Re: Planning for a new framework for Jena

[Martynas Jusevičius <ma...@graphity.org>]

Joan,

take a look at the recent Graphity release, which enables a full
read/write RDF round-trip with Jena- and JAX-RS-compatible components:

On your site I could see a group of Semantic web sites accessible from your portal, and this portal generates a basic user interface, automatically I suppose. I suppose it's very easy to add new sites or repositories, and your platform generates a basic view-controller for the site, or allows the user to define their own view-controller. Correct me if I'm wrong, please.

Of course it could be linked with other sites or repositories.

Because of this I suggested the project to the Jena community, because I don't want to start a long learning period if the framework is useless or not needed for the community or already exists something similar.

The idea of my project, it's that you just download the war file, you deploy it, and all the configuration and management is done using a very helpful and user-friendly interface. Addition of modules, database configuration and administration, and so on.
