Re: 2) in Jay's last comment:

The FileNet API supports a fairly simple way of handling dependencies between objects in a batch. You can force the ID of a new object so that you can generate a reference to an object before the object is persisted in the repository.
In pseudocode it's something like this:

Id folderId = createId();
Id documentId = createId();
A = createFolder(folderId);
B = createDocument(documentId);
C = fileDocument(A, B);
updatingBatch.add(A);
updatingBatch.add(B);
updatingBatch.add(C);

You can also add an object to a batch multiple times to handle bidirectional dependencies.
A = createDocument();
B = createDocument();
B.setProperty("relatedDocument", A);
updatingBatch.add(A);
updatingBatch.add(B);
A.setProperty("relatedDocument", B);
updatingBatch.add(A);

I'm sure not all repositories support forcing IDs. But it might be a reasonable solution as an optional capability if variables get too complicated.
