JCR repository for photo gallery

Here is a beginning to the structure of the JCR.  Of course, there 
are a lot of unanswered questions but better to start somewhere right?

A question I wasn't able to answer while reading the JSR-170 spec, do 
we have to keep, as part of the repository, who the owner of each 
workspace is or is that part of the information the implementation is 
supposed to keep?

For the IPTC data, I went through the spec and took each of those 
elements.  I figure, set up the repository to hold all the 
information and then take it out if we don't need it.  Can we assume 
that we can get any of this information from the images directly?  I 
also think I might be missing a few of the properties but haven't 
been able to relocate the information on them.


I took out a lot of the EXIF data because it just didn't seem like 
information that we should replicate.  But, I could be convinced otherwise.

Elements marked with a * can have more than one.
