Call for Papers

PADL is a well-established forum for researchers and practitioners to present original work emphasizing novel applications and implementation techniques for all forms of declarative programming, including functional and logic programming, database and constraint programming, and theorem proving.

Topics of interest include, but are not limited to:

Innovative applications of declarative languages
Declarative domain-specific languages and applications
Practical applications of theoretical results
New language developments and their impact on applications
Declarative languages and software engineering
Evaluation of implementation techniques on practical applications
Practical experiences and industrial applications
Novel uses of declarative languages in the classroom
Practical extensions such as constraint-based, probabilistic, and reactive languages

PADL 2023 especially welcomes new ideas and approaches related to applications, design and implementation of declarative languages going beyond the scope of the past PADL symposia, for example, advanced database languages and contract languages, as well as verification and theorem proving methods that rely on declarative languages.

PADL 2023 welcomes three kinds of submission:

Technical papers (max. 15 pages): Technical papers must describe original, previously unpublished research results.

Application papers (max. 8 pages): Application papers are a mechanism to present important practical applications of declarative languages that occur in industry or in areas of research other than Computer Science. Application papers are expected to describe complex and/or real-world applications that rely on an innovative use of declarative languages. Application descriptions, engineering solutions and real-world experiences (both positive and negative) are solicited.

Extended abstracts (max. 3 pages): Describing new ideas, a new perspective on already published work, or work-in-progress that is not yet ready for a full publication. Extended abstracts will be posted on the symposium website but will not be published in the formal proceedings.

All page limits exclude references. Submissions must be written in English and formatted according to the standard Springer LNCS style, see

Page numbers (and, if possible, line numbers) should appear on the manuscript to help the reviewers in writing their report. So, for LaTeX, we recommend that authors use:


As in previous events, it is planned that the conference proceedings of PADL 2023 will be published by Springer-Verlag in the Lecture Notes in Computer Science series.

Work that already appeared in unpublished or informally published workshops proceedings may be submitted but the authors should notify the program chairs about the place in which it has previously appeared.

Papers should be submitted electronically at
Important Dates (tentative)

Abstract submission: October 2, 2022 (AoE) Paper submission: October 9, 2022 (AoE) Notification: November 5, 2022 Symposium: January 16-17, 2023
Distinguished Papers

It is expected that the authors of a small number of distinguished papers will be invited to submit a longer version for journal publication after the symposium. For papers related to logic programming, in the journal Theory and Practice of Logic Programming (TPLP), and for papers related to functional programming, in Journal of Functional Programming (JFP) The extended journal submissions should include roughly 30% more content including, for example, explanations for which there was no space, illuminating examples and proofs, additional definitions and theorems, further experimental results, implementational details and feedback from practical/engineering use, extended discussion of related work and such like.
