Hi aperture, chris, max

max: there is need for rdfreactor below...

It was Christiaan Fluit who said at the right time 26.03.2007 12:34 the following words:

Ok, I see that doing both is a good way.
For versioning ontologies, we could use OMV:

This would probably have all we need, or?
    

Looks all fine to me!

I do have one question. It's more or less related to other stuff that we 
already talked about.

It seems that we're going for an approach where each data source has its 
own vocabulary class/interface defining all its configuration constants: 
relatively easy to manage and makes things more clear and explicit for 
Aperture users.

How then do we achieve easy configuration of a data source instance? At 
the moment we have a central ConfigurationUtil class, what will become 
of this? A separate ConfigurationUtil per data source? Perhaps just 
regular setters and getters in the DataSource implementation class that 
manipulate the RDFContainer/Model of that DataSource? What do you propose?
  
for now, I would ignore the problem and shift it to the developers,
once RDFReactor/Tripresso by Max Völkel works again (stable), we can auto-generate classes complete with getter/setter methods automatically, from the ontologies. this is superior and much cooler than hand-coding.

I have no exact clue how to connect these generated classes elegnatly to our existing code, but we should at least hint it in the interface, to give the developer a hint where to find a RDFReactor object that will help. no idea yet.

best
Leo
