When your OpenID provider goes offline…

┬áMy main OpenID provider is currently LiveJournal, delegated from my own danbri.org domain. I suspect it’s much more likely that danbri.org would go offline or be hacked again (sorry DreamHost) than LJ; but either could happen! In such circumstances, what should a ‘relying party’ (aka consumer) site do? Apparently myopenid has been down today; these […]

JQbus: social graph query with XMPP/SPARQL

Righto, it’s about time I wrote this one up. One of my last deeds at W3C before leaving at the end of 2005, was to begin the specification of an XMPP binding of the SPARQL querying protocol. For the acronym averse, a quick recap. XMPP is the name the IETF give to the Jabber messaging […]

Public Skype RDF presence service

OK I don’t know how this works, or how it happens (other Asemantics people might know more), but for those who didn’t know: At http://mystatus.skype.com/danbrickley.xml there is a public RDF/XML document reflecting my status in Skype. There seems to be one for every active account name in the system. Example markup: <rdf:RDF> <Status rdf:about=”urn:skype:skype.com:skypeweb/1.1″> <statusCode […]

Google Social Graph API, privacy and the public record

I’m digesting some of the reactions to Google’s recently announced Social Graph API. ReadWriteWeb ask whether this is a creeping privacy violation, and danah boyd has a thoughtful post raising concerns about whether the privileged tech elite have any right to experiment in this way with the online lives of those who are lack status, […]

Waving not Drowning? groups as buddylist filters

I’ve lately started writing up and prototyping around a use-case for the “Group” construct in FOAF and for medium-sized, partially private data aggregators like SparqlPress. I think we can do something interesting to deal with the social pressure and information load people are experiencing on sites like Flickr and Twitter. Often people have rather large […]

Open IDiomatic? Dada engine hosting as OpenID client app

All of us are dumber than some of us. Various folk are concerned that OpenID has more provider apps than consumer apps, so here is my little website idea for an OpenID-facilitated collaborative thingy. I’ve loved the Dada Engine for years. The Dada Engine is the clever-clogs backend for grammar-driven nonsense generators such as the […]

Flickr (Yahoo) upcoming support for OpenID

According to Simon Willison, Flickr look set to support OpenID by allowing your photostream URL (eg. for me, http://www.flickr.com/photos/danbri/) to serve as an OpenID, ie. something you can type wherever you see “login using OpenID” and be bounced to Flickr/Yahoo to provide credentials instead of remembering yet another password. This is rather good news. For […]

OpenID plugin for WordPress

I’ve just installed Alan J Castonguay’s WordPress OpenID plugin on my blog, part of a cleanup that included nuking 11000+ comments in the moderation queue using the Spam Karma 2 plugin. Apologies if I zapped any real comments too. There are a few left, at least! The OpenID thing appears to “just work”. By which […]
