Hello: 

Excuse my insistence, but I have some scientific curiosity and you could help 
me with that. 

About 3 years ago I began to review the existing literature on the topic of 
ontologies and the possibility of managing the semantics of the data. I came to 
have exchanges via mail with the Protégé team, which uses OWLAPI and not JENA 
in its latest versions. 

I had the choice between JENA and OWLAPI for the development of my doctoral 
thesis. The results of my analysis were very clear, everything pointed out that 
I had to use OWLAPI, mainly for the support to OWL2 which was of paramount 
importance for me. 

However, I have noticed that the JENA community is a lot, but much more active 
than that of OWLAPI. Could you tell me a bit about those reasons that incline 
you to use JENA? 

I know that JENA supports the management of ontologies in external memory, 
OWLAPI does not have support for that. Anything else? 

Best Regards, Manuel Puebla.

Thanks Manuel for your email 
I know that OWLAPI has a complete support for OWL2; however, I have specific 
reasons to use Jena.

The OWLAPI framework provides support for OWL2. I have used it without any 
problem.

Thanks Lorenz 


What does it mean that "OWL2 support in Jena will be added in due course"? 

The documentation of Jena mentioned that Jena has a limited support for OWL2's 
qualified cardinality restrictions as the example you have presented, but are 
the other restrictions, existential and universal, supported? For example, 

hasChild someValueFrom Person 
hasChild allValueFrom Person 
??

OWL 2 supports more features, e.g. qualified cardinality restrictions like 

hasChild min 1 Person 

in OWL 1 you could only say 

hasChild min 1
