Parody 2.0

At the untalent show last Tuesday night we had some fun and some fine performances, including heathervescent‘s version of Total Eclipse of the Heart and several rounds of “PowerPoint Karaoke”, which (living under a rock as I do) I had never heard of before. Heather also invented the handing-out-drink-tickets method of getting people to perform — brilliant! Thanks to everyone who came up onto the stage, and to the event organizers for supplying the deejays.

To learn about my main contribution to the festivities, click to enlarge this all-important “Venn of identity parodies” diagram. (Who do I think I am — Paul Madsen?)

The Venn of identity parody songs

Here are the lyrics to the related ditty I performed, with apologies to Maria Muldaur (and the fine folks at OASIS!).

Midnight at the Organization for the Advancement of Structured Information Standards
(original lyrics here)

Midnight at OASIS
Send your SAML to bed
Touching all of the bases
Graces schedules up ahead
Madsen‘s working the website
Formatting’s gone bust
Let’s just separate MAY, SHOULD,
SHALL NOT, RECOMMEND, and MUST

Come on, Kavi is our friend
It’ll upload the spec
Come on till the ballot ends
Till the ballot ends
You don’t have to answer
You can just abstain
Mary‘s tally keeper
Deeper, to get us through the week

Gerry Beuchelt has already blogged another tune he and I warbled.

One last goodie: Click on the slide below to see a “singing presentation” that Gerry, Paul Bryan, and I prepared, with apologies to Dick Hardt

The Venn of identity

My SAML parfait diagram experiment went pretty well. I heard from a number of people who found it helpful, and one fellow even asked for the source (OpenOffice.org, need you ask?) so he could try tweaking it to highlight one profile/protocol to which I’d given short shrift.

At around the same time, some people who came across the SAML (and Liberty)/OpenID/CardSpace Venn diagram that appears in the RSA talk I did with Liberty Alliance director Brett McDowell asked me to post it because they thought it was generally useful. I’m definitely not the artistic type, but I guess I can draw boxes and lines — and bubbles — well enough! The following version isn’t quite as pretty as the RSA one because that was done by a professional graphic artist for the occasion, but I’ve continued to fiddle with the wording a bit so I needed my own copy. (You really do need to click to enlarge this one, to read it properly.)

Identity Venn diagram

Giving credit where it’s due: The main author of this diagram is really Paul Madsen, who sketched an early version during the discussion of the identity triangle diagram that Johannes Ernst put together, so Johannes deserves a hat-tip for his original series. And the title of the post is stolen shamelessly from my former Sun colleague Gary Ellison, who used it for a presentation to the JA-SIG on federation, identity, and web services back in 2003.

In the spirit of some of Gary’s diagrams but at a higher level, I recently did another Venn diagram to flesh out my “convergence touchpoints” material in the RSA slides, providing a view that stretches across federated identity and web services. I can’t credit/blame anyone but myself for this one. Really, it’s slightly more than a Venn because the shapes of the bubbles hint at horizontal applicability. (Again, click to enlarge.)
