NetBeans plugin

Hello,

My name is Adam Radzimowski and I study at Jagiellonian University, Krakow,
Poland. I signed up here, because I am planning to write an ontology editor
as a part of my MSc thesis. Still, what I have now is just a blurry idea of
how such tool should look like.
My plan is to create a plugin to the NetBeans IDE that would include
elements such as:
- RDF (XML and/or N3 and others), RDFS, OWL editor
- graphical ontology editor with code generation
- SPARQL console with syntax highlighting and managing data sources
- a bunch of wizards, etc.
I tried to find something like that on the Internet, but I haven't come
across anything.

Would you consider such a tool useful?
What other functionalities would you welcome?
I will be grateful for any information and hint.

Thank you for any response,
Regards,
Adam Radzimowski
