Or inversely the data we publish contains links to binary resources such as pictures, videos, or other less data oriented documents (works of literature, legal documents, etc...) For the data publishing to be complete, the binary resources need to be published with the data. Even when the binary resources are the primary concern of publication, the metadata that puts it in context is just as essential: when publishing a picture of space we need to know which telescope took the picture, which part of the sky it was pointing at, what filters were used, which identified stars are visible, etc... For more personal resources we want to know who appears in the picture, where it was taken, and who can see it. One may for example want to allow the access control rules to be edited by the people who appear in the picture.

Well publishing web documents does in my view require publishing binaries. 
I like web pages with images in them. :-)

I don't think that publishing a binary is going to be a big change. 
It's just a POST to a collection that allows image/* . It may be that
other specs can provide for that if it is too complicated. 

I think the user stories were more light weight ideas of things one could do
with the LDP.

I am probably not the best to provide context. The good news is that
it was decided today to start with the IBM submission and publish that
as a first working draft. I think it is then up to us who implement this to 
come up with simple changes to the document for the use cases to be implementable.
Clearly if those changes require 5 extra pages, then that would not be a good idea....

But others can perhaps provide more/different contexts...
