The ObjectID is always 44 characters.
Hi all,  we are trying to implement a cloud storage for the users of our site. The site is a music store and it sells content from extarnal providers. The requirement is that when a user downloads an item for the first time then the item is also stored in his/hers music library and disk space. Other users that download the same item should have a reference to their library and disk space to the that first download.  I was thinking of using the object interface and tag the object with the library guids, but I'm not sure what the maximum number of tags and tag length that is supported by Atmos. If 1000 users purchase the same item will atmos 1000 tags?  The other approach is to create a file structure with a directory per user library where we will store the objects. My question about this approach is whether we can store, instead of the object, a reference to that first download.  I also was wondering about scalability and performance issues of those 2 approaches.  I'm looking forward to hearing any ideas you have.
