Thanks, Jose:
You confirmed what Brian Freels-Stendel said.
Looks like I have my work cut out or me.

Subject: RE: Turning an item into a collection
George,
This is a bit tricky, but I think it can be done. Perhaps someone else can OK
this since I've never done it. If you have a test environment, try it there
and see how it works first.
(1) Make a collection a community.
I would create an new community and give it the name of the collection.
Now, that new community will have a handle but you want the handle to be the
one from the collection. So go into the handle table and update the handle
value so that the new community has the handle of the collection. You'll need
to know the community_id which will be the same as resource_id in the handle
table to do this.
Now go into Dspace and delete the collection you just put in the community.
Hopefully that will work just fine.
(2) Make an item into a collection
Create a new collection, and make it look like the item ( I guess you don't
care about the bitstream )
To give the collection the same handle as the item, go into the handle table
and give the new collection the handle value of the item. Again, resource_id =
collection_id.
Now go into Dspace and remove the item.
Then run
./dspace idex-init
You'll have created handles which will not exists in your system, but I think
that's just the price you have to pay to do this. I think this makes sense to
me, but if anyone sees some fault in this please let George and me know.

Subject: [Dspace-tech] Turning an item into a collection
Hi...
I have a collections which has items that contain multiple PDF bitstreams.
We are thinking of breaking these items up so that I have multiple items with a
single bitstream, to make searching easier for the user. I know how to do
that, but the other thing I have been asked to do, I am not so sure about.
I was asked to take the existing collection and turn it into a sub-community
with the same handle as the original collection. Also, to take the existing
items and turn them into collections with the same handles as the original
items.
So, if a I have a collection: "Cornell Reports" with handle 1813/7754 and an
item: "Cornell Reports Vol. 1, No. 1 - No. 4, 1967" with handle 1813/7755, I
would like to create a sub-community called "Cornell Reports" with the handle
1813/7754 and a collection called "Cornell Reports Vol. 1, No. 1 - No. 4, 1967"
with the handle 1813/7755.
Can I do that in postgres? I am not sure how to link an old handle to a new
collection or to move a collection into the community table and an item into
the collection table. Any suggestions?
