Seeking RDF Storage Recommendations for a Marketplace Knowledge Graph

Dear W3C RDF Interest Group,

I hope this message finds you well. I am developing a knowledge graph for an event and product marketplace (e.g., connecting events, venues, tickets, vendors, and user interactions). I aim to use RDF/Linked Data to model complex relationships and enable rich querying.

I am exploring triplestores including Apache Fuseki (OSS), GraphDB Free Edition, and Blazegraph, but seek community perspectives on robust open-source solutions that best implement W3C’s RDF/SPARQL standards for this use case.

Specifically:


  *
Scalability & Performance: For a marketplace with highly connected data (e.g., users ←→ events ←→ tickets ←→ vendors), which tools best handle high-throughput querying and frequent updates?
  *
Inference & Reasoning: Are there solutions you recommend for real-time inferencing (e.g., classifying events based on location/type, validating product relationships)?
  *
Deployment Considerations: Any pitfalls to avoid when managing dynamic data (e.g., changing event dates, inventory) or integrating with existing APIs?

I understand W3C does not endorse specific products, but your collective experience with real-world RDF deployments would be invaluable. Thank you for your time. Even high-level guidance or resources would greatly accelerate our work!

Best regards,

Ugur ACAR
