Semantic conventions for JWT tokens.

[hsblhsn]

What are you trying to achieve?

I want to log my jwt token data into my trace and spans. But there is not semantic naming conventions to that. I found enduser.id but that is for storing only the end user. While a jwt token consists of lot of things like expiration, issuer, audience e.t.c.

What did you expect to see?

I want to see a standardized naming convention for jwt tokens.

The spans that would contain this info, what operation in your application would they correspond to? For example, would you just put this data on the top-level SERVER-type spans? Or somewhere else?

I’m reminded a bit of the enduser namespace: https://github.com/open-telemetry/semantic-conventions/blob/5077fd5ccf64e3ad0821866cc80d77bb24098ba2/docs/general/attributes.md#general-identity-attributes

edit: The enduser namespace is replaced by user as of May 2024; see https://github.com/open-telemetry/semantic-conventions/blob/5077fd5ccf64e3ad0821866cc80d77bb24098ba2/docs/attributes-registry/user.md

Can you list what data you want to store and the scenarios for using it? I wonder if those are reusable beyond the JWT token scenario or specific to it

This is what I am using right now:

const (
	AttributeKID             = attribute.Key("jwt.headers.kid") // public key id.
	AttributeID              = attribute.Key("jwt.claims.jti") // token id.
	AttributeIssuer          = attribute.Key("jwt.claims.iss") // issuer.
	AttributeSubject         = attribute.Key("jwt.claims.sub") // subject (user_id).
	AttributeAudience        = attribute.Key("jwt.claims.aud") // audience (my domain).
	AttributeAuthorizedParty = attribute.Key("jwt.claims.azp") // Authorized party (client_id).
	AttributeExpiresAt       = attribute.Key("jwt.claims.exp") // Expiry.
	AttributeNotBefore       = attribute.Key("jwt.claims.nbf") // Not before.
	AttributeIssuedAt        = attribute.Key("jwt.claims.iat") // Issued At.
	AttributePurpose         = attribute.Key("jwt.claims.purpose") // Purspose of the token.
	AttributeScopes          = attribute.Key("jwt.claims.scopes") // Scopes and permissions.
)

Here I am using the standard claim names of the jwt spec. I believe we can go further and use readable attributes and reuse them whenever possible. The above code is my very personal implementation.
