Re: [Jonto-users] [JOnto-devel] First boot failure

[Sebastian R. K. <seb...@de...>]

Hmm,

The only issue I had with new Sesame was that in order to add a new  
repository I had to run some command line stuff. Than another thing  
was to find where are the repositories on Mac and on Linux (http://blog.corrib.org/?p=29 
).

New JOnto has been written to support Rdf2Go - so in theory you should  
be able to use any RDF Storage that provides a plugin for Rdf2Go. I  
might be wrong - but the only class you would need to modify is  
JOntoRepository in base. Than you can use e.g., Jena2.

However if you will not set up  
org.corrib.jonto.db.rdf.respository.spec than JOnto will use zero- 
config Memory repository.

I hope that helps.

S.
