Hi, I'm trying to find some time to read about RDF for some time now, without very good results. I enjoy reading the list though, but I don't always have time to fully grasp the meaning so I give up. I thought I should give a try and say a word for something that made me click: (forgive me if I really don't have a real touch with the subject) Graham and Pierre made me think that what we really need is a way of describing data that are not always static. But what really stroke me is the need of a non static description. What if we could give a URL instead of an object (description in my way of thinking)? Or maybe, we could give a URL for every part of a triple. That would be extremely useful in say, software developing. The power of referencing to a triple in code without actually knowing it. Or just describing data that just don't stay the same, or don't really know what the data and description will really be. Please tell me if I get this right. I just couldn't constrain myself. Hopefully, my poor English are understandable.

Interesting point. Actually, I too had problems with the Car example, but that makes sense... I have another idea since a few days, which may be an alternate solution : the use of "anonymous" resources (which mean for me: I know there is a resource here, but I don't know its URI). We can use anonymous resources as subject or object of a statement. Why not as the predicate ?? [my:Car] --[ ]--> [my:Engine] I have a car, I have an engine, I know there is a relation between them, but I have no word for that... what do you RDFers think of that ?
