I mean, what's the difference between having max_items=0 and
persist_items=false?

Yeah, exactly, we hardly have a good description of the fields in the
XEP-60?

Loosely, I agree with Sergey, except I think he means:
<field var='pubsub#max_items'
type='text-single'
label='The maximum number of items to persist'/>
Rather than:
<field var='pubsub#persist_items'
type='boolean'
label='Whether to persist items to storage'/>

Hi,
After having a look at XEP-0163: Personal Eventing Protocol and
XEP-0060:
Publish-Subscribe I'd like to have a clarification regarding the
multi-items
per node support.
PEP is meant to be a "a simplified subset of pubsub" and was defined
to work
with nodes created on the user JID. Also this XEP is mostly used for
nodes
that only contains one <item> (like in XEP-0118: User Tune, XEP-0107:
User
Mood, XEP-0108: User Activity or XEP-0080: User Location).
However some later XEPs allows clients to publish several items per PEP
nodes like XEP-0277: Microblogging over XMPP or XEP-0330: Pubsub
Subscription (we are also planning to update the Bookmarks XEP to
work this
way, one bookmark per item, mostly to prevent race-condition issues).
My main concern here is that a XMPP client currently don't have a way to
know if the server supports several items per node for PEP (like for the
current Prosody server).
Having this lack of information could lead to issues with XEPs that
rely on
this multi-items support in client implementations (that it's
actually the
case with clients like Movim).
I don't see any feature listed here
http://www.xmpp.org/extensions/xep-0060.html#features that could help
clients to get this information (maybe
http://jabber.org/protocol/pubsub#item-ids ?).
If its not a misunderstanding on my side, I'd like to have your point of
view on this problem and start to discuss about a solution.

Timothée Jaussoin aka edhelas
