[Rdfapi-php-interest] Listing properties of a class

[Christian B. <chr...@re...>]

Hi to all,
I really don't understand if there is a simple way to have a list of all the 
properties of a class or of an individual (in OntModel).
With "simple" I mean something like $class->listProperties() (I know that 
already exists a method with that name but it doesn't do what I'm looking 
for). 

Thanks!
Christian.

In short: As far as I know, there is no simple way to do that.

Finding out which properties are available for a given class requires  
OWL reasoning in many cases. RAP doesn't have enough support for OWL  
reasoning to do that properly.

You can cover the simpler cases "the hard way" by finding the  
owl:domain and rdfs:domain triples in your model (or InfModel if you  
can).

Sorry about that.

Richard

that's exactly what I've done even if I was hoping in something
better...anyway I'll manage.

Thanks again,
ciao!
