Roadmap

ERA Ontology / “ERA Vocabulary” means a Technical Document issued by the Agency pursuant to Article 4(8) of Directive (EU) 2016/797, establishing human and machine readable data definitions and presentations and linked quality and accuracy requirements for each data element (ontology) of the rail system.

The Agency shall ensure the ERA vocabulary is maintained to reflect regulatory and technical developments affecting the rail system.’

Graph-based Live Anomaly Detection on Semantic Streams

ARSINOE SustainGraph (Knowledge Graph)

A lightweight RDF parser which streams triples directly from/to disk or standard input/output.

Materials and sample queries for the Practical Data Consumption Workshop at Rail Data Forum 2025.

Hypothesis Discovery on RDF Knowledge Graphs

Scientific knowledge representation, knowledge that originated from well designed experiments and sound statistical analysis. The dynamics of knowledge and the different levels of reliability are intended to be modeled.

A super fast Graph Database uses GraphBLAS under the hood for its sparse adjacency matrix graph representation. Our goal is to provide the best Knowledge Graph for LLM (KG-RAG).
