Intro

Contacts/social graph management is a (the?) core problem going forward and may (should?) be a core component of the DiSo problem space. -- Steve

XMPP

Contact import/sync via XMPP?

• PHP Jabber client - event-based, looks good.

Whitelisting

• In order to determine how to properly manage a whitelist, I think we need to do some mapping between the semantics of FOAF's "knows" property (per Dan Connoly FOAF and OpenID: two great tastes that taste great together), XFN's "contact | acquaintance | friend", and the status of a contact in an XMPP roster. -- Steve
• Dan Bricklin on FOAF/XMPP might be informative.
• The Microformats wiki has some interesting thoughts on this.

Issues:

• Trust: FOAF:friend vs XFN:contact vs XMPP:contact (roster item?)

Wouldn't trust be handled at an "application" level, in a more granular way? Explicit authorization? Or is this offtopic? --AlexandreSolleiro 18:11, 16 January 2008 (PST)

Discussion Summaries

"Certainly. XFN is the start and should be the basis for any relationship connections. That said, you might have "WoW friends" or "Favorite Photographers" and so on that don't fit those semantics, or at least are important enough that someone might want a way to call out those groups in their personal settings. Furthermore, we should again look at Facebook's or Gmails' approach to friend grouping for prior art:

"Well, what about being able to pull in a remote XFN list and match the remote identifiers with the local identifiers to see where your friends have commented on the blog you're currently reading? Seems to me that rather than think about this from a "friending" perspective, we should look at this from a functionality perspective... IF there are overlaps in friends lists between two people (or on two blogs), then what kind of information can we reveal that might be of greater interest to the visiting person? Think about the functionality that MyBlogLog offers and then distribute it off the central server... and think about what's possible. That's what should drive this plugin." -- Chris Messina

"When someone hits my site right now (http://boldlygoing.com), they'll see output from the three big networking sites: MBL, BC, and BumpZee. But all that output shows is whom from those networks have viewed my pages. Is there any reason that we can't create similar functionality with our work that could also show a visual representation of those that have left comments at my blog, and are DiSo-enabled? I would think that should be very easy given all that's swirling at this group right now." -- James D Kirk
