At the very least, it probably would not be a centralized service like the current mixi. So let me think about it a little.
First, mixi’s features:
I. Information publishing
(1) Profile Page: The items displayed change depending on whether someone is a MyMixi friend
(2) Diary: Specify the scope of disclosure (MyMixi friends, their friends, or the general public)
(3) Reviews: Use amazon web service to review products.
(4) Messages: Can be sent to anyone.
(5) Albums
(6) Invitations: Invite friends
II. Information receiving
(1) Search (friends, communities)
(2) Profile display
(3) MyMixi diaries: Aggregate the diaries of MyMixi friends
(4) MyMixi reviews: Aggregate their reviews in the same way
That seems to be about it.
How to implement it in a distributed system:
I(1): Since the display only needs to change based on authentication and its result,
a website with authentication will suffice. SAML should do the job.
I(2): A blog with SAML authentication. The same applies to RSS.
I(3): amazon web service with SAML authentication.
I(4): There is no standard method for this. Perhaps the i-name contact service.
I(5): The same as a website
I(6): A request for authorization using a SAML Assertion.
In other words, all that is needed is a registration and authorization process
for that page using a SAML Assertion.
II(1): Google, or some registry.
For i-name, something like an i-name version of whois would probably suffice.
II(2): Simply viewing a website
II(3)(4): Simple RSS aggregation.
Well, it can be decentralized quite easily after all. :hammer:
Only I(4) would require a separate standard protocol.
