I am working on a small cultural heritage collection that features a few 
scrapbooks and photo albums from the early to mid-1900s.  This collection is 
the first at our institution to utilize METS for complex objects.  Given how 
new we are to METS, we're still feeling out how to make best use of it -- as 
well as cope with the limitations of our digital content management software.

For each scrapbook/album, I am creating METS records featuring two levels of 
descriptive metadata: (1) a parent DMD for the object as a whole; and (2)  
child DMDs for the many individual photos/drawings on the pages.  Our grant 
project is particularly fortunate to have a historian on board, which has 
allowed us to create rich descriptive records for most individual photos in 
albums and scrapbooks.  Perhaps the most important feature of these records is 
the identification of people in photos.  These names are obviously best 
captured in the child DMD for each photo, rather than the parent DMD.

I am curious how others working with similar materials are utilizing the many 
descriptive metadata records within a single METS file.  I would like to see 
these records exploited to their fullest capacity for search and discovery, 
but am unsure what would be the best scenario to make that happen.  Our system 
breaks METS objects into their many component objects.  What this means for 
resource discovery is that child objects as well as parent METS objects are 
searched and retrieved.  So a search that matches a child DMD will retrieve 
that component image file and child DMD, as well as the entire METS object and 
parent DMD.  For those of you dealing with complex, image-based materials like 
albums and scrapbooks, how are you allowing your many DMDs to be searched and 

Given our specific software in mind, it looks as if our collection may have at 
least three options:

1. Allow only parent DMDs to be searched/retrieved through resource discovery, 
but allow child DMDs to be viewed as the user pages through the METS object as 
a whole.

This kind of functionality might be possible if we can deactivate 
search/retrieval of child DMDs in our software.  According to this scenario, 
the child DMDs would *not* function as *access* points, but could provide 
additional information if a user finds a particular photo/drawing for which 
he/she would like more detail.  One particular problem this raises is the 
inability/difficulty of finding photos of specific people that are located in 
albums/scrapbooks through the search interface.  For example, if one searches 
Roosevelt and a scrapbook contains a picture of Roosevelt, but that name is 
only captured in a child DMD, resource discovery will not retrieve that image 
or scrapbook.

2. Allow both parent and child DMDs (and corresponding objects) to be searched 
and retrieved.

This is the current functionality supported by our software.  Using the 
previous example of searching Roosevelt, this would result in both the 
specific image of Roosevelt being retrieved (with this record indicating that 
this child object is part of a particular scrapbook), as well as the scrapbook 
as a whole.  Even if the relationship to the parent is specified in the child 
DMD, do you think this could be confusing for users?

3. Allow both parent and child DMDs to be searched, but retrieve only the 
parent METS object.

Actually, I'm not even sure if this is possible in our software, but we can 
always ask for enhancements, right?

Using the Roosevelt example again, this would result in the full scrapbook 
being retrieved for this query.  The parent DMD for the scrapbook, however, 
mentions nothing of Roosevelt, so this might result in confusion/frustration 
for the user.  They might interpret this as a false hit or otherwise get tired 
of paging through the scrapbook looking for a needle in a haystack, as it 

Unfortunately, our software does not include functionality that would allow 
the scrapbook to be retrieved but opened to the particular page on which 
Roosevelt is pictured.  This, to me, would be the best option, as access to 
the individual item would be preserved, but the item would also never be 
viewed outside its original context within the scrapbook.

Any comments/feedback on these options would be greatly appreciated.  Do any 
of these three sound better/worse than the others?  Can anyone think of 
alternative scenarios that would better utilize our metadata and facilitate 
access to important pieces of a whole?
