Subject: Minutes: XDI TC Telecon Thursday 1-2PM PT 2008-09-18
Following are the minutes of the unofficial telecon of the XDI TC at: Date: Thursday, 18 September 2008 USA Time: 1:00PM - 2:00PM Pacific Time ATTENDING John Bradley Markus Sabadello Drummond Reed Tatsuki Sakushima AGENDA 1) STANDING RULE BALLOT Drummond noted that we need to have a second ballot on the following Standing Rule: "Standing Rule: Does the TC wish to adopt a standing rule to conduct regular business only by electronic ballot, without Meetings, with the exception of Meetings called for a special purpose with a minimum of 15 calendar days notice?" # DRUMMOND to set up a new ballot. 2) TECH TOPIC: XDI CONTEXT DISCOVERY Eran Hammer-Lahav has posted an excellent summary of what is needed to move to a general-purpose metadata discovery protocol: http://www.hueniverse.com/hueniverse/2008/09/discovery-and-h.html Given that one of our planned XDI 1.0 specs is XDI Context Discovery, we discussed the use of XDI documents as one of the general purpose discovery formats, similar to XRDS, POWDER, RDF, etc. Discussion then focused on the protocol necessary to support such discovery, independent of the metadata document format. We discussed two messages that Dan Connolly had just posted to the W3C TAG public mailing list: http://lists.w3.org/Archives/Public/www-tag/2008Sep/0083.html http://lists.w3.org/Archives/Public/www-tag/2008Sep/0084.html We agreed with Dan that the missing element of the current definitions on the XRI TC wiki page... http://wiki.oasis-open.org/xri/AbstractIdentifierArchitecture ...was a statement about the assumption they were relative to a given communications protocol. The conclusion was that, given one communications protocol, the same identifier cannot be both abstract and concrete at the same time. The same identifier can, however, be abstract in the context of one protocol and concrete in the context of another. We concluded that this is an issue that needs to be resolved by those working on such a protocol (the XRI TC and others working on XRDS, the POWDER community, the RDF community, etc.). Once the protocol is determined, it should work as well for discovery of XDI documents as for any other metadata format.
