[OWLAPI-developer] Building a Class in OWL-API like in Protege 4.1 Using collections

[Daniel A. <Dan...@un...>]

Hi everybody,

I'm searching for a Way to build a new class using the OWL-API,
The Class is described in Protégé 4.1 using curly braces to capsule the
Individuals.

A Class describtion and the the resulting desired OWL is attached below.

And  of course my try to Build a class like it in OWL-API.

I hope somebody is able to help.

Many Thanks in Advance

Daniel


=================================================
In Protégé 4.1:
=================================================
Testclass:
Equivalent classes:
has_character some pretreatment
has_solids_content some{60.4}
has_substance some ({Fibers})
has_substance some ({Glucose})
has_substance some ({Fatty_acids})

Where Fibers, Glucose and Fatty_acids are individuals


==============================================
The Resulting OWL  after saving the Ontology
==============================================
