***************************************************************


Knowledge graph construction of heterogeneous data has experienced widespread adoption in the last decade from compliance to performance optimizations with respect to execution time. However, emphasis must also be shown to the compliance of knowledge graph construction systems to different use cases and scenarios. This challenge aims at benchmarking knowledge graph systems compliance with numerous different use cases, using declarative mapping languages.


The third edition of the Challenge on KG construction aims to assess the compliance with the new RML specification<https://w3id.org/rml/portal>, tested under classic and newly developed test cases.


Any engine that transforms heterogeneous data into RDF graphs is welcome to submit its results. You can participate with any engine, it is not limited to the main developers of an engine to participate. Thus, we invite anyone who develops engines, changes existing engines, or wants to assess the compliance of an existing engine to participate.  All details regarding the challenge can be found here<https://kg-construct.github.io/workshop/2025/challenge.html>.
