[OWLAPI-developer] I need help with the API classes that support SWRL rules

[Lamia A. Z. <laa...@vu...>]

Dear all, 

 

I need to be able to extract the  elements of a SWRLRule . so I need to
extract the body and the head and also retrieve all the predicates in the
body. An example rule is 

Excludes(?x,?y), Requires(?x,?y)] => problem(?x,?y)

I need to be able to extract the predicates  Excludes and Requires from the
body as an OWLObjectProperty. Also from the head extract problem as an
OWLObjectProperty 

 

I tried the following code but it doesn't work 

Set <OWLObjectProperty> p=
activerule.getBody().iterator().next().getObjectPropertiesInSignature();

 

Can someone direct me to how I can do this using the OWLAPI ?

 

Many thanks 

 

Lamia
