The 30th edition of the ECOOP conferences series will take place from 18-22 July, 2016 in Rome, Italy. Conference site: http://2016.ecoop.org/

# Call for Papers

ECOOP 2016 solicits high quality submissions describing original and unpublished results. The program committee will evaluate the technical contribution of each submission as well as its general relevance and accessibility to the ECOOP audience according the following criteria:

# Topic

ECOOP has become a broad conference for high-level programming language ideas, while retaining expertise in object-oriented topics. The past editions give a clear indication of the kind of material appropriate and interesting to the conference. Please consult the program chair if you have questions about fit and appropriateness.

# Originality

Papers must present new ideas and place them appropriately within the context established by previous research in the field. The paper must clearly identify what this contribution has accomplished and how it relates to previous work.

# Significance

The results in the paper must have the potential to add to the state of the art or practice in important or significant ways. The paper must challenge or change informed opinion about what is possible, true, or likely.

# Evidence

The paper must present evidence supporting its claims. Examples of evidence include formalizations and proofs, implemented systems, experimental results, statistical analyses, and case studies.

# Clarity

The paper must present its claims and results clearly. It must be organized so that it is easily understood by an audience with varied expertise.

# Length

Papers must be no longer than 25 pages, including references, figures and integral appendices. See below for information about additional appendices. However, papers should be as long as necessary, but not longer. Reviewers will expect papers to be at least 18 pages long, beyond which authors will not be penalized for papers that are shorter than the page limit.

# For Reproduction Studies: Empirical Evaluation

Common in other sciences, reproduction means independently reconstructing an experiment in a different context (e.g. virtual machine, platform, class of applications) in order to validate or refute important results of earlier work. A good reproduction study will include thorough empirical evaluation, meeting high statistical standards. It will contain a detailed comparison with the previous results, seeking reasons for possible disagreements.

# Publication Imprint

ECOOP Proceedings are published by Dagstuhl LIPIcs. LIPIcs is only the publisher; authors retain ownership of their content.

# Paper Submission

Only papers that have not been published and are not under review for publication elsewhere can be submitted. Double submissions will be rejected without review. If major parts of an ECOOP submission have appeared elsewhere in any form, authors are required to notify the ECOOP program chair and to explain the overlap and relationship. Authors are also required to inform the program chair about closely related work submitted to another conference while the ECOOP submission is under review.

Submissions will be carried out electronically via HotCRP:

https://ecoop2016.hotcrp.com/ (the site will be alive in the next few weeks)

Papers must be written in English.

# Anonymity

ECOOP will use light double-blind reviewing whereby authors’ identities are withheld until the reviewer submits their review (as usual, reviews are always anonymous). To facilitate this, submitted papers must adhere to two rules:
- author names and institutions must be omitted, and
- references to authors’ own other work should be in the third person (e.g., not “We build on our previous work …” but rather “We build on the work of …”).

However, nothing should be done in the name of anonymity that weakens the submission or makes the job of reviewing the paper more difficult (e.g., important background references should not be omitted or anonymized). A document answering frequently asked questions that hopefully addresses many common concerns is available here. When in doubt, contact the program chair.

# Additional Material

Clearly marked additional appendices, not intended for the final publication, containing supporting proofs, analyses, statistics, etc, may be included beyond the 25 page limit. There is also an option on the paper submission page to submit supplementary material, e.g., a technical report including proofs, or the software used to implement a system that cannot easily be anonymized. This material will be made available to reviewers after the initial reviews have been completed when author names are revealed.

Reviewers are under no obligation to examine the supplemental material. Therefore, the paper must be a stand-alone document, with the supplemental material viewed only as a way of providing useful information that cannot fit in the page limit, rather than as a means to extend the page limit. In our experience, reviewers are more likely to consult additional appendices rather than separate technical reports.

Authors of papers that have been submitted but not accepted by previous prestigious conferences may additionally submit a Note to Reviewers. The Note to Reviewers should a) identify the previous venue(s) (e.g. POPL 2016, OOPSLA 2015); b) list the major issues identified by the reviews at those venues; and c) describe the changes made to the paper in response to those reviews. These notes will be made available to reviewers after the initial review has been completed and author names have been revealed.

# Response period

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 formal length limit, but concision will be highly appreciated and is likely to be more effective.

# Artifact Evaluation

To reward the creation of artifacts and support replication of experiments, authors of accepted research papers can submit artifacts (such as tools, data, models, or videos) to be evaluated by an Artifact Evaluation Committee. Artifacts that pass muster will be recognized formally, and the Artifact Evaluation Committee will give an award for the most distinguished artifact.
