Tentris is the first scalable graph database management system that provides accurate, real-time insights across distributed data sources.tentris.io Herford, GermanyJoined April 2024
Named Graphs: Elegant & kind of messy
They are like labeled folders for your triples.
Why they’re awesome:
Track who said what, where & when
Keep datasets modular so “Experimental” doesn’t mix with “Production”
Why they’re messy:
Too many graphs = “Wait, which triple is where?”
SKOS vs. OWL?
SKOS: "This is kinda like that."
OWL: "This is a formally defined subclass with logical constraints, thank you very much."
SKOS keeps it chill.
OWL brings the rules.
Use SKOS when you want labels.
Use OWL when you want logic.

Deep queries, lots of hops
Need to ask things like:
“Who’s connected to Bob, but not directly, and only through projects tagged with 🦄?”
That’s a graph query. SQL will cry.

Nanopublications: Tiny packages of trustworthy knowledge
Why read a whole paper when you just want one juicy fact?
Say hello to nanopublications which are tiny, super-smart knowledge bites packed with everything you need:
Assertion, Provenance, Publication Info
#KNOWLEDGE
B+ Trees have served DBs well, but for graph workloads, they hit performance limits.
✅Our hypertrie handles indexing far more efficiently.
✅It allows faster multi-join queries.
✅It reduces costly disk accesses.
👉Result: Lightning-fast query performance even at scale.
#GraphDB
WDBench results are in...
Tentris: “I’ll just handle 1.25B triples and be 5-10x faster while I’m at it.”
Everyone else: 🐢💤
We came to play.

The Tentris Beta has been live for 3 weeks now 🚀
Huge thanks to everyone who's tested, broken, questioned, and starred ⭐
Your feedback is 🔥 Keep it coming!
We're fixing, tweaking, and learning a lot.
Haven’t tried it yet?

WCOJ? Sounds scary.
But it’s just joins with superpowers.
Instead of joining two tables at a time (like SQL), Worst-Case Optimal Joins look at all relations together. Like a group chat instead of a phone call. Fewer steps. Smarter joins. Less pain.

SQL vs. Cypher vs. SPARQL
aka: How do you like to ask your data things?😄
🧱 Table: "Give me the rows that match this WHERE clause."
🕸️ Graph: "Find me nodes connected like this."
🧠 RDF & logic: "What triples exist that satisfy these patterns and maybe infer some magic?"
#data
Released Tentris v0.19.4
-Trigonometry & Exp functions from XPath3.1 are now supported
-Revamped Python bindings available on PyPI. Install them with pip install tentris
-Python logging is available now
-Variables tracking in BOUND works now correctly if variable isn't in scope
On-site hustling at Founders Foundation last week! 💥
Deep dive strategy session, fresh ideas, strong coffee and a lot of good vibes!

OWL: “This data is consistent... trust me, I reasoned it.”
SHACL: “Cool story. But does it pass the rules?”
Inference vs. validation.
Logic vs. constraints.
OWL and SHACL: like a philosopher and a QA engineer.
#SHACL#OWL#SemanticWeb
RDFS: "This is a Person."
OWL: "This is a Person, who can't also be a Cat, must have exactly one birthDate, and inherits stuff like a boss."
#OWL vs. #RDFS in a nutshell.
OWL = more expressive, more rules, more logic.
RDFS = nice and light.

Research news 🥳
The paper📄 "Efficient Updates for Worst-Case Optimal Join Triple Stores"
has been accepted to #ISWC2025 – International Semantic Web Conference! 🎉
Join us this November in Nara, Japan, where Alex will present it to the community.

Most devs reach for SQL or classic NoSQL. Fair. It’s the comfort zone.
But if you’ve never explored a graph database (especially an RDF triple store) you’re missing a superpower:
👉 Modeling complex relationships is suddenly… natural.
🎉 It’s official: Tentris Beta is LIVE!
✅ Download it
✅ Query more, wait less
✅ Help us make it even better
A high-performance, disk-based RDF graph database enabling graph analytics that were deemed computationally infeasible.
👉 Get Tentris Beta: tentris.io
Triple stores can handle versioning and distribution. Just don’t expect push-button magic. But if you expect GitHub + BigQuery out of the box... well, not gonna happen easily.
What’s the weirdest workaround you’ve seen so far?
