OCaml Users and Developers Workshop 2023

The OCaml Users and Developers Workshop brings together industrial users of OCaml with academics and hackers who are working on extending the language, type system, and tools. Previous editions have been co-located with ICFP 2012 in Copenhagen, ICFP 2013 in Boston, ICFP 2014 in Gothenburg, ICFP 2015 in Vancouver, ICFP 2016 in Nara, ICFP 2017 in Oxford, ICFP 2018 in St Louis, ICFP 2019 in Berlin, virtually for ICFP 2020 and ICFP 2021, and in Ljubjlana for ICFP 2022.

OCaml 2023 will be again be co-located with ICFP 2023, which will take place in Seattle. We aim to organize it as a hybrid event, so that people can attend and even give talks remotely: talks will be streamed in real-time, and virtual participants will be able to chat and ask questions in writing, but possibly not to speak due to technical difficulties.

August 5th 2023: A temporary list of accepted presentations is available. We are in discussion with the ML workshop to move some of these talks to the ML workshops, so the program may change slightly in the following weeks.

Accepted Presentations

Call for Presentations

Scope

Presentations and discussions focus on the OCaml programming language and its community. We aim to solicit talks on all aspects related to improving the use or development of the language and its programming environment, including, for example (but not limited to):

• compiler developments, new backends, runtime and architectures
• practical type system improvements, such as GADTs, first-class modules, generic programming, or dependent types
• new library or application releases, and their design rationales
• tools and infrastructure services, and their enhancements
• prominent industrial or experimental uses of OCaml, or deployments in unusual situations.

Presentations

The workshop is an informal meeting with no formal proceedings. The presentation material will be available online from the workshop homepage. The presentations may be recorded and made available at a later date.

The main presentation format is a workshop talk, traditionally around 20 minutes in length, plus question time, but we also have a poster session during the workshop – this allows to present more diverse work, and gives time for discussion. The program committee will decide which presentations should be delivered as posters or talks.

Submission

The submission website is available at https://icfp23-ocaml.hotcrp.com/

Please register a description of the talk (typically 2 pages long; it could also be less or more), a clear description of what will be provided by the presentation: the problems that are addressed, the solutions or methods that are proposed. The standard submission format is PDF, typically produced by LaTeX or a markdown converter.

Important dates

• Thursday 1st June (any time zone): Submission deadline
• Thursday 6h July: Author notification
• Saturday 9th September: OCaml Workshop

ML family workshop

The ML family workshop, held on the previous day, deals with general issues of the ML-style programming and type systems, focuses on more research-oriented work that is less specific to a language in particular. There is an overlap between the two workshops, and we have occasionally transferred presentations from one to the other in the past. Authors who feel their submission fits both workshops are encouraged to mention it at submission time and/or contact the Program Chairs.
