6th International Workshop on the Resurgence of Datalog in Academia and Industry

DATALOG 2.0 2026

September 7, 2026

at Klagenfurt, Austria

THE WORKSHOP

Datalog 2.0 is a workshop for Datalog researchers, implementors, and users. Its aim is to bring together researchers and practitioners interested in different aspects of Datalog to share research experiences, promote collaboration and identify directions for joint future research.

The 6th International Workshop on the Resurgence of Datalog in Academia and Industry (Datalog 2.0 2026) will be held in Klagenfurt, Austria, on September 7, 2026. Datalog 2.0 2026 is hosted by the 18th International Conference on Logic Programming and Non-monotonic Reasoning (LPNMR 2026).

The first edition of Datalog 2.0 was held in Oxford, UK, in 2010, and it was by invitation only. Since Datalog has resurrected as a lively topic with applications in many different areas of computer science, as well as industry, the second edition of the workshop, which was held in Vienna, Austria, in 2012, was open for submissions (as also the following editions). The third edition was held in Philadelphia, PA (USA), in 2019. The fourth edition was held in Genova-Nervi, Italy, in 2022. The fifth in Dallas, Texas (USA) in 2024.

PROCEEDINGS

Proceedings shall be submitted to CEUR-WS.org for online publication

SUBMISSIONS

Datalog 2.0 2026 welcomes two types of submissions:

Long papers of up to 12 pages, presenting original research
Short papers of up to 5 pages (excluding references) that may contain either original ongoing research or recently published results

in the following categories:

Technical papers
System descriptions
Application descriptions

The indicated number of pages includes title page and references. For long papers, additional details may be included in an appendix that should be incorporated at submission time (online appendices are not allowed). However, such appendices will be read at the discretion of the program committee.

All submissions will be peer-reviewed. Accepted papers will be submitted for publication in the CEUR Workshop proceedings (http://ceur-ws.org). Authors can opt-out if desired. At least one author of each accepted paper must attend the workshop to present the work. Submissions must be written in English, using the CEURART style (either start with the Overleaf template and select Copy Project in the Menu, or download the offline version and use your favorite editor).

INVITED SPEAKER

Wim Martens

Growing Datalog

Details TBD

Wim Martens is professor for Data Intensive Computing at the University of Bayreuth. He is interested in data management (with a current focus on query language design and graph databases), logic, complexity, and formal language theory. One of his goals is to find a good balance for making programming with data easy, intuitive, precise, and efficient.

VENUE

Klagenfurt, Austria

Klagenfurt, nestled by the stunning Lake Woerthersee in southern Austria, is a vibrant city featuring a unique mix of Renaissance architecture and rich cultural heritage. As the capital of Carinthia, it offers a high quality of life with a delightful culinary scene, ranging from cozy cafes to traditional lakeside eateries.

The city is situated at a historical and geographic crossroads between the Alpine and Mediterranean worlds, which is reflected in its relaxed atmosphere and diverse landmarks, such as the Lindwurm statue and the nearby Minimundus. The University of Klagenfurt (AAU) is a modern, green campus located only a 5-10 minute walk from the shores of Lake Woerthersee and the expansive Europapark, providing an ideal and serene environment for academic exchange. Early September offers pleasant late-summer weather, perfect for enjoying the lake's turquoise waters or exploring the surrounding mountain trails.
