What is the difference between Registry and Repository from SOA point of view?

http://www.ibm.com/developerworks/wikis/display/woolf/Registry+vs.+Repository

"A registry is a list of items with pointers for where to find the items, like the index on a database table or the card catalog for a library. A repository stores the actual items, like a database table itself or a library's shelves of books. If you lose a registry, the items still exist; you just may need to reindex them. If you lose a repository, the items are gone."
