Hi Sergio, here is an update: I did some tests using https://json-ld.org/playground/ to create different formats of JSON-LD(expanded, compacted, flattened) and RDFlib for SPARQL query (https://rdflib.readthedocs.io/en/stable/intro_to_sparql.html). The result is my tests: the namespace is not recognized well in expanded JSON-LD (see my first post); no results returned in compacted and flattened JSON-LD files with defined context. It seems to be a bug in RDFLib or do you have any working examples or further tipps for me?
