OCaml Users and Developers Workshop 2014

Gothenburg, Sweden

Call for presentations (past)


Presentations and discussions will 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 (but not limited to) 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.


It will be 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 time.

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://icfp-ocaml17.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. If you wish to perform a demo or require any special setup, we will do our best to accommodate you.

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 and post-proceedings

The ML family workshop, held on the previous day, deals with general issues of the ML-style programming and type systems, and is seen as more research-oriented. Yet there is an overlap with the OCaml workshop, which we are keen to explore, for instance by having a common session. The authors who feel their submission fits both workshops are encouraged to mention it at submission time and/or contact the Program Chairs.

As another form of cooperation, combined post-proceedings of selected papers from the two workshops will be published in the Electronic Proceedings in Theoretical Computer Science series. The Program Committees shall invite interested authors of selected presentations to expand their abstract for inclusion in the proceedings. The submissions would be reviewed according to the standards of the publication.
