RDF export based on a dialog to define schema similar to the one used fro Freebase alignment

[GoogleCodeExporter]

Hi, Richard Cyganiak and I (Fadi Maali) have an initial implementation of RDF 
export. It is packaged as butterfly extension but also we had to edit some of 
the existing files. I am attaching a patch. would be very glad if interested 
people have a look at it.
In addition to the patch the set of attached JARs should also be added to 
webapp/WEB-INF/lib

I also attached a text file describing the purpose of changed files and jars.

the schema design is under Schema menu, the export under Project > Export 
Filtered Rows

The code is kind of stable and working, some enhancements are still missed. 
would be very glad to hear whether you find that useful or not.

thanks

Richard & Fadi, thank you! That looks exciting! I'll try to incorporate your 
patch in very soon.

Fadi, could you just zip your extension's directory and attach it here? It'd be 
easier for me. Thanks!

Hi David, 
thanks for your response.
I attach the extension. I also attach a patch file containing changes to the 
core files without the newly created ones which are under the extension (not 
sure if needed but the code won't compile without modifying the core classes. I 
am not sure if this is a good way for the extension but I could not figure out 
a better way, for example, to add an option to the menu or to add a reference 
to the Project class to the RDFSchema I had to edit menu-bar.js and 
Project.java).

Thanks

Thanks, Fadi. A few more details please: could you tell me the versions and 
licenses of the jars? URLs to them would be great. Thanks.

By the way, I might have to take the member variable "schema" out of Project in 
favor of something more generic. (As it currently is, the core of Gridworks 
depends on the extension rdf-exporter, which is not right.)
