INTRO

This document discribes the server sync protocol.

DRAFT PROTOCOL DESCRIPTION

Version:

• Protocol version
• Model version

Node data:

• Public key

Object data:

• Post
• Post list (for sync)

The node requests other node's changes list since some time (since epoch if
this is the start). The other node sends a list of post ids or posts in the
XML or JSON format.

Protocol version is the version of the sync api. Model version is the version
of data models. If at least one of them is different, the sync cannot be
performed.

The node signs the data with its key. The receiving node saves the key at the
first sync and checks it every time. If the key has changed, the info won't be
saved from the node (or the node id must be changed).

Each node holds a list of networks it wants to get info from.

Each post has an ID in the unique format: node-id/post-id
