Hm, crazy idea...

So...I wonder if any one else would want to be able to tag other people's media with their own separate set of tags. Delicious does this by accident because every page can be bookmarked by anyone, and you can view everyone's bookmarks for a given link, but I don't know of other services that do this on purpose.

Some things that we tag are pretty cut and dry, so there probably won't be much variation of tags from one person to another. Links are a good example. A news story about a startup donut shop down the street fits rather specifically into one's perception.

But art is different. Art is supposed to hit people different ways. I imagine that stuff people put on their gmg instance will be art, and that visitors will experience a user's media in different ways. Let's allow for that

Make it so that each StorageInterface implementation has it's own submodule.

e.g.

- mediagoblin/
    - storage/
       - cloudfiles.py
       - mountstorage.py
       - basicfile.py

"medium" and "thumbnail" versions of JPEG files are stored with a lowercase ".jpg" name extension, but the original versions are stored with whatever case was in the original file name: jpg, JPG, jpG…

So you get something like this:

user_dev/media/public/media_entries/fa23ab31abf7ec67be8000001:
 originalFileName.JpG
 medium.jpg
 thumbnail.jpg

(If the file has a random extension like "dfsg", it is simply not accepted.)

The extension should be made lowercase, so that all sizes have the same extension both on disk and when downloading.
