JCR repository for photo gallery

[Angela Cymbalak]

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.

Hi Angie,

I'm not sure what the indentation here means?
CiAdrCity is duplicate, there is also a duplicate
security below (with different indent).

Still unclear about the indentation. The EXIF section
and file size (if that's not part of the section) are
per file. Does that mean a thumbnail is not considered
a distinct file? If it is considered a file, I don't
understand how it is possible to store different files
for one photo. How about marking the EXIF section with *?

hope that helps,
