Christopher did a great job outlining the history of internet identity standards, and introduces 10 Principles of Self-Sovereign Identity, currently in revision.
However, considerable additional material has been created on the subject since then, including some helpful criticism on the principles.
Resultingly, I've begun collecting as much source grade material on Self Sovereign Identity, as possible, organizing it here.
This directory was born from [WebOfTrustInfo/self-sovereign-identity](https://github.com/WebOfTrustInfo/self-sovereign-identity), *the original* SSI repository.
It would seem that Christopher Allen's [The Path to Self-Sovereign Identity](https://github.com/WebOfTrustInfo/self-sovereign-identity/blob/master/ThePathToSelf-SovereignIdentity.md) is still the most comprehensive article on the subject of Self Sovereign Identity. It outlines some of the underlying history, and introduces [10 Principles of Self-Sovereign Identity](https://github.com/WebOfTrustInfo/self-sovereign-identity/blob/master/self-sovereign-identity-principles.md), born from the collective thoughts on identity leading to it.
Considerable additional material has been created on the subject since then, including some helpful criticism on the principles. Some of initial thoughts have been organized in [evolution-of-ssi](/literature/self-sovereign-identity/evolution-of-ssi/).
While none of this is authoritative, it's useful to keep in mind the philosophy an principles that have developed around creating next generation digital identification schemes.
