The Elgg team are out in San-Francisco this week meeting up with some of the guys out here and talking about Elgg and ODD.

I will blog a bit more about it when I can, its been a bit mad so this is the first chance I’ve actually had to sit down at the computer since getting here (and I’m only able to do that because the combination of jet lag and the steak the size of my head I had for dinner last night has given me a case of insomnia).

I just wanted to share with you a thought that me and Ben had while enjoying the Californian sunshine inbetween meetings, namely a way to link ODD documents with OpenID.

For descovery of ODD documents, I was planning to use the meta / link approach similar to the way RSS is picked up. Now, it occurs to me that if we modify the spec slightly to say that a UUID should point to a page that can either be an ODD representation of the thing that it’s referring to or knows where to get it – i.e. has the appropriate header tag pointing to the url – then it becomes a trivial matter to turn a UUID into an OpenID URL.

Potentially quite useful.

  1. Why not just use XRDS-Simple?

    We essentially took YADIS from OpenID and made it compatible with XRDS — but subsetted our format (hence “simple”) so that people don’t have to implement full XRDS parsers.

    XRDS-Simple is also the discovery format of OAuth Discovery.

  2. @chris Thanks for the heads up on that, I’ll certainly explore it further. It looks – as you say – pretty simple!

    Btw. It was good to meet you at the Elgg meet yesterday, thanks for coming down.
