AIMS AND SCOPE
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. Datalog 2.0 is a workshop of 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 experienced a resurgence as a lively topic with applications in many different areas of computer science, as well as industry, the second, third, fourth, and fifth edition of the workshop, which were held in Vienna in 2012, Philadelphia in 2019, Genova in 2022, and Dallas 2024, respectively, were open for submissions.
TOPICS
Authors are invited to submit papers presenting research on the foundational aspects of Datalog, as well as on its applications in other areas of computer science and in industry. Potential areas of application of Datalog may include (among others):
data management, data mining, knowledge representation and reasoning, neurosymbolic applications of datalog, cloud computing, distributed computing, logic programming, privacy and security, probabilistic reasoning, program analysis, programming languages, semantic web, social networks, streaming, verification, web services.
SUBMISSION
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 that may contain either original ongoing research
or recently published results
Submissions of technical papers, system descriptions, and application descriptions, are all welcome. Long papers may additionally contain an appendix in addition to the 12 page limit.
The indicated number of pages includes title page and excludes references. All submissions will be subject to single-blind peer-review. Accepted papers will be submitted for publication in the CEUR Workshop proceedings (http://ceur-ws.org). Authors can opt-out of publication 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 most recent CEURART style (https://ceur-ws.org/HOWTOSUBMIT.html#CEURART).
For paper submission see the Datalog 2.0 2026 CMT site https://cmt3.research.microsoft.com/DATALOG2026/
Up to five best long papers will be invited for a special issue (joint with LPNMR) of the journal of Theory and Practice of Logic Programming (TPLP).
IMPORTANT DATES
Paper registration: June 24
Paper submission: July 1
Notification: July 28
Final versions due: August 15
All deadlines are UTC-12 (anywhere on earth).

Title: Growing Datalog
Abstract:
How do we add features to Datalog to make it a general-purpose programming language?
Doing this in the right way can bring us closer to solving two major challenges: the impedance mismatch in query languages and the challenge of automatic programming posed by Jim Gray.
VENUE
The workshop will be co-located with the 18th International Conference on Logic Programming and Non-monotonic Reasoning (LPNMR) at the University of Klagenfurt.
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.
