Structured data is most complicated—What do you do if someone has created a new file in directory D, but at the same time someone else has deleted the directory? I know of no optimistic algorithms for dealing effectively with this in the CSCW literature. CODA deals with directory structures (normal UNIX file system) but takes a very simple view of this, as it only flags inconsistencies and does not attempt to fix them.

Cache techniques are commonly applied in distributed systems to speed up data access. For instance, the Coda file system [35] supports disconnected operations and relies on a callback cache consistency protocol, keeping only the latest version of the file and propagating the modifications in parallel. In this sense, Cloud4NetOrg supports disconnected read and write operations. In case of conflict, Coda invalidates the caches, while Cloud4NetOrg, like other cloud-based storage tools, maintains all versions of the given file.
