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.

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

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

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…
