Graph Systems and Algorithms

/ Devroom

Call for Participation

The return of the graph. It has been a troublesome year with many ups and downs, but we still want to give researchers, developers, practitioners and whoever else is interested, the opportunity to come together and talk about the latest advancements in the open source graph world. We think that especially now it is important to create a space where people can share their ideas and gain new inspirations

FOSDEM is an annual software developers meeting attended by over 8000+ free and open source enthusiasts from all over the world. Caused by the global pandemic, the FOSDEM 2021 will be the first ever online-only FOSDEM event. The devroom will take place on Saturday, 6th February 2021

In the last year, many organizations added graph analytical capabilities to their systems, e.g. Neo4j, Arango DB and Redis graph, to fulfill the rising demand of analytical use-cases, often to be executed on a steadily growing amount of data.

Graph based data science and machine learning approaches are becoming more and more popular with approaches like graph embeddings and graph neural networks.

Graph query languages became mainstream. GQL, an effort driven by many graph database vendors, will be the first query language since SQL standardized by the ISO. Research groups work on standardizing property graph schemas.

In previous devrooms we saw many great presentations and demos. We hope that we will be able to capture some of the spirit of an onsite event and provide a space for actors and maintainers of graph solutions, researchers, geeks and open source hackers the possibility of presenting their latest work. As always, the devroom will invite both, beginners and experts.


  • Graph Data Science - Graph based feature engineering, Graph Neural Networks, etc.
  • Graph applications - Research, use-cases, industry experience
  • Graph Processing / Analytics Frameworks - Neo4j Graph Algorithms, PGX, etc.
  • Graph database systems - Neo4j, ArangoDB, etc.
  • Graph Streaming and its applications
  • Benchmarks - LDBC Graphalytics, etc.
  • Graph Visualization

This list is not closed, other related topics are always welcome.

How to apply

Important Note The 2021 edition of FOSDEM will be an online-only event. We will therefore prerecord all talks and perform a live Q&A after every presentation. Presenting at FOSDEM implies permission to record your session and distribute the recording afterwards. All videos will be made available under the standard FOSDEM content license (CC-BY).

Talks are submitted via FOSDEM's conference system Pentabarf.
