OCaml Users and Developers Workshop 2022

It is my pleasure to invite submissions to the OCaml Users and Developers Workshop 2022, which will be held on Friday, 16 September 2022 in Ljubljana. As usual, it will be co-located with ICFP, but this year, it will be again held in person!

Important dates

  • Wednesday 1st June (any time zone): Abstract submission deadline
  • Friday 15th July: Author notification
  • Friday 16th September: OCaml Workshop


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.


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.


To submit a presentation, please register a description of the talk (about 2 pages long) at https://ocaml2022.hotcrp.com/ providing a clear statement of what will be provided by the presentation: the problems that are addressed, the solutions or methods that are proposed.

LaTeX-produced PDFs are a common and welcome submission format. For accessibility purposes, we ask PDF submitters to also provide the sources of their submission in a textual format, such as .tex sources. Reviewers may read either the submitted PDF or the text version.

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.

Looking forward to them!

Just saw this reminder. Although I am late to see this, I will try to submit my work as soon as possible.


To offer additional opportunities to contribute to the OCaml workshop, and to align with the ML family workshop, to which you are also cordially invited, the submission deadline has been extended by a week to Friday, June 10 (anywhere on Earth).
