On 8 and 9 October 2020, the second Declarative Amsterdam conference will take place at CWI (Science Park, Amsterdam).

The conference focuses on the technologies and methods used for declarative programming and declarative data. Declarative programming is a style of programming that expresses the logic of a computation without describing its control flow. It allows a software engineer to focus on the 'what' of a program, rather than the 'how'. Declarative programs can be constructed in less time, using much less code than a traditional computer program. Declarative methods for programming and data modelling can help to avoid making the mistakes that have lead to failing software projects for several decades.

Declarative Amsterdam will have presentations on past experiences, current trends and future perspectives in fields such as functional programming, declarative data modelling, databases, XML and related technologies, JSON, CSS, semantic web, data science, data visualization, grammars, parsing, and domain-specific languages.

The first day will feature tutorials, combining presentations and hands-on labs to give an introduction to a specific topic. The second day is a symposium, and consists of shorter presentations. Speakers can discuss new ideas, frameworks, applications of declarative methods, and best practices. We are still optimistic that it will be a real-life event, but we have plan B waiting in the wings as a virtual conference if that turns out to be necessary.

This year, Declarative Amsterdam is being organized by Dutch XML enthusiasts, who share an interest in technologies for data modelling and representation, and declarative methods.

A call for presentations has been published on the website https://declarative.amsterdam/. Tutorials can be between 1.5 and 2.5 hours, and preferably include hands-on labs for participants. Presentations on the second day can be between 20 and 45 minutes. Proposals should at least include a title, duration and summary (90?200 words). Speakers have the option of submitting a full paper or slides, which may be published on the Declarative Amsterdam website. The organizers will select talks that are most interesting to the target audience.

Submission deadline for proposals: June 28, 2020 by midnight CET

Presentations decision will be made before August 15, 2020.

The organizing committee; Bieke van der Korst (Ambrac), Daan Vernooij (Koninklijke Brill NV), Nico Verwer (Rakensi), Pieter Lamers (John Benjamins publishing company), Pieter Masereeuw (Masereeuw ICT - uitgeeftechnologie), Steven Pemberton (CWI).
