Could I further abuse of your kindness by asking a new question. Do you think that my strategy is the best one to convert into JAVA object ? We want to migrate a huge RDF to another storage system (Elastic Search).
Here is the current strategy: 1. List all uri root node based on a query 2. For each root node, get the sub-graph with reachableClosure and convert it to a model 3. Convert the model into JSON-LD Frame 4. Use a JSON-LD library to convert into Java object. 5. Use spring library to store java object into Elastic Search Thanks in advance -----Original Message----- From: Roland Bailly <roland.bai...@arhs-dev-be.com> Sent: lundi 19 juillet 2021 13:59 To: dev@jena.apache.org Subject: RE: Retrieve all sub resources from one resource in one model --- This is an incoming mail from an EXTERNAL DOMAIN.

Since I am using the Jena apache library, I prefer the JAVA solution but thanks for the describe. Thanks to all of you !
