Stardog Union is the company blog at stardog.com, writing about data and programming. Since 2012, 15 different Hacker News readers have linked it 34 times, most often “Stardog 4: Polyglot Graph Database”. It is still writing: the last post was on 2026-10-28, and you can follow it by feed.
Too few sampled comments (13) to say how often HN recommends it.?
Why HN links it
HN readers mostly link stardog.com as a knowledge graph and triplestore product, usually pointing to its SPARQL tutorial or docs. The comments praise the product, not any writing on the site.
Summarised by Claude from a sample of 13 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Stardog makes your AI intelligent with a knowledge graph-powered semantic layer that unifies enterprise data and activates your existing stack for better AI.

What Hacker News says?
The data is stored as a bunch of triples but it encodes a graph. You can use tools like sparql to query that graph. https://www.stardog.com/tutorials/sparql/

HN discussionYou might want to reach out to Al Baker or Kendall Clark at Stardog. Their product is more RDF centric than for generic graphs like Neo4j, but is in my opinion a much better product. They have a community version, and have open sourced several pieces, but it is commercial. https://www.stardog.com/docs/ If you want pure Open Source then Titan might be a good fit for Gitter. http://titan.thinkaurelius.com/

HN discussionStardog[0], a semantic/ontological[1] database, is probably best in class, and is closed source. Anyone interested in writing a open source triplestore, email me ;) [0] http://stardog.com/ [1] They've started calling it a graph database, though I think triplestore is the most correct name

HN discussionI can only answer for one advantage I specifically know of regarding graph DB's over key value: dynamic, mergeable schemas which enforce data integrity WITHIN the database rather than with code on top of it. There are many, many people on HN who are much more knowledgeable than I am on graph DB's, and I sure as hell hope they answer on this question. I'm curious if this supports the RDF, OWL, and SPARQL standards? I…

HN discussionDatalog is awesome as is Logic Programming generally. It's not only useful in static program analysis but also in areas as diverse as synthetic biology and data integration. There's lots of datalog and similar technology in most Knowledge Graph platforms, too. For example, http://stardog.com/ .

on “The Essence of Datalog (2018)”Unfortunately a lot of stuff going on in the RDF domain is behind firewalls so it's a bit hard to give a lot of details. But I can contribute some public and some private use-cases of where RDF is used: Refinitiv (formerly Thomson Reuters Financial and Risk) knowledge graph is built completely on the RDF stack: https://www.refinitiv.com/en/products/knowledge-graph-feed When I talked to them in late 2017, they told m…

on “We are self-hosting our GPUs”Well, I'm a vendor in the space so I like my implementation: http://stardog.com/ -- and yes we've "tried it" with 10s of billions of edges. Worst cases are prevented from DOSing by having query management features like auto-killing queries that run too long, etc.

on “SWI-Prolog for the semantic web”RDF* or Edge Properties fixes this definitively and it's spread to most RDF systems. See http://stardog.com/docs/ for example.
