Listing a profile already listed -> Update

[acorbi]

When receiving a request for listing, first check if the particular profile has been already listed, for that it is necessary to explore the stored files and search for the URI where the profile is stored. If a file containing that particular profile is found, it should be ovewritten. If not, new created.

I understand you just want to fetch updated version of the profile and save it in listing?

@elf-pavlik Exactly, but without creating a new listing file on the directory in case that profile (about.id) was already listed. Correct me if i am wrong but i believe the actual implementation produces duplicated entries on the directory when an profile is listed for the second time.

@elf-pavlik the directory does not expose the PUT method through its API. Shouldn't we implement it also? Currently there is no use case for it but it would be usefull in case we need to somehow modify the Listing file.
