1)An interesting annotation in Alibaba is the @SPARQL annotation. I
guess the only way doing that with PA4RDF is an abstract/concrete
class with ARQ query inside ? Is there a way to get the URI of he
instance inside it ? (alibaba has the $this used in @SPARQL
annotation)
I'm not sure what the SPAR
Thanks all !
Martynas : I take a look on your application/framework. It means the
VUE is described in RDF as templates, isn'it? I will have to design by
example Quizz etc in RDF ? I guess I need some more hours to decript
how work Graphity, and I will do that when I get bored about
sesame/jena JPA
I was asked to comment on this thread and so as the developer for PA4RDF I
will.
PA4RDF was originally an interface only mapping: Annotated Interface
directly mapping onto the RDF structure with the Subject of the triples
being the instance of the interface and various properties of the subject

Nicolas: It is important to understand why would you like RDF into
JavaBeans. I mean in that case, a regular java application with RDBMS would
also do the job or? So, if you consider for a second, you would have
Javabeans being the objects updated by the application, internally you want
to convert
Nicolas: fair enough. However you should know that by simply replacing
the relational DB with a triplestore while using the same
object-oriented programming approach you're not getting even half of
the advantages of semantic technologies. RDF opens possibilities for
new software design patterns.

Martynas : Thanks for the link. Maybe your solution is excellent, but
I don't want to lose me : classical MVC, is a security for me and the
project.
Olivier : The Elmo documentation is great. Do you think my application
could be done with sesame ? I mean, sesame has a triple store, a
reasoner, an
Martynas,
that is a bit off-topic but maybe you could organize a webinar so you
can show us some features of graphityhq.
Nicolas:
honestly, i know not very much about PA4RDF,
I use Elmo (rebranded as AliBaba) :

Nicolas,
I suggest you also take a look at Graphity Client:
https://github.com/Graphity/graphity-client
You don't really need an object layer representing your RDF classes
above Jena, it is a bottleneck. You can express both the webapp
structure and the instance data as RDF, and define a mapping
Thanks for answers !
- About http://callimachusproject.org/ : interesting but I have to
create application from scratch, because very specific
- About PA4RDF : It seems very interessant. Any other tutorial,
related post or tip ?
Olivier, what do you exactly mean by "a bean <-> graph mapper" ?
I g
There was a discussion some weeks ago about PA4RDF.
It might be a good starting point, in you think a bean <-> graph mapper
could be useful in your case.
Also http://callimachusproject.org/ could be another interesting
project to investigate in your case.

Hello,
I am creating a web semantic application, were persistant data is all
stored in triple store (TDB).
I mean, users(foaf), parameters etc.
This application is an e-learning application, with exercices
proposition based on reasonners.
I want to use a classic MVC design pattern (jsp / servlets
