Yep.

Yes. In particular, I have two different sets of use cases in mind. One  
revolves around understanding that something is like something else, but  
really not the same.

West Side Story, the Musical, is a version of Romeo and Juliet. Is this  
what you mean by "isBasedOn"?

West Side Story, the movie, is a version of the Musical, but there is a  
change to make the format. Is this a format of West Side Story, and is  
using a Wikipedia entry URL as the source a sensible thing to do?

Blade Runner is an adaptation of Do Androids Dream of Electric Sheep, and  
often called the book of the movie. But it is not really as close to the  
original as West Side Story is to Romeo and Juliet. Film adaptations are  
often pretty different from their original sources. Shirley Valentine is  
another example of a movie and play that are not all that close to each  
other, despite being very recongisably the same work.

Romeo and Juliet, the Baz Luhrmann movie, is a version of Romeo and Juliet  
in a different format. Is this a workExample?

There are also various text versions of Romeo and Juliet. I'm guessing  
they are all candidates for workExample/exampleOfWork.

The other set of use cases are where there is no clear "original".

For example, I write a new, interactive internet site telling a story  
about swans and ostriches. It is natively video, or text, or text and  
audio, and so on - you decide what pieces you actually view.

I could describe the resource as having multiple versions, each with  
different characteristics (format, language, ...) but the URL is the same.  
I think I want to use named graphs to distinguish these cases. (I want to  
do the same thing to handle the fact that there are effectively multiple  
versions of the resource with different accessibility characteristics, but  
the URL where you get the resource is the same).

I think it would be useful to flesh out my use cases a bit more, so they  
can be worked up into concrete examples with answers. But so far I don't  
see:

- How do I handle the distinction between "X is an original. Y is based  
somehow on X" and "X has multiple representations because it is true  
multimedia"?
- What is the difference between a play or film that is an adaptation of a  
book, and something that is just a retelling of the same story? How does  
that compare with a resource that is an attempt to adapt as literally as  
possible in a different format? (And how does that compare with  
translation - is the best translation of the Odyssey alliterative verse or  
blank verse or hexameter or prose)?

cheers
