This Week in Neo4j – Neo4j 4.3, SemSpect Graph App, Reconciling Taxonomies, Contest Winners, Relationship Indexes, prov2neo, NODES 2021 Recordings

Neo4j is still abuzz about the recent presentations at NODES 2021, including announcements of Neo4j 4.3, AuraDB Free Tier, and a massive trillion+ relationship graph. This week, Kacha Mukabe, the winner of the Leonhard Euler Idea Contest, is featured for creating an impressive submission using GraphQL despite having no prior Neo4j experience. Neo4j 4.3 has been released with new features such as improved devops support, security improvements, and performance enhancements like smart IO scheduling and finer-grained locking. A Graph App called SemSpect has been released by Thorsten Liebig from Derivo GmbH to explore graphs in a data-driven approach. Liz Michel presented on reconciling taxonomies using ontologies at NODES 2021 and wrote blogs on the topic, while Andreas Schreiber released prov2neo, a Python library for importing PROV documents into Neo4j. The Leonhard Euler Idea Contest winners have been announced, with Developers.Zed, Help Me, and SeedFundMe taking top prizes. Rik Van Bruggen showcased the benefits of relationship indexes in his blog, while Andreas Schreiber's prov2neo enables importing W3C PROV formats into Neo4j. The NODES 2021 recordings are now available, including pre-conference hands-on training sessions and conference sessions.
