We are solving this a different way in onesocialweb and this could
become an extension to PEP and/or PubSub. Here is the flow:
- User subscribe to a node (e.g. urn:xmpp:microblog:0) with a bare
JID
- Event messages are sent to the bare JID and have a new type (e.g.
pubsub)
- The server does not forward the messages to connected resources,
instead, it puts the message in the 'PEP Inbox' (a pep node to which
only the owner has access)
- Clients interested in that content, subscribe to the PEP Inbox
using
presence based subscription
Okay, so let me see if I follow.
Conceptually, then, this is the user's account itself subscribing to
a remote PubSub node, and then the user's clients are then
subscribing to the user's own PEP node which acts as an aggregator?
From an implementation standpoint, this means the server has to look
inside messages inbound to the bare jid. I'm not *wholly* against
this, because these are fairly rare, comparitively - in fact, I think
the vast majority of such messages I get are already identi.ca ones -
but in general I'm not keen on servers having to look "inside"
without a type indicator, and I don't think adding a type is
practical.
So instead, I'm thinking about whether a subscription type of
"republish to me" is actually the way - ie, when I publish an item,
my server republishes it to the PEP nodes of each subscriber in turn.
(And yes, this technically isn't PEP as such anymore, it's some form
of PubSub-onna-jid). The downside is that this means that the S2S
traffic is now an <iq/> pair, but that does give us some form of
reliability and error control.
What do you think ? Worth moving forward as an extension to PEP or
PubSub (e.g. PubSub inbox protocol). Is there other ideas/proposal
out
there on the concept of a PubSub inbox ?
No, I do generally like the concept. I'm just wondering how to make
it more palatable
The thing I like more is the notion that this could unify the likes
of status.net and onesocialweb - I think that in itself is pretty
interesting.
