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=fbc…
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. blog.esciencecenter.nl/from-corridor-…

@jamie_maguire1 @carlcod_es Yeah there's an explosion of work happening in this space. I'm more interested in RDF / SPARQL than SQL tbh. I want to mine the data lakes for semantic knowledge.
