RE: [bdxr] Identifier issues - "DDDS complications"

Hi Roger,

The XRI Wiki’s wiki specification of a DDDS application at least shows that DDDS has previously been considered as a template for metadata discovery services.

The OASIS XRI and XRD projects seemed to have encountered a lot of headwind.

Our approach, so far, sticks to reuse of IETF specifications and approaches, and does not try to “enrich” metadata associated with URIs/IRIs or URNs beyond what has been approved in joint IETF/W3C efforts.

Beyond generalizing to the pattern of a DDDS for service(s) discovery, it is unclear whether XRI/XRD approaches need be leveraged.

The history was full of “sturm und drang.” See  http://lists.w3.org/Archives/Public/www-tag/2008May/0078   And from the other side

Thanks Roger. I will take a look at it sometime this week and respond in (a bit) more detail.

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
