Not typo, my data property in ontology was the same I used in Jena code but
I just made a change in its spelling to check it works or not and luckily
it worked.

So it means we have to use DatatypeProperty, ObjecttypeProperty instead of
just Property etc?
I still confuse, if we used OntModel, we should use DatatypeProperty or
OntProperty?

Nothing is "saved as annotations". Without using explicit OWL types, the
OWL API - which is quite strict -
is not able to determine the type of a property, thus, it's treated as
annotation property. and according to the OWL 2 specs, entities have to
be typed explicitly.

Thanks Dave and Lorenz, what I actually did now is just changed the name of
data property from Item to item, and now it works i-e saved it as data
property.
Thanks again sir for both of your kind suggestions.

You would need to ask the protege folks why they put it there, protege
is nothing to do with Jena.

Hello Dave, I have Item as data type property in my Protege ontology.

I am sorry my problem still exists and some values are stored as data
property and some still as "Annotations" though I used the same procedure
for all.
OntResource res=model.createOntResource(ns+ value); //value come from java
variable
OntProperty price= model.getOntProperty(ns+"ItemPrice");

Yes, in that case it is supposed to be an RDF property, thus not typed
as expected to be in an OWL ontology.

I used OntModel as model to read the ontology but used Property instead of
OntProperty, is this an issue?

For Protege it MUST be an OWL data property, otherwise the OWL API
parser will treat it as OWL annotation property. This has to be
explicitly declared in the ontology, the easiest way in Jena would be to
use an OntModel

What do you mean "Annotations tab"? Is this actually a question about Protege
usage?

Yes Lorenz sir I have written it to disk but it writes the data in the
Annotations tab rather than in the data property.
Customer1.setPropertyValue(price, pricevalue);
Customer1.setPropertyValue(quantity, value);
I want to write as data property values.

Ehm, did you write the model to disk? Without seeing any code it's like
to try a shot in the dark.

Next time after login as Customer1, previous data has not overwritten and
the owl file shows me old data also..

And using an IDE would also help, usually this is able to show you the

I used this: customer.setPropertyValue(property, pricevariable);
property here is property name:Item price and pricevariable is int value
but it gives me error of :

Remove the old triple and add a new one with the new value.
