FYI Jena-based Components for Building Semantic Web Applications
http://www.lotico.com/index.php/Jena-based_Components_for_Building_Semantic_Web_Applications Speaker: Claus Stadler Location: Online on zoom ( https://zoom.us/j/955345345 ) Date: 2 April 2020 Time: 6pm CEST / 12pm EDT The basics of RDF and SPARQL may seem simple enough at first, but once one starts to develop a prototype, one quickly stumbles upon the same recurrent problems, such as: How can performance be improved by means of query caching? How can we deal with blank nodes? How to deal with result set limits? Apache Jena ( http://jena.apache.org/ ) is a powerful Semantic Web toolkit, however for the aforementioned issues it does not provide out-of-the box solutions. Our original motivation for our independent "jena-sparql-api" project was to address these issues in one central place, instead of distributing solutions - possibly with various degrees of quality - among our applications (e.g. RDFUnit, DL-Learner, LIMES). By now, the library has grown. Most notably, it now features declarative Java-RDF mappings and RDF processing with reactive streams.
