Attachment revision?

[Sven Helmberger <sv...@gmx.de>]

Hello!

I'm writing some multi-app hosting thing and besides using couchdb as 
database it also stores all images and stylesheets and scripts etc for 
the applications as attachments. I have one couchdb database per app and
store all resources on a single document to keep the same relative 
hierarchical structure I have in my apps.

I can now fetch that document and use it to quickly find out the name, 
lenght and content-type of all my attachments. When the document 
revision changes I know that at least one of the attachments has 
changed, but I don't know which.

Wouldn't it be possible to store the revision in which the attachment 
was created with the attachment?

_attachments could then contain these revisions as additional property 
and couchdb could use that revision as ETag when serving the attachment 
content which would be better than using the documents revision like it 
is now.

Regards,
