DAO Layer for TDB store

[Adrián Quintana]

Hi All,
We have developed an ontology and we have stored it in a TDB store. We 
want to connect to it from a Java Web Service and, as it is recommended, 
we would like to connect through a DAO layer. We have been reading a lot 
about different solutions: jenabean, rdfbean, sommer, etc. and some 
tailor-made solutions: sirup, ONKI-API, etc. but right now we have a 
huge mess and it would be great if someone can spread some light on 
this. We would like a simple library or, even a java example, of a DAO 
layer planned for being connected to a TDB store.
Best Regards,
Adrián
