OCaml 2015

The OCaml Users and Developers Workshop Vancouver, British Columbia, Canada, September 4, 2015 Colocated with ICFP 2015, the day after the ML Family Workshop.


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 colocated with ICFP 2012 in Copenhagen, ICFP 2013 in Boston, ICFP 2014 in Gothenburg, following the OCaml Meetings that ran until 2011.


The programme is now available.


Discussions will focus on the practical aspects of OCaml programming and the nitty gritty of the tool-chain and upcoming improvements and changes. Thus, we aim to solicit talks on all aspects related to improving the use or development of the language and of its programming environment, including, for example:

  • 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 uses of OCaml, or deployments in unusual situations.


It will be an informal meeting, with an online scribe report of the meeting, but no formal proceedings. Slides of presentations will be available online from the workshop homepage. The presentations will likely be recorded, and made available at a later time.

To submit a talk, please register a description of the talk (about 2 pages long) at EasyChair, providing a clear statement of what will be brought by the talk: the problems that are addressed, the technical 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.

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.
