URI Schema

This section describes the URI schema used for the logged RDF data. Every instance is prefixed with ${instanceprefix}, making the URIs unique. The instance prefix must be set in the Nabu Configuration.

Note: The URI schema is for internal use in the server only. You should not rely on the URI schema when processing RDF received by Nabu but use the properties linked to the resources. E.g. do not parse the date from the URI but read the nabu:datetime property!

Time Stamps

Time stamps are YYYYMMDD-hhmmss.fff (f for milliseconds)

Example: 20050416-221603.042 = 04/16/2005, 22:16:03.042

Account

Schema:

Accounts/$DOMAIN/$NODE

Example: frank79@… ==> Accounts/jabber.fsinf.de/frank79

Room

P2PRoom

Schema:

${instanceprefix}/P2PRooms/$ACCOUNT1/$ACCOUNT2

Accounts are ordered alphabetically (ascending):

P2PRooms/jabber.fsinf.de/frank79/serv-3100.dfki.de/schwarz

is the P2P room of frank79@… and schwarz@…. frank79@… is listed first, as jabber.fsinf.de < serv-3100.dfki.de

P2PRooms/jabber.fsinf.de/admin/jabber.fsinf.de/frank79

is the room of frank79@… and admin@…. admin@… is listed first, as the domain is equal and admin < frank79.

MUCRoom

Schema:

${instanceprefix}/MUCRooms/$DOMAIN/$ROOMNAME

For example, the room "support@…" has the URI /MUCRooms/jabber.foo.org/support.

Message

Schema:

${instanceprefix}/Messages/$ROOM/$TIMESTAMP

Example: A message sent by frank79@… to schwarz@… (or vice versa) on July 16th 2005, 22:16:03.042 has the URI:

Messages/jabber.fsinf.de/frank79/serv-3100.dfki.de/schwarz/20050716-221603.042

It is assumed that Nabu processes not more than one message per milli-second.

PresenceChange

Schema:

${instanceprefix}/PresenceChanges/$ACCOUNT/$TIMESTAMP

Example: A presence change of frank79@… on July 16th 2005, 22:16:03.042: PresenceChanges/jabber.fsinf.de/frank79/20050716-221603.042
