Dale et al,
In doing some work on the BDX Use Cases and related matters, I came across the following that seemed potentially relevant to the DDDS work you’ve been leading, Dale – and perhaps our discussions of MetaData-related specs. I didn’t really feel competent to assess how relevant this is, if at all, but wanted to draw it to your attention.
In particular, “complications” noted in your document and elsewhere include:
·
Varied identifier schema, including emails, urls and ISO 6523 standard identifiers
·
The use of “special” (i.e. community-specific) domains for discovery / locator endpoints
In reviewing the OpenID Connect Discover spec, http://openid.net/specs/openid-connect-discovery-1_0.html#ProviderDisc I noted this section on Identifier Normalization, referring to the use of Identifiers including email, urls… but also referring to XRIs ( OASIS Extensible Resource Identifier spec here )
There’s also an XRI Wiki , that also refers to XRDs ( Extensible Resource Descriptors ) – and in particular on that Wiki, a DDDS Application for XRD Discovery .
See what you think.
Roger
