Hi Elias,

Thanks, and good to see you back (even if bruised)!

So you are suggesting that all documents get a global base URI, and 
that we use that to create stable URIs for embedded files (like 
images).

Right?

How would you suggest we specify that? Would it be enough to say that 
the document requires a global uri that is stable and unique, and 
suggest your lsid as a good option to achieve that?

Am thinking in some cases, an organization or user might want to 
specify their own http URIs as the base URI.

And what do you think of the idea I floated earlier to use the manifest?

  <manifest:file-entry
      manifest:uri="http://flickr.com/photos/doe/1";
      manifest:full-path="Pictures/foo.jpg."/>

In that case, if a uri is present, then that is used as the subject. 
Otherwise, one adds the path to the base uri.

I have no opinion on which is better; just asking.
