Hi again, Andy,


the file content is given below (in p. s.). There is the ontology in RDF.
But as I said the code compiles, file is not updated, so, basically, when
the next time the file is read, no last entries/updates are saved.


You did remember to close the output stream, yes?

Produce us a minimal COMPLETE example.

+1

You've talked about changes to what you are doing so there isn't adefinitive example anymore.


Does the modified time on the file change?

Thanks,

My example did not read any file from disk - can you run that example and
get some output?

Thanks, Andy! I used the old library as an import, I can compile
everything, however, as I mentioned in the file is nothing added even I
am
using (the file is not upgraded with a new individual):

RDFDataMgr.write(out, model, Lang.RDFXML);

or

RDFDataMgr.write(out, model, Lang.TTL);

In this case I got an issue: "Problems reading ontology. Exception
message:
[line: 2, col: 1 ] Broken IRI (newline): rdf:RDF. Yes, my file is
RDF/XML",
then I do not get any issue, but the file is not modified with the new
insertion.


What is in the file?

  Dear Andy,

thanks for your piece of code and explanations, I can compile the code
if
I
use "model.write(out, "RDF/XML");" not "RDFDataMgr.write(System.out,

which
stores the ontology).


Maybe you are using an old version of the code.

  Regarding "RDFDataMgr.write(System.out, model, Lang.TTL);", I got the

error
that TTL can not be find.


... with no deprecations?  There is an old legacy class lang as well.
(and Lang should be package "org.apache.jena.riot", not
"org.openjena.riot")

Check the version of the code - the current release is 2.10.1 and you
need
all the jars on the classpath.

   Dear All,


thanks, Andy, for a piece of advice! So, I followed your advices, and
rewrite the code in that way. However, at the end met some problems.
In
the
case I use "UpdateExecutionFactory", I need GraphStore as a variable
which
I do not have because I have only ontology, not a graph.

  Ontologies are graphs.

          Anyway, it compiles after some changes, but I can not see any

  changes

in the file. My code looks the following way:
  This works for me: I don't have your data.  The output shows that it


contains the triple added.

If this does not work for you as you expect, please provide a
complete,
minimal example, a description of what does happen for you and the
reason
why it is not as you expect.
