“amr” Values specification addressing shepherd comments

OAuth logoDraft -03 of the Authentication Method Reference Values specification addresses the shepherd comments. It changes the references providing information about specific “amr” values to be informative, rather than normative. A reference to ISO/IEC 29115 was also added. No normative changes were made. The specification is available at: An HTML-formatted version is also available at:

Self-sovereign Identity System (SIS)

In a recent series of blog posts by Phil Windley, the concept of a self-soveriegn identity system is introduced.

SIS purpose is just like it sounds. An independent identity system managed by users. The series leads up to the announcement last week of Sovrin.org. (But I will get to that later.) Since these are in a series of blog posts, they are in reverse chronological order. So here they are in order.
  1. Service Integration Via a Distributed Ledger
  2. Governance for Distributed Ledgers
  3. An Internet for Identity
  4. Self-Sovereign Identity and the Legitamacy of Permissioned Ledgers
Some of these are lengthy. The topic is complicated, but fundamental to the future. Take your time. Dont let TL;DR syndrome sidetrack you.

In World of Ends, Doc Searls and
Dave Weinberger enumerate the Internet’s three virtues:

Twitter Markup

Twitter Cards are around for some time now and I recently wondered how commonly used they are?

There is a nice blog post on Blogger on how to integrate them there but clearly there should be ways for e.g. newspapers to promote their reports by providing summaries and a main image and author information that is not @Twitter specific?  Microformats and schema.org to the rescue?

What does Google do? It seems that JSON-LD is the recommended format.

How would a Twitter Card look in JSON-LD?

Twitter Cards or Rich Cards or @w3c Cards?

Time to standardize!

Announcing the Sovrin Foundation

sovrin logo on black background In London today, we're announcing the formation of the Sovrin Foundation. Sovrin Foundation is a private-sector, international non-profit that was established to govern the Sovrin Identity Network (SIDN). SIDN is a public, permissioned distributed ledger purpose built for identities. The Internet was created without any way for people and organizations to be identified. On the Internet, only machines get identities in the form of IP numbers. This is understandable given what the creators of the Internet were trying to achieve. But the lack of a decentralized, heterarchical, and interoperable identity system has created an environment where the services most people use online are a lot more centralized than the Internet they're built upon. Sovrin Foundation aims to rectify that. Using the virtues of Internet as a model, The Sovrin identity protocol uses a distributed ledger to replace today's centralized identity intermediaries. I believe an Internet-like identity system will create Continue reading "Announcing the Sovrin Foundation"

@Staples, you can Un faster than that.

I just unsubscribed from Staples mailings, and got this: screen-shot-2016-09-28-at-3-08-35-pm WTF? Is the request traveling by boat somewhere? Does it need to be aged before it works? We have computers now. We’re on the Internet. There is no reason why unsubscribing from anything should take longer than now. Staples is not alone at this, by the way.. Many unsubscriptions are followed by promises to complete over some number of days. I don’t know why companies do that, but it smacks of marketing BS. If you’re listening, Staples, give me a good reason. I am curious. For what it’s worth, I unsubscribed because approximately all the mailings I get from Staples (and everybody else) are uninteresting to me. Un-cluttering my mailbox is far more valuable than getting bargains (e.g. “$220 off select laptops and desktops” and “UNBEATABLE Ink & Toner Prices”) I’ll never bother with. Save
