As shown in the title, I read owl file which is generated by Protege to Jena, modified it by adding some NamedIndividuals, and I wanted to read the modified file by Protege. Things went on well until I open this owl file with Protege. Protege just can not read it! I tried every "RDF/XML", "RDF/XML - ABBREV", "N - TRIPLE", "TTL", and still nothing.
One good news is that when I use "RDF/XML - ABBREV" and delete all the NamedIndividual I added, Protege works. But I want my Individuals!!!
