Providing metadata subscription services includes receiving a notification subscription request containing an item selected from a plurality of items residing in a repository. The items are stored in hierarchically-arranged levels of storage within the repository. Providing the services also includes determining that metadata of the item has been modified and creating a notification including changes made with respect to the metadata and any others of the items residing in the repository at a storage level equal to a storage level of the item and any storage levels that are lower than the storage level of the item. Providing the services further includes transmitting the notification to a user-specified first address and transmitting a copy of the item including the changes to a user-specified second address. The user-specified second address is different than the user-specified first address.
