We just released Ontop 5.1.0! It brings support for nested data with most dialects through flatten lenses (beta), new SPARQL functions including casts, date-trunc and datetime extraction functions, new optimizations for left joins and more! ontop-vkg.org/guide/releases…

#timeseries can be handled very efficiently in a virtual #knowledgegraph . The new time functions in Ontop 5.1 make handling time data even easier. Ontop See comments for release notes.

Are you a Computer Scientist or Software Engineer looking for a rewarding career working with us on cutting-edge tech projects? We have a new opening for you: ontopic.ai/en/jobs/2023-0… Make sure to apply today! #knowledgegraph #knowledgemanagement

How can you leverage data in Databricks in enterprise knowledge graphs? A hybrid #knowledgegraph , composed of a graph database, a virtual graph and powerful graphical data mapping environment makes this possible. Want to know more? Register now at kgforum.ontotext.com/?ref=otevents.

What's in this new release: - metadata ingestion into the #knowledgegraph - multilingual UI - explicit commit message for project snapshots and much attention to the details, leading to a great the knowledge graph building experience. #knowledgemanagement #semantics

📣 Big announcement - a year after announcing our partnership w/ ontopic we are happy to offer a product bundle that will improve the process of building #knowledgegraphs & accelerate the time to market while getting better analytics & saving money. 🎉 ontotext.com/company/news/o…

We are teaming up w/ ontopic to provide the best-of-breed hybrid #knowledgegraph solution - an approach when #ETL is not suitable. Join our webinar on Dec 7 to learn how to quickly build a semantic layer on top of a #datalake: hubs.la/Q02b0n3B0 #datavirtualization

Had some pre-weekend fun mapping parts of the Swiss STATPOP population density dataset to OLAP/Cube RDF! Instead of materializing it as RDF triples, I use DuckDB as backend and Ontop as virtual graph layer so I can use SPARQL! linkedin.com/pulse/rdf-olap… #olap #cubes #rdf #sparql

🌟 Great News! Mark your calendars for the 3rd edition of our Knowledge Graph Forum! 📆 Join us on Thursday, May 30th, 2024, in Basel, Switzerland at Roche. Stay tuned for more details, and be sure to save the date! Curious about what the event is about? github.com/zazuko/knowled…

We're thrilled to announce that the Zazuko GmbH Knowledge Graph Forum is back for its 2024 edition and we are now accepting submissions for presentations! Join us on May 30th at the iconic Roche Tower in Basel: github.com/zazuko/knowled… #knowledgegraph #RDF

Just published: How we queried a billion observations with SPARQL using Ontop & DuckDB. A game-changer for RDF and large-scale data! 🚀 #sparql #rdf #Ontop #DuckDB #BigData #SemanticWeb linkedin.com/pulse/scaling-…

Nice use case for Ontop with AWS Athena and a S3 data lake

Sometimes, the small details make the difference. Based on our users' feedback, we did add more guidance to avoid the most typical sources of inefficient queries. Stay tuned for more features in the upcoming release of Ontopic Studio. #knowledgegraphs #usability #rdf

The ECOLOPES project reimagines city architecture w/ an integrated ecosystem focus on all organisms. It showcases using ontology-based #dataaccess, #RDF #graphdatabase, & #datavirtualization via Ontop & Ontotext Refine. hubs.la/Q02zQjVF0 #computationaldesign

Ontop 5.2.0 is out! Among all, it features fine-grained access control through special SQL functions and new optimizations for dealing with denormalized data. A big thanks to all the contributors, especially new ones! ontop-vkg.org/guide/releases… #RDF #virtualization #knowledgegraph

We just released Ontop 5.3.0. The main novelty is the upgrade to RDF4J 5.x (5.1.0), for which a new minor release of OWLAPI was needed. Thanks a lot to our contributors for this upgrade! And as usual, it also brings a couple of optimizations. ontop-vkg.org/guide/releases…

🗓️We took part in the kick-off of the project #CRIMA which aims to provide decision support tools using ontologies to combine scientific literature with quantitative data in the context of climate change adaptation👉bit.ly/43dzdYa #euinmyregion #eufunds #coesioneincorso
