i know everyone is focused on the US elections but here's a small #SPARQL tip for those interested:
if you need to find all properties that instances of a certain class have (often useful for understanding a new dataset or visualisation), you can write a simple query like:

IMDB was recently looking for someone with “Expertise in industry-standard ontology languages and tools (e.g., OWL, RDF, SPARQL, Protégé)” Wouldn’t it be cool to have SPARQL access to all that… indeed.com/viewjob?jk=fbcd1e…

Sometimes, tools designed in one discipline can be unexpectedly utilized by researchers in another! Read all about the #SPARQL wrapper grlc and its origin story in this interview, and the surprising contexts in which it is now used.

I really like this but it’s got a learning curve ! Never convinced more than a few fellow devs on teams to embrace SPARQL : whenever Lucene syntax was an option, they used that (most prod graphs also support search in my experience)

[Help] "Learning SPARQL", the page 210 ex505.ru, I follow from ex503.ru, the copy result is correct, but why the move result miss the "two" triple? @LearningSPARQL

At the moment, currently working on a codebase I have no idea about(I learned about SPARQL queries this week...still learning 😭)
Makes me think about the way I view intelligence..the ability to quickly decode something and forge forward no matter how difficult or long it takes?

I know you've taken a hard stance on RDF, but if you're thinking about SQL for graphs, why not support RDF so you can use SPARQL? 😅

I don't get it. Is it an unsolved computer science problem© to have an RDF dataset supporting SPARQL and other graph operations backed by a relational DB? (Except for proprietary Virtuoso and such)
