It is my pleasure to invite submissions to the OCaml Users and Developers Workshop 2020, which is again co-located with ICFP and will be held on Friday 28th August 2020 in Jersey City, NJ, USA https://ocaml.org/meetings/ocaml/2020/ Talk proposal submission deadline: May 8th, 2020, AoE (Please redistribute widely.) The OCaml Users and Developers Workshop brings together the OCaml community, including users of OCaml in industry, academia, hobbyists and the free software community. Previous editions have been co-located with ICFP since 2012 in Copenhagen, Boston, Gothenburg, Nara, Oxford, St Louis and last year in Berlin, following OCaml Meetings in Paris in 2010 and 2011. https://icfp20.sigplan.org/home/ocaml-2020 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 ---------- To submit a presentation, please register a description of the talk (about 2 pages long) at https://ocaml2020.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. Important dates --------------- Friday 8th May (any time zone) Abstract submission deadline Friday 26th June Author notification Friday 28th August 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.
